Along the side of this inclosure, next to the wall, is a fixed desk of proper height for a man standing, say 41 inches. It should be 24 inches wide and incline to the front about 2 inches in its width. Upon it, and in the corner between the two windows, should be placed a suitable pigeon-hole case, not over 24 inches high and 8« inches deep. The top, bottom, and sides are of ⅞-inch white pine and the partitions are of «-inch stuff. This, with the desk, should be protected by two or three coats of shellac varnish. This case will be used for holding such blanks, slips, memoranda, and similar papers as are in use. Proper space should also be provided for the necessary books relating to the carpenter work, boxing, skidding, shipping, and similar work.
At the left-hand side, and between the window and the partition, there should be fixed to the brick wall a board of the same height as the pigeon-hole case for convenience in hanging filing clips and for similar purposes. Beneath the desk should be two drawers, about 5 inches deep, 24 inches from front to back, and 30 inches wide, and provided with locks. Such an arrangement of desk, pigeon-hole case, drawers, etc., is shown in Fig. 153, which will give a general idea of its appearance and usefulness as well as of its economical construction.
The particular description here given of such fittings as these will apply to the design, arrangement, and construction of similar cases, racks, shelves, and other divided spaces necessary in many other parts of the plant, and we shall be well repaid for the time spent in carefully designing them to meet the special conditions and objects for which they are to be used, and shall often be enabled thereby to save quite a percentage of the time of the employees using them. They may be constructed by any good carpenter and will be in many respects the best as well as the most useful.

Adjoining the foreman's office and opening out of it is a similar inclosure, to be used as a storeroom for the carpenter shop and to hold such articles as may be much more conveniently kept here than in the principal storeroom, in the office portion of the plant, to be drawn in small quantities as needed.
Against the wall is a case containing a row of bins for holding nails, spikes, etc. They are constructed of sufficient dimensions to hold a liberal supply of each size of nails and spikes, and the front board is made quite narrow, not over 6 inches high, to facilitate the removal of the contents. Above this row of bins is a case for lag screws, etc., containing thirty-five boxes, this being amply sufficient for all the different sizes usually needed. The width of this case is determined by the distance apart of the two windows between which it is located. At the left of this case, standing on top of the bins, and in front of the window, should be a small counter scale for weighing such articles as may be used or issued and are to be accounted for by weight. A perspective view of this case and the row of bins is given in Fig. 154.

On the opposite side of the storeroom is a somewhat similar case for holding nuts, washers, etc., in the bins, and having above it a case with forty-two compartments for machine bolts, carriage bolts, etc. A perspective view of this case is given in Fig. 155. Both of these cases are made of ⅞-inch pine and painted. The top of the bins is 24 inches from the floor. That shown in Fig. 154 is 6 feet high, but the one shown in Fig. 155 is limited to 5 feet so as not to unduly obstruct the light. The base of the bins is 18 inches wide. The depth of the upper cases is 8« inches. In the construction of cases of this kind it is well to remember that they may be made of an ordinary quality of pine commonly called "box boards," planed on both sides. The horizontal boards or shelves are first put in, the ends resting on cleats screwed to the uprights at the ends of the case. The upright partitions are cut to the correct length on the cutting-off saw, set in place and "toe nailed" in front, and nailed through the back. All the shelves and upright partitions should be ⅛ inch narrower than the uprights at the ends, while the top should project « inch at the front and ends. The bins may be built in place, nailed to the floor, but it is sometimes desirable to have such fittings built separate and set in place when completed, so that they may be moved, in case it should be necessary to do so, without partially or wholly destroying them.

The location of the piles of lumber is indicated by dotted lines, and the capacity of the space is marked in each case. At the side of the yard track entering the carpenter shop is a cutting-off saw. This may be one with a sliding table, upon which the lumber to be cut is placed and moved toward the saw. But for rapid work a swinging saw, pivoted overhead, and quickly moved in an arc across the piece of lumber, is preferable for the ordinary rough work called for in the carpenter shop. Of course, such a saw must be carefully protected so that the careless use of it may not be dangerous to the workmen.
