��An Accident Chart Showing Injuries to Miners

THE illustration is from a diagram pre- pared by the Bureau of Mines for the use of surgeons and hospitals in the mining districts in the selection of necessary sup-

plies. The diagram shows that practically 30 per cent, of accidents in coal mines re- sult in injuries to the legs and about 14 per cent, to the hands, while accidents to other parts of the body are shown in rel- ative percentages.

��A Rabbit Trap Made of Ordinary Drain Tile

A CLEVER plan for catching rabbits is recommended by the Department of Agriculture. It is a trap which catches the rabbits alive, and almost any boy can con- struct one quickly.

The materials required consist of a 12-in.

���The tiles are set in the earth so that a hiding-place is made for the rabbit

sewer-tile with a 6-in. side outlet and two lengths of 6-in. tiles. The long end of the larger tile is set downward in the ground so

��that the small side outlet is below the sur- face, as shown. The two small tiles are connected with the side outlet so that the opening will extend out to the surface.

The tiles are well covered with soil to exclude all light, and a close fitting cover is placed over the upper end of the large tile. The open end of the small tile may be sur- rounded with a few small stones and brush to make it inviting to the rabbits.

The rabbits are free to pass in and out of the dens thus made. When they are located in one of them it is an easy matter to close up the entrance and take them out of the large tile by raising the cover. Such traps are especially, suited to open places or on prairie lands where rabbits cannot find natural hiding-places.

��A WaU Book Shelf of "Built-in" Appearance

WHILE almost any kind of wood can be used in the making of this book shelf, it is well to select the kind of wood that will match with other pieces of furni- ture, or the finish of the room. If made of the same wood as the doors and casings it will have a "built-in" appearance and there will be no abrupt contrast with articles of furniture. The finished shelf is shown in Fig. I. The material list is as follows:

1 base, 2 ft. long, 6}>^ in. wide and ^ in. thick

2 facing pieces, 6 in. long, 5^^ in. wide and

^ in. thick I top back rail, 123^ in. loi^ i/^ in. wide and ^ in. thick

1 bottom back rail, 12)^ in. long, i in. wide

and % in. thick

2 top end rails, 6 in. long, ij^ in. wide and

^ in. thick 2 bottom end rails, 6 in. long, i in. wide and

^ in. thick 2 back uprights, 10 in. long, iJ4 in. wide and

^ in. thick 2 brackets, 6 in. long, 2 in. wide and j^ in.

To start the work, begin with the base, the plan of which is shown in Fig. 2. If the material is purchased from a mill the pieces can be ordered cut to dimensions, planed and sanded, which will cover most of the hard work. The outside corners of the base are slightly rounded as shown. The bracket pieces and the back uprights are next in order of construction. The lower ends of the uprights are cut pointed and set in the back edge of the base as shown in Fig. 3. The joints for the rails are shown in Fig. 4.

The facing pieces have an ornamental
