The concentration of this market and its considerable distance from New York City at a time when transportation conditions were still relatively primitive must have created many problems in distribution. Moreover, the serious threat to the important Canadian market imposed by White and Moore, although eventually settled by compromise, must have emphasized the vulnerability of this territory to competition. It was also probable that the office in lower Manhattan--at 106 Franklin Street after May 20, 1862--was found to be increasingly congested and inconvenient as a site for mixing pills and tonics, bottling, labeling, packaging and shipping them, and keeping all of the records for a large number of individual small accounts. A removal of the manufacturing part of the business to more commodious quarters, adjacent to transportation routes, must have been urgent. But why move to as remote a place as Morristown, New York, beyond the then still wild Adirondacks? It is obvious that this location was selected because the company already had an office and some facilities in Brockville, Canada West. William H. Comstock must have first become established at Brockville, after extensive peregrinations through Canada West, around 1859 or 1860. During the dispute between A.J. White and Comstock & Judson, Blakely, the aggressive Canadian agent, had written to White, on September 1, 1859, that he had heard from "Mr. Allen Turner of Brockville" that the Comstocks were already manufacturing Dr. Morse's Indian Root Pills at St. Catherines. Evidently the Comstocks thought of several possible locations, for on July 2 of the following year Blakely advised his principals that the Comstocks were now manufacturing their pills in Brockville. Two years later, in November 1862, when Blakely sued William H. Comstock for the forgery of a note, the defendant was then described in the legal papers as "one Wm. Henry Comstock of the town of Brockville Druggist." And in July 1865, Comstock was writing from Brockville to E. Kingsland, the bookkeeper in New York City, telling him to put Brenner--the bearer of the letter--"in the mill." Comstock had apparently taken over an existing business in Brockville, as receipts for medicines delivered by him describe him as "Successor to A.N. M'Donald & Co." Dr. McKenzie's Worm Tablets also seem to have come into the Comstock business with this acquisition.
