2. The main body of engineers, etc., was ordered to assemble in New York on the 15th May, for which time a vessel was chartered for the purpose of conveying them, with stores sufficient for an expedition of five months and the necessary instruments and camp equipage, to Metis, on the St. Lawrence. The experience of the former season had shown that the country was so poor as to furnish little for the support of a numerous party, and it was believed that even game and fish would be found scarce at the points where supplies would be most needed. It was therefore to be chosen between laying in the supplies in New York or in Quebec, and while the great advantage of conveying all the important instruments by sea turned the scale in favor of the former place, it has been ascertained that the decision was in other respects correct, for the dangers and difficulties of navigating the St. Lawrence might have frustrated altogether, and would certainly have materially delayed, the commencement of the main survey. The sailing of the vessel was delayed, in expectation of the arrival of instruments from Europe, until the 30th of May, when a sufficient supply for beginning the operations arrived. In the meantime Mr. Lally, one of the first assistants, was directed to proceed to Bangor, in Maine, for the purpose of procuring boats and men to manage them. These were obtained and brought down the Penobscot to Castine, where they were on the 8th June embarked in the vessel which carried the rest of the party, and which had orders to call at that port for the purpose. The experience of the previous year had manifested the great superiority of the bateaux of the Penobscot over all other vessels in the navigation of shallow and rapid rivers. The physical energy and enterprise of the boatmen of that river had also been known. It was believed that it was not only essential that a considerable proportion of the laboring force should be American citizens, but that much good would result from emulation between the boatmen of the Penobscot and the Canadian voyageurs. This expectation was in a great degree confirmed by the result, for although it must be stated with regret that it became necessary at an early period to discharge some of the Americans, the remainder were models of intelligence, sobriety, industry, and perseverance, and entered into the work, not with the feelings of hired laborers, but with those of men who felt that the interest of their country was at stake.
