This Simple Periscope Is Useful Both for Play and Practical Purposes
It consists of a square box, 18 in. long, open at the ends. It is 3¹⁄₂ in. wide and made of wood, ³⁄₈ in. thick. A mirror is fitted at an angle of 45° near one end of the box or tube, as shown in the sketch. The front of the mirror is opposite a three-cornered opening in the box which extends across one side. The opposite end of the tube is also fitted with a mirror in the same manner, except that the front of the mirror faces to the opposite side of the box at which there is also an opening. In using this device, the user sights from the point indicated by the eye. The image is reflected in the mirror at the top and thrown onto the lower mirror, where it may be seen without exposing the head above the level of the lower opening. It is this application of reflection by mirrors that makes it possible for soldiers to see distant objects without exposing themselves to fire, by the use of the periscope.
Trap for Coyotes
By Drawing on the Wire the Coyotes were Brought under Control and Forced from Their Lair
Two coyotes, resisting capture in a hole under a lava ledge, were hauled forth quickly when the device shown in the sketch was used, after other means had proved ineffective.
I made a snare of baling wire and attached it to a pole, 6 ft. long, running the wire down from the loop to the end of the handle. The loop was made about twice the size of the coyote’s head, and, by drawing on the wire at the handle, the animals were placed under control and held at a safe distance.—Contributed by Milton Barth, Geyserville, Cal.
