Mr. Purcell reports to the Board of the Chesapeake and Ohio Canal Company that the road being at the site now chosen will occasion an increased cost to the Canal Company of upwards of $16,000. It is very desirable to avoid this state of things, for, as their charter claims precedence, it would necessarily create a demand upon the government commensurate with the injury sustained. Major Eaton, president of the Canal Company, will direct Mr. Purcell, the engineer, to proceed forthwith to Cumberland, with you, to ascertain the best mode of making the location by which to avoid any injury or increased expense to the Canal Company. You are instructed to confer freely with Mr. Purcell, holding the object suggested steadily in view, and give such direction to the location of the road as may best attain this object. This done, you will forward a plan of the route agreed on, and a minute detail of everything, particularly what increased expense to the Canal Company will probably be occasioned. On receiving your report, the case will be considered here, and you be advised immediately of the course to be pursued. Very respectfully, &c., &c., By order: WM. H. C. BARTLETT, Lieut. and Assistant to Chief Engineer. Capt. R. Delafield, Corps of Engineers, Uniontown, Pa. * * * * * PHILADELPHIA, July 26, 1833. _Sir_: The order of your department of the 16th instant was received by me at Cumberland, and its injunctions forthwith carried into effect. The communication of the 20th has since been received, explanatory of that order. In relation to locating that part of the National Road that might probably interfere with the Canal Company, measures were taken to procure from the Company such information as would enable me to locate the road without coming in contact with any part of the Canal route; and, so far as the information was furnished, I have endeavored so to do. I enclose copies of the letter and information received from the president of the company, in reply to a request for such information as would enable me to "ascertain at what point the Chesapeake and Ohio Company contemplate erecting their dam across Wills creek, and to what height it will be raised above low water. The information desired is for enabling me to locate the bridge for the road at a point, and elevate its arches to such a height that the interest of the Canal Company will not be effected; and that I may at the same time, fulfill the objects contemplated by the law authorizing the new location."
