Pine is good, and almost any cheap wood can be used. Hemlock is not very suitable, unless for the legs. Spruce is cheaper than pine or whitewood, and can be used for economy, but is prone to warp and twist and should be thoroughly nailed.
First make the legs and fasten them together. To do this, take the joist and lay it on two boxes or old chairs (Fig. 38), which you can use temporarily for horses, until you make a pair. See whether either end is cut off squarely. If neither is, mark a line by the square a short distance (perhaps half an inch, according to the condition of the end of the joist) from one end, on one side of the joist. Carry this line around the joist by applying the square to each side successively, and saw off the waste end with the cross-cutting saw. Having one end square, measure from that end 2' 5" and mark a line around the joist as before. Saw this piece off, and using it as a measure (but not as a square), mark and saw off three more pieces. These are for the legs.
