The original of this design was actually made up in white wood, stained and finished to harmonize with black walnut furniture; but it may be made up in oak, ash, cherry, or any of the common woods used for furniture. For one bookcase the stock required is as follows, the sizes allowing for finishing to the dimensions as given in the drawing: For the ends, two pieces 7/8 inch × 10-1/4 inches × 4 feet 2-1/2 inches; for the short shelves, three pieces 7/8 inch × 10-1/4 inches × 3 feet 1 inch; for the long shelves, two pieces, 7/8 inch × 10-1/4 inches × 3 feet 5 inches; for the base pieces, two pieces 7/8 inch × 6-3/4 × inches × 3 feet; for the keys, one piece 7/8 inch × 7/8 inch × 1 foot. In addition to this there should be two dozen No. 10 round-headed blued screws, and one half dozen 1-1/2 inch No. 10 flat headed blued screws.
The tools needed are as follows: Rip saw, cross cut saw, back saw, compass, jack-plane, smoothing plane, block plane, spokeshave, try square, steel square, rule, knife, hammer, mallet, screw-driver, 3/4, 1/2, and 3/16 inch bits and bitstock, and 1/2 and 3/4 inch chisels, gauges, and sand-paper.

_Construction._--All the stock should be jointed, planed to width, and smoothed with sand-paper. The two end pieces should be squared to length, the top corners rounded, and the curve at the bottom cut as shown in the drawing. Care should be exercised in sand-papering not to round the edges. The correct spacing for the shelves should then be marked off on the end pieces and squared across, care being taken to have both ends spaced alike. To do this plane the ends together, with their edges flush; and, beginning at the bottom, measure off each of the spaces with correct allowance for the thickness of the shelf and mark these spaces across the edge. Then, separate the end pieces and with the marks on the edges as a guide, square across each of the end pieces on the inside and mark with a knife. In allowing for the thickness of the shelves it should be remembered that the stock, though originally 7/8 of an inch in thickness, has been planed and sand-papered, some of the shelves perhaps having been finished down more than others. It will therefore be necessary to measure and allow for the thickness of each shelf separately.
