Page 51 - ... any. In filling up between the tracks, coarse, large stones must be placed in the bottom in order to provide for drainage, but care should be taken to keep the coarse stone away from the ends of the ties. At the outer ends of the ties the ballast must be sloped off evenly to the sub-grade.

Page 58 - In a wrought-iron or steel bridge the greatest load which can be brought upon it, added to the weight of the superstructure, should not produce a greater strain on any part of the material than five tons, where wrought-iron is used, or six tons and a half, where steel is employed, per square inch.
Page 52 - All necessar3T cross-drains must be put in at proper intervals. Earth taken from ditches or elsewhere must be dumped over the banks, and not left at or near the ends of the ties, but distributed over the slope.
Page 51 - They must be properly and evenly placed, with ten (10) inches between the edges of bearing surfaces at joints, with intermediate ties evenly spaced; and the ends on the outside on double track, and on the right-hand side going north or west on single track, lined up parallel with the rails. The ties must not be notched under any circumstances; but, should they be twisted, they must be made true with the adze, that the rails may have an even bearing over the whole breadth of the tie.
Page 29 - That when animals are carried in cars, boats, or other vessels in which they can and do have proper food, water, space, and opportunity to rest the provisions in regard to their being unloaded shall not apply.
Page 52 - The telegraph poles must be kept in proper position, and trees near the telegraph line must be kept trimmed to prevent the branches touching the wires during high winds.
Page 51 - The cross-ties must be properly and evenly spaced, with ten inches between the edges of bearing surface at joints, with intermediate ties evenly spaced, and the ends on the outside on double track, and on the right-hand side going north or west on single track, lined up parallel with the rails.

Page 52 - Ditches. — The cross-section of ditches at the highest point must be of the width and depth as shown on the standard drawing, and graded parallel with the track, so as to pass water freely during heavy rains and thoroughly drain the ballast and roadbed. The line of the bottom of the ditch must be made parallel with the rails, and well and neatly defined, at the standard distance from the outside rail.
