Returning to what may strictly be considered purchased parts, the following arrangement of them will be found to be convenient and practical, both for proper storing and for issue. Machine screws should be kept in the original gross packages, on shelves not necessarily over 6 inches in width, and for the smaller sizes 5 inches apart; for the larger sizes about 9 inches apart. For eighty sorts, say from ¬ inch 6-32 to 2 inch 24-16, and in both round and flat heads, there will be about twenty linear feet of shelving required, exclusive of vertical supports. Set screws are also kept in the original packages on similar shelves. Thirty-four sorts, from ¬ inch × ⅜ inch to ¾ inch × 2« inches, of both oval and cupped points, will require about twenty linear feet of shelving, exclusive of vertical supports, the shelves to be placed the same distance apart as for machine screws.

While the set screws average larger than the machine screws there are only fifty in a package, against one hundred and forty-four machine screws. Set screws with V-points, if they are of small sizes, may be kept in the original packages, but if of larger sizes, as for shafting hangers, they are best stored loose in bins. Gib screws, being of the smaller sizes, should be kept in packages or boxes. Round head and hexagon head cap screws of small sizes, say ¬ × 1 inch to 7-16 × 1¾ inch, should be kept in packages, on shelves, and will occupy about the same space as set screws. The larger sizes should be kept in bins holding about five hundred. In arranging shelf space for machine, cap, and set screws it is assumed that there will be at least three packages of each size on hand, which will be sufficient for all ordinary purposes. Special screws are usually made in large lots and are more conveniently kept in bins.

Belting may be placed under the bench at the end of the room. The rolls should be set on edge, between vertical supporting boards, and kept in place by a strip 3 inches high, placed on the floor in front of the rolls. In issuing belting the roll remains in place and the portion taken off is stretched along the floor and measured to the length required.

Miscellaneous hardware should be kept on shelves, and as it is seldom called for, the higher shelves will be the proper place.

Should the amount of purchased parts be larger in proportion than is here arranged for, the door leading into the general office may be omitted, thus gaining room for one more case and making one more alcove, and a door be cut through into the hall from the space inside the rail. This would add about 15 to 20 per cent to the storage capacity of the room.

The desks provided in these rooms should be a fixed top about 44 inches from the floor. Twenty-four inches wide will be ample. The top should be inclined to the front about 1 inch to the foot. Drawers provided with locks are fitted under this top, and below the drawers should be three shelves 12 inches wide, the first 8 inches from the floor and the others 8 inches apart. These will be convenient for storing books, blanks, etc. The space under the counters should also contain similar shelves, but these should not contain articles of regular issue to the shop.

The stock used for building bins and cases should generally be ⅞-inch pine. The divisions in the file case and in the sheet metal case need be only « inch thick. It is well to paint all these fittings quite a light lead color, as it is a good wearing color, and should not be so dark as to interfere with ample light. The partitions may be of the same tint up to a line 5 feet above the floor, and above that, including the ceilings, white. The same colors will be proper for the tool-making department.

From the descriptions given in this work and the dimensions mentioned ordinary carpenters should be able to construct any of these fixtures in a creditable manner. The author has supervised the construction of every form shown herein and can testify to their convenience and efficiency as well as the economy of the construction shown and described.
