screwed on the board. The top board is weighted with a 

 brick, a flat stone or a chunk of wood. Before setting the 

 trap, put the foot firmly upon the part of the mole track upon 

 which the trap is to rest, for the purpose of obstructing the 

 run. Also press the teeth down into the soil, so there will be 

 no obstruction when the trap is sprung. Then set the trap as 

 shown in cut. The paddle part of the trigger should touch 

 the surface of the ground exactly over the line of the track. 

 The mole finding his accustomed path filled up, at once begins 

 to re-open it, and heaving up the surface, springs the trigger, 

 and is pierced by the teeth on one side or the other." — Popular

Self-Acting Animal Gun. — (Fig. 17, page 179.) A device 

 invented and manufactured by Foreman Brothers, BidwelV s 

 Bar, California. 



Home-Made Hydrant. — (Fig. 18, page 178.) This device 

 can be used where water works do not exist. " Take a large 

 barrel, place it on the left of some out-building at least 21 feet 

 above the point of application, as each 2 T V feet of elevation 

 gives us one pound, and we want to get a pressure of not less 

 than 10 pounds per square inch. To fill the barrel we want a 

 force-pump. This consists of a simple brass cylinder (iron 

 would rust, and get rough inside) with a plunger. The lower 

 end is reduced, and with a ^-inch nipple screwed to a 3^ -inch 

 T having a valve at each side, both facing the same way. 

 From the entrance side of the valve, carry a line of pipe to 

 the cistern, letting the lower end reach within one inch of the 

 bottom ; run the other end into the line of pipe leading from 

 the bottom of your barrel to your garden. A is the cylinder, 

 made of brass, to be had at any brass foundry or machine 

 shop, together with the reducer at the bottom; B is the Y^- 

 inch T, and C the pipe, which can be had at any machinists' 

 supply shop at a price not exceeding five cents per lineal foot ; 

 D D are the check valves, can be had for about 25 cents each, 

 E is the crank which alternately raises and depresses the pis- 

 ton of the pump. To get the motive power, we harness up 

 "Old Dog Tray," get him up over the bridge F, and it won't 

 take long before he will learn to work it the same as a tread- 

 power from the steps H H. These must be made low, and 

 near enough to require only small steps. So few have been 

 able to construct such a machine, not from the lack of me-
