The indirect course of the road now traveled, and the frequent elevations and depressions which occur, that exceed the limits of the law, preclude the possibility of occupying it in any extent without great sacrifice of distance, and forbid the use of it, in any one part, for more than half a mile, or more than two or three miles in the whole.

The expense of rendering the road now in contemplation passable, may, therefore, amount to a larger sum than may have been supposed necessary, under an idea of embracing in it a considerable part of the old road; but it is believed that the contrary will be found most correct, and that a sum sufficient to open the new could not be expended on the same distance of the old road with equal benefit.

The sum required for the road in contemplation will depend on the style and manner of making it; as a common road cannot remove the difficulties which always exist on deep grounds, and particularly in wet seasons, and as nothing short of a firm, substantial, well-formed, stone-capped road can remove the causes which led to the measure of improvement, or render the institution as commodious as a great and growing intercourse appears to require, the expense of such a road next becomes the subject of inquiry.

In this inquiry the commissioners can only form an estimate by recurring to the experience of Pennsylvania and Maryland in the business of artificial roads. Upon this data, and a comparison of the grounds and proximity of the materials for covering, there are reasons for belief that, on the route reported, a complete road may be made at an expense not exceeding six thousand dollars per mile, exclusive of bridges over the principal streams on the way. The average expense of the Lancaster, as well as Baltimore and Frederick turnpike, is considerably higher; but it is believed that the convenient supply of stone which the mountain affords will, on those grounds, reduce the expense to the rate here stated.

As to the policy of incurring this expense, it is not the province of the commissioners to declare; but they cannot, however, withhold assurances of a firm belief that the purse of the nation cannot be more seasonably opened, or more happily applied, than in promoting the speedy and effectual establishment of a great and easy road on the way contemplated.

In the discharge of all these duties, the commissioners have been actuated by an ardent desire to render the institution as useful and commodious as possible; and, impressed with a strong sense of the necessity which urges the speedy establishment of the road, they have to regret the circumstance which delays the completion of the part assigned them. They, however, in some measure, content themselves with the reflection that it will not retard the progress of the work, as the opening of the road cannot commence before spring, and may then begin with marking the way.

The extra expense incident to the service from the necessity (and propriety, as it relates to public economy,) of employing men not provided for by law, will, it is hoped, be recognized, and provision made for the payment of that and similar expenses, when in future it may be indispensably incurred.

The commissioners having engaged in a service in which their zeal did not permit them to calculate the difference between their pay and the expense to which the service subjected them, cannot suppose it the wish or intention of the Government to accept of their services for a mere indemnification of their expense of subsistence, which will be very much the case under the present allowance; they, therefore, allow themselves to hope and expect that measures will be taken to provide such further compensation as may, under all circumstances, be thought neither profuse nor parsimonious.

The painful anxiety manifested by the inhabitants of the district explored, and their general desire to know the route determined on, suggested the measure of promulgation, which, after some deliberation, was agreed on by way of circular letter, which has been forwarded to those persons to whom precaution was useful, and afterward sent to one of the presses in that quarter for publication, in the form of the document No. 3, which accompanies this report.

All which is, with due deference, submitted.
