The Old Pike. Thomas B. Searight
to rake the surface when it becomes uneven by the action of the wheels of carriages. In those parts of the road, if any, where materials of good quality cannot be obtained from the road in sufficient quantity to afford a course of six inches, new stone must be procured to make up the deficiency to that thickness; but it is unnecessary, in any part, to put on a covering of more than nine inches. None but limestone, flint or granite, should be used for the covering, if practicable; and no covering should be placed upon the bed of the road till it has become well compacted and thoroughly dried. At proper intervals, on the slopes of hills, drains or paved catch-waters must be made across the road, when the cost of constructing culverts would render their use inexpedient. These catch-waters must be made with a gradual curvature, so as to give no jolts to the wheels of carriages passing over them; but whenever the expense will justify the introduction of culverts, they will be used in preference; and in all cases where the water crosses the road, either in catch-waters or under culverts, sufficient pavements and overfalls must be constructed to provide against the possibility of the road or banks being washed away by it.
The masonry of the bridges, culverts, and side walls, must be repaired, when it may be required, in a substantial manner, and care must be taken that the mortar used be of good quality, without admixture of raw clay. All the masonry to be well pointed with hydraulic mortar, and in no case must the pointing be put on after the middle of October; all masonry finished after this time will be well covered, and pointed early in the following spring. Care must be taken, also, to provide means for carrying off the water from the bases of walls, to prevent the action of frost on their foundations; and it is highly important that all foundations in masonry should be well pointed with hydraulic mortar to a depth of eighteen inches below the surface of the ground.
As the laws on the subject of this road do not seem to justify a deviation from the original location, you will be careful to confine your operations to the road as you find it located; but, as it is believed that its axis may be dropped without adding much to the expense in those places where its inclination with the horizon exceeds four degrees, you are authorized, under the exercise of a sound discretion, to make this change.
In making your contracts, it must be understood that you are to have the general supervision of their execution, and that it will be your duty to see that all labor and materials (provided for by them) be applied in the most faithful and substantial manner. These contracts must provide in their specifications for all the work that can be anticipated, and should it happen that additional stipulations are afterwards found to be necessary for either workmanship or supplies not originally provided for, the facts must be reported to this department, and, with its approbation, if obtained, new contracts will be made for the additional services and supplies required; and it must be distinctly understood by the contractors that no payment will be made for work not provided for by their contracts.
Mr. L. W. Stockton, of Uniontown, has been engaged on this road and is intimately acquainted with every part of it, as well as with the adjacent country; and, as he has offered his services, you would do well to call upon him and avail yourself of them in any capacity that may seem to you best.
As soon as it can be done, a drawing of the whole road, with details of construction, will be forwarded, to be filed in this office.
You will take up your headquarters at any point on the road where your services may appear to you to be most needed; and, as soon as you shall have completed such an examination of the road as will place you in possession of the information necessary to draw up the specifications to your contracts, you will invite proposals for those contracts through the public prints. These contracts will be closed with as little delay as the interest of the road will allow, when the work will be commenced, and the contracts, together with the proper estimates, forwarded to this office. For the mode of making these estimates, keeping your accounts, and conducting your correspondence with this office, you are referred to the regulations of the Engineer Department.
Captain Delafield has been assigned to the permanent superintendence of the repairs of this road, and has been directed to join you on or before the 1st of October next. You will, therefore, immediately on his arrival, turn over to him these instructions, together with all the papers and public property that may be in your possession relating to the road. As soon as you shall have completed the necessary examinations on the road, you will commence and continue the repairs simultaneously in both States.
You will make application for such instruments and funds as may appear necessary to enable you to execute the foregoing instructions.
I am, &c.,
C. GRATIOT,
Brigadier General.
Cumberland, Md., August 1, 1832.
Sir: I have this evening returned from a general reconnoissance of the road in this State. I find the road in a shocking condition, and every rod of it will require great repair; some of it is now almost impassable. I purpose leaving here to-morrow, on a particular measurement and survey of the road as it is, and the requisites to put it in complete repair.
The object of this communication is to request to be permitted to deviate, according to circumstances, from so much of my instructions as requires the old bed in all cases to be lifted, and the rise in the middle three inches; for there are parts of the road where the top of the old bed is full low, and where it will be more expensive, and less firm, to remove the old bed and fill in with earth, than to bring stone and Macadamize on the top of the old bed to the thickness of nine inches; and there are cases on the sides of the mountains where a greater rise than three inches, such, for instance, as some parts of it now have, which is more advantageous than a less one to confine the water to the gutters in cases of torrents, and thereby preventing a general sweep over the whole road, which would carry off the smallest stuff of a Macadamized road.
The repairs made by Mr. Giesey, about two years since, have the radical fault resulting from having lifted the old road indiscriminately, and not giving sufficient rise to the center for a mountainous country.
I have the honor to be, sir,
Very respectfully, your most obedient,
J. K. F. MANSFIELD,
Lieut. of Engineers.
Gen. Chas. Gratiot, Chief Engineer.
Engineer Department,
Washington, August 9, 1832.
Sir: Your letter of the 1st instant, requesting permission to deviate, according to circumstances, from so much of the instructions of the department to you, on the subject of the repairs of the Cumberland Road, as requires the old road in all cases to be lifted, and the rise in the middle to be made three inches, has been under consideration, and I have to inform you that this permission cannot be granted.
In withholding the sanction of the department to any deviation from the prominent features of your instructions on the subject of these repairs, it may, perhaps, be proper to state, for your information, the views of the department on this subject.
By referring to the report of Mr. Weaver, a printed copy of which you have in your possession, who made an examination of the Cumberland Road in 1827, you will perceive that the mode of constructing it was that of digging a trench, or of sinking the bed of the road below the natural surface of the ground; that this trench was filled with large stones, and that these were covered with stones a size smaller, and so on. By this construction, it was intended that the weight of the carriages passing over the road should be supported by the large stones, and that the smaller stones were only intended to present an even surface for the easy passage of vehicles over it. The great objections to this construction are, that the bed being lower than the surface of the ground on each side, the ditches can hardly ever be sunk sufficiently deep to intercept the passage of water from the ground adjacent to the road to the ditch or trench in which the road is made; this water, by keeping the bed constantly wet, would cause the heavy stones of the first layer to sink into the ground, and thus break up the surface of the road, and allow the free passage of water through the covering itself. In the winter, the frost acting upon the bed, rendered wet by the free passage of water to it in every direction, would heave the stones to such a degree that the
