Tag: Schillner maps

By Michael Riley

The focus of this article is how the built and operating canals were surveyed and mapped. We might call these maps “As Builts,” since they show what had been constructed. Having a decent map would aid the engineers and maintenance crews in their planning and repairs. And was necessary for the legal departments who had to defend against damage claims. This article will take a look at the history these maps, and why you should be using them as a canal researcher.

Although the process would be similar, the work of the surveying teams who measured the land to determine the route of the yet to be built canal, was very different. The life and hardships of these men is the stuff of legend, and there are many books and articles about them. In his autobiography, John Jervis wrote about his early life on canal survey crew, which offers a look at how someone could start as a axeman and work his way up to becoming an civil engineer.ⁱ William C Young wrote about his time on a survey crew in 1816-17 which offers a intimate look at how the crews functioned.ⁱⁱ

Over the nearly 100-years of the towpath canals in New York State, thousands of maps have been drawn that show the canals. But only a few maps show the entire length of the canals, from end to end, in a scale that allows the researcher to see structures, nearby buildings and streets, and even property owners. The maps that this article will focus on are;

1) The 1834 “Holmes Hutchinson” maps of the early canals.ⁱⁱⁱ

2) The 1869 – 1874 maps of the Enlarged canals.^iv

3) The 1896 “Schillner” maps of the Enlarged canals.^v

4) The 1910 “Blue Line” maps.^vi

At one time New York State had twelve working canals covering nearly1000 miles, and not every map set will cover every canal. But rest assured that somewhere in the New York State Archives, there will be a map of your canal and it is likely that many of these methods described here will apply.

Surveying the Built Canal, and the Red and Blue Lines

For the purpose of this article, let us keep things simple and say that the survey process locates fixed points on the earth, while a map is a visual representation of the survey. An example might an old deed that says something like, “Beginning at a blaze on a apple tree near the road.” Here the apple tree becomes the point where the survey begins and all others will go to start as they retrace the survey or property lines. If the deed is from the early 1800s, it might tell you to, “walk 14 paces to the rock in the stream and then follow the course of the stream down to the bridge.” This is the Metes and Bounds method of surveying. Over the years the process improved and became more scientific that used measuring instruments. Thus you will see phrases such as; “runs thence north 20 degrees 45 minutes east, two chains, 4 links.” Whatever the method, by repeatedly finding and connecting points in the landscape, a survey will be created. Later, by using the survey and notes, a map could be drawn.^vii

This method of a boundary survey works fine for determining the outline of a piece of land. But on a long and linear canal, that might have been built through wetlands or deep cuts, it would be impractical to try to measure the properties boundary. Instead, another method was used. As the canals had a nice flat towpath, it was a simple matter to layout a line along the towpath and use this as the base line from which all measurements were made. The base line, shown on the survey notes and maps with red ink, became known as the red line.

Wherever there was a change in the canal, such as a change in direction or the width of the canal, or to note a structure (bridge, aqueduct, or lock, etc), the surveyor would stop and establish a cross section. The cross section was perpendicular to the red line running to outer edges of the canal property. Using the red line as the base, measurements would be taken to the outer edge of the towpath and berm embankments. So keep in mind that any red line on the map is a line of measurement.

Once the surveys were completed, a draftsman would use the survey data to draw a map. With the red line and cross sections laid out on paper, the outside boundary of the canal land could be roughly determined by drawing a line that connected the end of each cross section. Since blue ink was used to show this line, the “blue line” became the term for the state boundaries. This is why the drainage ditches on the outer edge of the embankments were called the “Blue Line Ditches,” and the maps are called the “Blue Line Maps.” Just keep in mind that the blue line was not measured, it was inferred.

In 1891, a newspaper article said; “What the Blue-Line Is.” The “Blue Line” is often mentioned in the course of the pending great debate in the senate. A brief explanation of what the Blue line is may be of interest. This line was established by the canal board when the canal enlargement of 1840 was made. The engineer corps, in surveying for the enlargement, indicated on its maps with a blue line the boundaries of the lands which were deemed necessary for State purposes. The irregularity of the line is explained as having been caused by adaptations to the needs of the canal. Where there wee embankments or streams or other peculiarities, the line was made to conform to these conditions as they were thought to affect the canals. The rule was to run the line five or six feet outside the limit of land absolutely required. The indication by the blue line was a formal taking of property by the State and extinction of the title of formal ownership.^viii The date of 1840 in this article appears to be slightly in error as the first instance of the use of a blue line was with the 1834 canal maps. The term “blue line” would later be adopted for the line that shows the state lands in the Adirondack Park.

Field Books and Monuments

A part of the survey teams tool kit were small note books in which they recorded their measurements and notes. In order to not turn this article into a book, it will suffice to note that these note books were used to record not only what the surveyor was measuring, but also what was around them. All the data you will find on the finished maps will be found in the field books, plus more. If you are exploring local history, and what may have been around the canals, be sure to check the field note books. Don’t assume it will be on the maps.

Below are two versions of the 1830s Holmes Hutchinson field notes, showing the Erie Canal in Port Byron, NY. The rough draft was likely done in the field while the other was a cleaned up version, perhaps drawn in the office. The survey shows the canal crossing the Owasco Aqueduct and passing Beach’s Mill. At the time the mill was one of the largest in the state and used the canal for receiving grain and shipping flour. Note that the canal is represented as running straight up the page, while on the map, the canal has quite the bend.

As noted prior, all surveys need a physical point in the landscape where the measurements begin. These might be called a bench-mark, a hub, or a monument. While the older surveys used anything that was prominent in the landscape, such as that apple tree, eventually the tree would died and the stump dug up. And as more property was sold and divided, conflicts arose as to the lines of ownership.

In 1827, Governor DeWitt Clinton recommended that a survey of the state be made and a map drawn. Nothing happened with this. Then again in 1852 and ‘53, the governors stated that a state-wide survey be made, but nothing happened. In 1875, the American Geographical Society reported; “that the existing maps, made from these old land-parcelling surveys and by private parties, were as nearly worthless as possible.”^ix The state finally relented and began a survey in 1876.

To begin their survey, the State used monuments that had been placed along the Atlantic coast by the United States Coast and Geodetic Survey, and and monuments around the Great Lakes that had been installed by the United States Lake Survey. These would serve as the foundation for their survey. If the survey was carried out correctly, the two should meet at exactly the same place somewhere in the middle of the state. This survey went on up to 1884 when the Governor vetoed the funding. It was restarted in 1888 by the U.S. Geological Surveyor and continued ever since.

As part of this survey, monuments were placed in the landscape that noted true north. Any surveyor could then use one of these to begin their measurements and thus, everyone would be working off the same grid. Interestingly, the canal itself would often become the place of permanence in the landscape and many deeds will often mention the blue line of the canal as part of the survey, even though in many cases, the line of the canal was often in doubt.

The 1834 Holmes Hutchinson Maps

As noted, the 1834 Holmes Hutchinson (HH) maps are a set of “as builts,” meaning that they are a record what had been built. During the canal construction, property was often taken and the state had no record of what was what, and who was who. The HH maps were made to fill that void.

In the HH collection, there are a total of 18 volumes showing five canals. The Erie Canal is shown in 10 volumes, with about 540 maps total. All the Hutchinson map sets have a set of Explanatory Remarks that go into detail as to how the map was drawn, but here are the basics with some added comments.

For surveyors of that time, the method of measurement was the 66-foot-long chain, otherwise known as the Surveyors or Gunter Chain. The chain had 100 links, each .66 of a foot or 7.92 inches in length. A mile would be 80 chains long (66ft times 80 chains = 5280 feet or one mile). The were drawn at a scale of two chains to the inch, or one inch equals 132 feet (66 times 2 = 132 feet), and all measurements are shown as chains and links. The measurements seem to run from west to east, although I have yet to find a point of beginning. But knowing where the surveyor began doesn’t really matter with this type of survey, because at every cross section, the measurement is reset to zero. So it goes something like this; start here- measure 2.50 chains to a cross section- stop, note the distance and measure the cross section, then reset and restart- measure 4 chains- stop, make notes, etc. In total, the measured distance was 6.50 chains, but it is not represented in that manner. On the colored version of the maps, it is easy to see where each measurement ends as it is noted with as a solid red cross section line running across the canal.

Confused? There is more. There are also places where an intermediate measurements were taken, meaning that the distance, bearing and cross section were noted, but the measurement continues. These intermediate sections are shown as dashed red lines. So you will see: start- measure 1.5 chains, stop to note measurement, continue- measure 3.0 chains – stop and reset to zero.

All compass headings are shown using the quadrant system where all headings begin either North or South, and then work between 0 and 90 degrees East or West. The heading N 88 E shows us that the canal was pointed 88 degrees east of north, or almost due east.

The HH maps are wonderful to study as they include the built and natural environs around the canal. Stores, businesses, property owners, roads and streets, prior canals, creeks, rivers, mill races, steam and electric railroads, historical sites, and more, can be found on the maps. The maps only include those features that are within a block or two of the canal, so in places where the canal passed through a city or village, you see a slice of the neighborhood. As they were drawn in the 1830s, these maps are often the first ever made of many villages and cities.

The 1834 HH maps were accepted and certified by the Canal Board, the Board of Canal Commissioners, and the Comptroller’s Office, as the legal maps of the State of New York.

The 1869-1874 Enlarged Canal Maps

The 1869 maps are another set of “as-builts,” showing the recently completed Enlarged canals. The funds to survey and complete the maps was provided by Chapter 543, Laws of 1866. The law states that the funding was to defray the expense of completing the work. This seems to suggest that the maps had been in the works prior to 1866, but there may have been an issue within the engineering offices as the act also notes that a uniform style of map had been adopted. The maps were completed in 1874. The Archives has them listed as B0292 in various volumes.

The maps were drawn in the offices of the division engineers, beginning with Van Richmond’s in the east. The 1869 “Richmond” map shows the canal from Albany to Rexford. These maps use the 66-foot-long Gunter chain, and many of the methods of measurement that were used on the Hutchinson maps apply to these. And yet, there are notations that tie the surveys, in some places, to local monuments. You can see these in the Cohoes area. As these maps predate the statewide surveys, it would be interesting to know what the monuments were. And other base lines were used to tie the survey to the landscape. In this way, these surveys are a bit more “scientific.” However, the maps are lacking in many of the details seen on the other maps. While they show nearby streets, and even the outline of blocks, they show only a few canal side buildings. They also show the route of the early canals. The maps were never certified but they were used by the state.

The 1896 Schillner Maps

The Schillner maps came about as a result of the 1895 Improvement, also known as the nine-million-dollar deepening. The project was passed as an legislative act under Chapter 79 of the Laws of 1895, which called for the deepening of the canal by two feet, from seven to nine feet.^x To support this work, surveys were made of the Erie, Champlain and Oswego in the winter of 1896 while the canals were shut down and drained. Although the main purpose of the surveys was to provide data to the engineering department in their efforts to create estimates and let out contracts for work, they were later used to create the1896 maps.

In the complete Schillner map archive, there are 71 rolls of three canals; the Erie, Champlain and Oswego. There are 53 rolls in the Erie set, 10 of the Champlain, and 8 of the Oswego. Physically, these maps are large at 234 x 183 cm, or 94 x 73 inches, Each roll is divided into four, five or six “frames” stacked top to bottom, each one running horizontally across the full width of the roll. Each frame is 30 to 60 cm, or 12 to 24 inches, in height. The height of the frame is governed by the complexity of the canal at that point, such as if it is passing through a populated area, or maybe somewhat twisting. So basically each roll will show 4, 5 or 6 segments of the canal. Each segment shows about 6700 to 6800 feet, or about 1.28 miles. So if you were to cut up the map and line each section side to side, the map would show between 4.8 to 7.8 miles of canal. These maps have been digitized. This divides the map into smaller bite-sized chunks of 10 to 30 plus images. Additional images were made of the locks and other notable features with a tighter lens and this adds to the number of images per roll.

(map-layout)

We know the survey process used for these maps as it was outlined in the Annual Report. The Erie, Oswego and Champlain canals were divided into 28 sections that had an average length of 18 miles. (Note- these are not the eleven canal maintenance sections that are mentioned in the annual reports. These sections were only used for the 1895 canal improvement survey and later the 1896 maps.) Over 200 men were pulled from the civil service lists to act as assistant engineers, rod men, chain men, ax men, levelers and laborers. The work began in January 1896 and lasted throughout what they all said was a very harsh winter. The teams first laid out a base line (the red line) with stations every 100 feet using the Ramsden Engineers chain, or Paines steel measuring tape.^xi All measurements on the maps are shown in feet and inches.

Selected stations, or a point of measurement, were tied to the ground by the use of bench marks. These bench marks ranged from iron spikes driven in between the stonework of canal structures, telephone poles, corners of buildings, fence posts, iron rods or wooden pegs driven into the ground, and more. Although the red line continued to be the inside edge of the towpath, to make it easier to work and set up the equipment, the line was “off-set” to the middle of the towpath. The off-set is shown on the maps with green ink. Once the red, and green, lines and stations had been established, the teams went back to run cross sections every 100 feet, or so, depending on the nature of the canal and what had to be removed or modified.

A big departure from the earlier maps was that each of the 24 sections were measured as one unit. The survey began at the east boundary line and worked to the western end. These measurements are show along the green line as small circles with a corresponding green numbering as needed to mark the location of structures, to aid the count, or bench marks. It appears that bench marks are noted as small triangles. So keep in mind that if you want to use these maps to locate a structure, the station count will reset to 0.00 23 times. I note this because in1905, Nobel Whitford also used the 100-foot-stations for measurements in his “Tables of Existing Structures On Canals.”^xii However, he used a continuous measurement beginning at the Hudson River.^xiii The blue lines are inferred by connecting the ends of the cross sections.

(diagram-003)

As with the Hutchinson maps, these are very useful in showing the built and natural environs around the canal. The Archives listing says that, “In addition they show: city, town and county lines; streams, rivers, bodies of water and islands; property lines, along with names of owners and sometimes acreage of land; and streets, railroad lines, businesses and civic landmarks (ice companies, mills, cemeteries, etc.).” Basically anything within a couple blocks of the canal are seen.

The maps also are very useful in showing the route and some features from the Clinton’s Ditch canal. The older canal is represented with a combination of red and blue dashed lines, and/or black ink drawings that show a “shadow” of what once there. The use of shadow lines and ink wash seem to emphasize areas of note such as locks, basins, drydocks, etc. In addition, the maps include the 1834 cross section measurements with the old chain measurements converted to feet, and the older compass bearings. It does not include any of the linear measurements between the cross sections. Maybe this would have made the maps too busy, or perhaps Schillner felt it was unnecessary as anyone who needed them could simply pull out the old 1834 maps? The old canal does tend to wander off the Schillner maps in places where the two canal routes diverged, but it always comes back. It does appear that Clinton’s Ditch was added in the office and not surveyed.

Although the work on the canal improvement was ordered to stop on March 8, 1898, the work on the maps continued as the state needed up-to-date maps. The Middle Division engineer noted that in addition to the work on the estimates, the survey teams were also gathering information that would be used by the State Board of Claims in defense of lawsuits that would very likely be lodged against the state for damages. He somewhat hopefully added that the survey data cold be used to; “create new set of canal maps, as there has been many changes in the canals since the enlargement which are not recorded on the maps now in use.”^xiv Maybe he knew something was in the works. In 1921, Anson Getman, wrote that in 1896, George L. Schillner had, “commenced a compilation of all maps of all lands which had been acquired for canal purposes to that time,” and that the Canal Law of 1894 ordered “the preparation of complete manuscript maps and field notes of every canal then or thereafter.”^xv So it certainly appears that Schillner and the others were working under two or more of these laws that were addressing different issues. You will also find these maps as being completed under Chapter 569, Laws of 1899. which was an act making appropriations for certain expenses of government and supplying deficiencies in former appropriations. One of the many projects listed was; “For the state engineer and surveyor, for completing new blue line maps of the Erie, Oswego and Champlain canals,…”

Getman noted that the work on the maps took 12 years, ending in 1908. Schillner’s name appears on other projects during this time, so the maps were not his only job. Getman also noted that the maps had not been certified by the State Engineer or approved by the canal board, so they “bear no endorsement.”

Getman might be the first person to add George Schillner’s name to the maps. Perhaps the maps were George’s pet project and the guys in the office just started to call them the Schillner maps? No one says. In 1939, the 1896 maps were introduced as evidence in the case Northern New York Power vs New York State, as the “Schillner Maps.”^xvi This is odd as there is no mention of the 1910 maps. But being used as evidence in a trial seems to show that the court accepted the maps as somewhat “certified.”

By the time the 1896 maps were complete, the state was deep into the Barge Canal project. The maps, as nice as they were, showed a canal system that was disappearing.

The 1910 Blue Line Maps

Amazing, for all the work that went into the 1896 maps, they were never certified by the state. Instead the state passed Chapter 199 of the Laws of 1910, which was; “An act to provide for the mapping of certain canal lands and the lands adjacent thereto belonging to the state.” This act was certainly in response to the pending abandonment of the old canals as the new Barge Canal was brought into use. Within a couple years, the state would be in the position to begin selling off these lands and they needed a certified legal survey and map that would become part of the record. The 1910 Annual Report notes states that the only “official” canal map was the 1834 Holmes Hutchinson map, and that the purpose of the 1910 Act was to re-establish the boundaries of the canals that were being enlarged into the Barge Canal system.^xvii

The Archives listing says; “This series consists of whiteprint copies of original survey maps, commonly referred to as “blue line maps,” of land appropriated by the State for canal purposes. The maps depict in minute detail lands acquired for canal purposes up to and including the time of construction of the Barge Canal. The Department of Public Works (earlier the State Engineer and Surveyor) produced and retained the original maps and submitted whiteprint copies to the Comptroller and Secretary of State. This set of maps was filed with the Comptroller. Laws of 1910 (Chapter 199) and 1917 (Chapter 51) authorized the production of “blue line maps” (the blue lines indicated boundaries of State-owned lands along the Erie, Champlain, Oswego, Black River, and Cayuga and Seneca canals) to minimize property disputes resulting from the construction of the Barge Canal. The maps depict inner angles of the towpaths on the old canal; property owned by the State prior to Barge Canal construction; property appropriated by the State for the Barge Canal project; locations of the old canal lines; location of the proposed Barge Canal; and various structures, roads, streets, and other landmarks and the names of owners of private property adjacent to the canal.”^xviii A quick count of the maps showed 1029 maps in 71 volumes. The scale used was one inch equals 100 feet. The maps have a key, which is needed as the volumes do not run in sequential order.

Before the survey crews were assigned, the office of the state engineer made “survey” of what records they already had on file. In addition to the 1834 maps and field books, the 1869 maps were examined, and the “rolled maps” and ‘Nine Million’ surveys, which were called the “most valuable compilation existing,” but were also not considered to be of much value.^xix One of the issues was that the older surveys and maps used compass bearings that were magnetic and not off the true meridian. And as the canal was so long, other factors such as the curvature of the earth had to be accounted for. All new surveys had to be conducted to re-establish the red and blue lines.

As they conducted the surveys, the teams used three-quarter inch iron pins to mark points on the blue line boundaries, and brass monuments to mark the red line. The brass plate had “ears” that were embedded into a concrete column that was eight inches round by 54 inches long. These were buried in the towpath along the red line. The top of the monument said; N.Y.S. – CANAL RED LINE MONUMENT, with blank spaces where the survey team would use a hand punch to add the station measurement and offset. (Sadly most of these have ended up in collectors hands over the years. Any that remained were plowed up by the contractors during the construction of the Empire State Trail.)

By comparing the 1896 and 1910 maps, certain stations can be found on both, however the noted measurements do differ. Plus, the 1910 maps used two methods to establish base, red and blue lines, and the title page should be consulted if you are taking a deep dive into the measurements. The big difference between the Hutchinson and Schillner maps, and the 1910 maps, is that the blue line was surveyed and monuments placed so that; “Blue line points can be relocated by using the data shown on the map.”

The 1910 maps vary in what canal side features are shown. For instance, the little village of Pattersonville is noted, but few buildings are seen, while 3 miles away, the details for the village of Rotterdam Junction are a bit more robust. The maps also take an interesting approach to the new Barge Canal. The new Barge Canal Lock 10, dam 6 is shown fully constructed, however Lock 8, dam 4 is not even noted, and Lock 11, dam 7 merely shows up as dam piers.^xx This is a bit odd as the work on the maps went on into the 1920s, so they certainly had time to update the maps and show the full lock and dam structures.

The work went on for over 14 years. In the Annual Report of 1924, the State Engineer wrote that the work was almost complete. He said, “It is not a simple process, however, to prepare these lands for sale. Extensive surveys have to be made, maps must be prepared, and in these activities precautions taken which will insure accuracy of the surveys and correct descriptions of the lands. In preparing for the surveys it is necessary to examine old maps and deeds back to the first canals of the state, nearly one hundred years ago, when surveying and mapping was not the exact science it is today. In addition to the men required to examine the titles and plot the lands, survey parties are required to define the lands in the field, and others to prepare blue line maps for the Canal Board and to follow these with abandonment maps and descriptions. To survey one mile of old canal in a month is a good average rate of progress for a field surveying party.”^xxi However, he added that the costs of mapping were not as high as continued maintenance of the old canal lands.

For those who wish to know everything about the maps, you might be wondering what the crosses with the numbers might be. I asked someone who used to use these maps in his day to day job, and he thought it might be part of a quadrant system that was tied to a master map. But he honestly wasn’t sure.

In Conclusion

If you have made it this far, congratulations, for you are a real map geek!

I picked these four map sets as they offer the most comprehensive view of the canals, its structures and canal side neighborhoods. However, the New York State Archives listing of maps is very extensive. There are over 140 volumes of maps in B0292 alone, with a great many of these dated between 1850 and 1880. So even if one of these sets missed a canal you are interested in, there is likely a map of it in the collection. Also, remember that other repositories will often have these maps, so be sure to check with the Canal Society of New York State or the Erie Canal Museum.

Steven Talbot has a great mapping webpage at Enlarged Erie Canal Map Viewer and he also helped me out with this article, so please take a look at what we has done.

And if you are a surveyor, and I got something wrong, please contact me!

Here is a comparison showing Sprakers, NY, with three of the four maps.

The Hutchinson map of Sprakers. The canal crossed Flat Creek on a small slack-water pool . You can see where Ferry and Clinton Streets ran up to the basin. (crop of 97 Erie HH Map Root & Canajoharie)

The Schillner map of Sprakers. The canal runs across the page while Flat creek runs from bottom to top. The canal crosses the creek on Aqueduct 9 and Enlarged Lock 31 is just to the right. Just above the lock is the boundary line that divides sections 4 and 5. The old line of Clinton’s Ditch can be seen curving across the top and note the outline of the basin. The line of the West Shore railroad runs across the bottom of the map. (Roll 10 Root and Canajoharie- 19_DSC9115.jpg)

The 1910 Blue Line Maps of Sprakers. The large circles note the location of bench-marks, and the map contains many measurements and compass headings. It also makes note of the old Clinton’s Ditch locks, something that the Schillner maps missed. (crop of Set FF BK3_110.jpg)
