Paragraph 47. Hemlock is a wood of light reddish-green color, free from rosin pockets, but of very coarse fiber and usually cross-grained. Although very splintery and frequently defective on account of wind shakes, yet when sound it is a stiff and rather strong timber. It shrinks and warps badly and is not very durable, however it is used considerably for rough framing and for sheathing. The increasing cost of the better woods has forced hemlock into pretty general use for rough work in many localities.
