"The commissioners, acting by appointment under the law of Congress, entitled, 'An act to regulate the laying out and making a road from Cumberland in the State of Maryland, to the State of Ohio,' beg leave to report to the President of the United States, and to premise that the duties imposed by the law became a work of greater magnitude, and a task much more arduous, than was conceived before entering upon it; from which circumstance the commissioners did not allow themselves sufficient time for the performance of it before the severity of the weather obliged them to retire from it, which was the case in the first week of the present month (December). That, not having fully accomplished their work, they are unable fully to report a discharge of all the duties enjoined by the law; but as the most material and principal part has been performed, and as a communication of the progress already made may be useful and proper, during the present session of Congress, and of the Legislatures of those States through which the route passes, the commissioners respectfully state that at a very early period it was conceived that the maps of the country were not sufficiently accurate to afford a minute knowledge of the true courses between the extreme points on the rivers, by which the researches of the commissioners were to be governed; a survey for that purpose became indispensable, and considerations of public economy suggested the propriety of making this survey precede the personal attendance of the commissioners. "Josias Thompson, a surveyor of professional merit, was taken into service and authorized to employ two chain carriers and a marker, as well as one vaneman, and a packhorse-man and horse, on public account; the latter being indispensable and really beneficial in accelerating the work. The surveyor's instructions are contained in document No. 1, accompanying this report. "Calculating on a reasonable time for the performance of the instructions to the surveyor, the commissioners, by correspondence, fixed on the first day of September last, for their meeting at Cumberland to proceed in the work; neither of them, however, reached that place until the third of that month, on which day they all met.
