Other Early Builders of Gerrish-style Canoes
Although we have convincing evidence that Gerrish built the earliest known birch-built canvas canoe in 1875, it would be five years before a description of one of his canvas canoes appeared in the local news. (Below. Please excuse my search highlighting!)

(Local Matters, Bangor Daily Whig and Courier, 20 may 1880)
It is interesting that the canoe order mentioned in the description is from Sebec Lake. We now know that his first canoe was being used there by Ansel Crockett, so the sale may have been the result of a direct encounter with that canoe. These direct encounters with actual canoes seems to have been the primary driver for sales during this period at this time.

(The Industrial Journal, 4 April 1886, Newspapers.com).
Apparently, Gerrish was already experimenting with other canvas boats in 1880. The "Queer Boat" described below sound like it may have been and early Peapod with a special twist.

(A Queer Boat, Commercial, 12 June 1880, p1.)
During the intervening years between Gerrish's first birch-built canvas canoe and the two canvas boats described in 1880, the canvas canoes of two other Maine builders were mentioned in surviving documents . The earliest birch-built canvas canoe described in the literature was built by a "Yankee" on Moosehead Lake in 1878.

Neither the name nor the location of the “Yankee” builder are included in this description, so some have attributed this canoe to Gerrish, which in my opinion is highly unlikely. Although many of Gerrish's canoes would end up at Moosehead Lake, there is no evidence that he built canvas canoes at the Lake. He had already moved to Bangor and was likely busy setting up his shop at 18 Broad, which opened that very year, 1878. A much more likely suspect for this "Yankee" is George Kirkpatrick of Greenville. A column called “Do you Remember?” from 1931 includes the following query, "When George Kirkpatrick built the first canvas canoe used on Moosehead?" (Do you Remember, Piscataquis Observer, 11 June 1931). Unfortunately, the column did not provide answers, but I suspect the canoe described above is the first canvas canoe. on Moosehead Lake. It is also likely that the canoe builder
George Patrick of Greenville described in 1885 was in fact
George Kirkpatrick, and that the author may have confused him with a guide named George Patrick from Greenville who appears in the literature around that time.
(Piscataquis, Bangor Daily Whig and Courier, 18 July 1885)
Kirkpatrick is listed in the New England Business Directory as a canoe builder between 1887-1890 and the Maine State Yearbook 1888-1894. Just before his death in 1893 Kirkpatrick was described as follows,

(Sun Journal_Lewiston Maine_20 July 1893.)
It appears that Kirkpatrick's estate was sold at auction in 1895. I have not looked at town records, but it sounds like he had quite a bit of land.
The other builder of birch-built canvas canoes mentioned was Jock Darling, whom a "Sport" visited at the end of fishing trip in September of 1879 and found him building a canvas canoe.

(Syseledobsis and Passadumkeag, Forest and Stream, 18 May 1880 )
A long and interesting article on
Nicatous Lake and Its Surroundings, points out that Darling spent a lot of time at his Camp Nicatous where "there are plenty of canoes on hand, Mr. Darling employing his leisure time in building them, using either birch or canvas as may be desired."
Although these canoes would become popular among indigenous builders and continue to be built into the 1920s in some areas, there are only two additional known "Yankee" builders of birch-built canvas canoes; Hilbert Colson, at Great Pond, Hancock County who built canvas canoes "like a birch" (Bark Canoes, Forest and Stream, 30 September 1886 p. 196) and B. N. Morris at Veazie, who built three canvas covered canoes "after the principle of the birch-bark canoes, of loose ribs and planking with a tight skin of canvas" in 1887 before adopting the method of the solid-planked shell. (Morris, B. N., Morris Canoes, The Fort Hill Press, Samuel Usher, Boston, ca1907, p.2.)
I have included a map, to which I have added the known "Yankee" builders of birch-built canvas canoes, their locations, the date they started building. "Canvas Canoes" claims that Gerrish's first canvas canoe was "novelty that drew a great deal of attention" and the dates and locations of the builders could certainly support the conclusion that subsequent builders were inspired by Gerrish's canoe (or the canoe of another earlier builder), but the actual transfer of information and knowledge about the canoes, if any, remains unknown.
