The arrangement of the fibers whichgo to make up a piece of timber give to it certaincharacteristics which are described as different conditions of thegrain of the wood, the word grain being used as a substitutefor the word fiber. Thus across the grain, means at rightangles to the general direction of the fibers; along the grain,means parallel to the direction of the fibers. In like mannerwoods are said to be fine grained, coarse grained, crossgrained, or straight grained, these terms being used to indi-cate the relation of the fibers to each other and to the generaldirection of the growth of the tree. The wood is said to be finegrained when the annual rings are relatively narrow so as to showa large number of fine lines on a cross section of the log, and it issaid to be coarse grained when the rings are wider so as to show asmaller number of coarser lines on the cross section of the log. Woodswhich are fine grained are generally harder and denser than those. Fig. 2. Diagram of Pine Wood Fibers Magnified 17 8 CARPENTRY If!»
