. Control of field rodents in California. Rodents; Mammals. FORMULA 5 Cut Baits for Pocket Gopher Cut baits of sweet potatoes, carrots, or parsnips 4 quarts Strychnine (powdered), either alkaloid or sulfate 1/4 ounce Cut the vegetables into pieces about i/2 X \/2 x 1]A inches. With a pepperbox or other sifting device dust the strychnine on the baits, a little at a time, meanwhile turning them over and over, until all are evenly coated. Put the baits in a covered container and use as soon as pos- sible. Label, plainly, both the bucket and the sifter: POISON. FORMULA 6 Poisoned Raisins or Prunes for Pocket Gopher With a slender knife point insert a few crystals of strychnine sulfate into the center of each bait. The prunes should first be soaked for about 2 hours in water; if dried thoroughly after being poisoned, they will keep; such baits can be stored in a bottle or can and must be plainly marked POISON. Baits of any kind are placed in main runways by use of a special probe (fig. 15), with which burrows can easily be located and baits inserted with a mini- mum of disturbance. The probe can be made by a blacksmith. The main shaft is of 1/2-inch iron pipe, 33 inches long. A bluntly conical point of solid metal of the same diameter as the pipe is welded to one end, and to the opposite end, a 12-inch length of 3^-inch steel rod. The free end of the rod is forged to make a slightly larger carrot-shaped tip about i/2 inch in diameter at the base, tapering to a sharp point. In loose or sandy soil the rod tip may be slightly larger; for hard earth the slight enlargement near the tip may be omitted. The side arm, 6 inches long, has a collar (and set screw) by which it is clamped to.
