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.
