-- MARKING THE LINE. Monolithic monuments will be placed on the boundary at the following places: Near the Northern Pacific Railway, near the Great Northern Railway, and near the north bank of the Kootenai River. These monuments are to be 6 feet long and 10 inches square, minimum dimensions, and are to be placed in a truly verti­ cal position, set 3 feet in the ground and with their'faces directed to the cardinal points. They are to be of undressed stone, except for a space sufficient to cut the words "Idaho" and "Montana" on the west and east sides, respectively, which will be dressed smooth, and tho letters shall be 2 inches high, of proportionate width and of the style known as Egyptian. The same kind of monuments will be placed on the line at the international boundary and at the summit of the Bitterroot Mountains if it shall be found practicable to transport them in one rnass, otherwise they will be prepared in the quarry in every respect similar to those mentioned above and will then be sawed into sections of such size as to be readily transported on pack mules to their destinations. They will then be firmly and securely cemented with Portland cement and established in the same manner as the other stone monuments. The monument on the international boundary in addi­tion to having the inscription "Idaho" and "Montana" on the west and east sides, respectively, will have " Canada" inscribed on the north. Intermediate between the stone monuments above described will be placed at prominent summits, road, trail, or stream crossings, at distances not exceeding a mile apart, and intervisible whenever possible, wrought-iron posts 6 feet in length, 3 feet of which shall be above ground and 3 feet below the surface, with a brass cap similar in general design to the standard iron posts used by the United States Geological Survey. The cap surmounting the post will be inscribed as below, the line cut on the cap being coincident with the boundary line:

IDAHO BOUNDARY

LINE MONTANA

Under each post will be placed a stone marked with charcoal or a vial filled with ashes. It is assumed that generally a soil surface for the insertion of the stone or iron posts can be found sufficiently near the points it is desired to establish the monuments. If, however, the exact point should fall on rock at the international boundary or the summit of the Bitterroot Mountains, a hole will be chiseled in the rock to a depth of about 8 inches and a little larger than the base of the monument. Into this hole the monument will be firmly cemented with the best Portland cement. If the point for the location of one of the iron posts should fall on a rock surface, a copper plug similar to that used by the United States Geological Survey will be cemented in the rock and a truncated conical mound of stone, not less than 2£ feet high and 5 feet broad, will be- placed to the north of the point at a distance of 4 feet from it. The copper plug will be stamped as follows: MONT.

IDA.

and will be properly oriented.

When suitable bearing trees are found within a distance of 100 feet of a stone monument or iron post, they must be marked on the side facing the corner in the manner prescribed in the manual for special corners. In addition, each iron post will be witnessed, when possible, by mounds of earth or stone, one in Idaho and one in Montana, the material for the mounds to be taken from pits, one north and one south of the post, dug crosswise of the line. The pits will be 3 feet east and west, 2 feet north and south, and 1 foot deep, and their centers, as well as the centers of the mounds, will be 4 feet from the center of the iron post.
