For destroying prairie dogs, Professor Lantz says that out of thousands of suggestions nothing has been found more effective than strychnine poison and carbon bisulphide. Following are directions for preparing and using the strychnine: “Dissolve one and a half ounces of strychnine sulphate in a quart of hot water. Add a quart of syrup--molasses, sorghum, or thick sugar and water--and a teaspoonful of oil of anise. Thoroughly heat and mix the liquid. While hot pour it over a bushel of clean wheat and mix completely. Then stir in two or more pounds of fine corn meal. The quantity of corn meal needed will depend upon the amount of extra moisture present. There should be enough to wet every grain of the wheat and no more. Care should be taken that there is no leakage from the vessel in which the wheat is mixed. Let the poisoned grain stand over night, and distribute it in the early morning of a bright day. Use a tablespoonful of the wheat to each hole occupied by prairie dogs, putting it near the mouth of the burrow in two or three little bunches. Do not put out the poison in cold or stormy weather. It will keep for a considerable time, and is much more effective after a cold period, as the animals are then hungry and eat the grain readily. A bushel of wheat should poison 1000 to 1200 holes. An excellent substitute for the oil of anise in this formula can be made by soaking two ounces of green coffee berries in the whites of three eggs. Let this stand for about twelve hours, and use the liquid instead of anise oil.” A tablespoonful of carbon bisulphide, upon some such absorbent material as cotton, dry horse manure, or a piece of corn-cob, and rolled into the burrows, is effective. It is best immediately to cover the hole with a sod and stamp down firmly. GRASSHOPPERS Grasshoppers are a source of no little loss to alfalfa growers in some parts of the West. They usually do their greatest damage to the season’s second crop, the young not being very destructive to the first. The best remedy, or rather prevention, is deep disking in April and then harrowing to destroy the eggs.
