English: From original book: "In the ordinary shingled roof a light boarding is first nailed to the rafters, and upon this the shingles are secured in close courses. The shingles are always split, and are very thin, — being about the thickness of an ordinary octavo book-cover, and not much larger in size, and having the same thickness throughout. They come in square bunches (fig. 61, A), each bunch containing about two hundred and twenty shingles, and costing about forty cents.
Bamboo pins, resembling attenuated shoe-pegs, are used as shingle-nails. The shingler takes a mouthful of these pegs, and with quick motions works precisely and in the same rapid manner as a similar class of workmen do at home. The shingler's hammer is a curious implement (fig. 61, B, C). The iron portion is in the shape of a square block, with its roughened face nearly on a level with its handle. Near the end of the handle, and below, is inserted an indented strip of brass (fig. 61, b). The shingler in grasping the handle brings the thumb and fore finger opposite the strip of brass; he takes a peg from his mouth with the same hand with which he holds the hammer. and with the thumb and forefinger holding the peg against the brass strip (
fig. 62), he forces it into the shingle by a pushing blow. By this movement the peg is forced half-way down; an oblique blow is then given it with the hammer-head, which bends the protruding portion of the peg against the shingle, — this broken down portion representing the head of our shingle-nail. The bamboo being tough and fibrous can easily be broken down without separating. In this way is the shingle held to the roof. The hammer-handle has marked upon it the smaller divisions of a carpenter's measure, so that the courses of shingles may be properly aligned. The work is done very rapidly, — for with one hand the shingle is adjusted, while the other hand is busily driving the pegs."
