tter that one
need only point out the need for notching the end boards to allow the floor
to touch the sides and back, and the doors when closed. It should be
screwed to the frames, on which it rests, in a few places.

Preserving the Wood.--All outside wood is dressed with stoprot or
creosote, rubbed well into the joints of the boarding.

Felting the Roof.--The felt is cut into 4-foot lengths, and each length
has its ends turned over and nailed to the underside of the roof. The
strips must overlap an inch or two. When the felt is on, dress it with
boiled tar, and sprinkle sand over it while the tar is still liquid.

Fitting.--The two bolts to hold one door top and bottom and the lock are
now fitted, and a couple of hooks screwed into the door frame clear of the
door, to sling a machine from while it is being cleaned or adjusted.

Mounting the Shed.--The shed must be raised a few inches above the
ground, on bricks or other suitable supports. Don't stand it close to a
wall. Air should be able to circulate freely under and all round it.

CUTTING DOWN EXPENSE.

If the cost appears prohibitive, it may be reduced somewhat (1) by using
thinner boards; (2) by reducing the height of the shed by 1 foot. A very
cheap shed, but of course not comparable in quality with the one described,
can be made by using odd rough boards for the outside, and covering them
with roofing felt well tarred.

VIII. A TARGET APPARATUS FOR RIFLE SHOOTING.

The base is a 1-inch board, 18 inches long and 7 inches wide.

The target-holder is a piece of wood 1-1/2 inches square, and a couple of
inches longer than the side of the largest target to be used. To one face
nail a piece of strip lead as weight; and to the parallel face attach, by
means of brads driven in near one edge, a piece of thin wood of the same
size as the face. The free long edge of this should be chamfered off
slightly on the inside to enable the target to be slipped easily between it
and the roller.

The roller is pivoted on two short spindles--which can be made out of stout
wire nails--driven into the ends near the face farthest from the weight.
(See Fig. 26.)

For standards use a couple of the small angle irons used for supporting
shelves, and sold at about a penny each. These are screwed on to the board
2 inches from what may be considered to be the rear edge, and are so spaced
as to leave room for a washer on each spindle between the roller and the
standards, to di
