Plan for bopper-dozer. of a grasshopper that had jumped out. In every case the report was that the insect ''became sick and soon died/' In fact, persons going over fields where a day or so before the hopper-dozer had been at work were impressed with the number of dead grasshoppers scattered about on the ground. An examination showed the presence of coal-oil upon the body. This coal-oil and water is an external irritant, and my observations have been that the mixture is more effective than the pure oil alone. The use of the machine may be best shown by examples. In Ford county this season a large tract of alfalfa was cut, and the locusts at once began moving into a large field of Kafir-corn which had been sown broadcast. The hopper-dozer was drawn back and forth across the end of the corn-field nearest the alfalfa land until a portion of the field about twenty rods deep had been gone over. Here it was appar- ent that then' were very few grasshoppers: or, in other words, the ad- vance line of the locusts' march only extended twenty rods into the Description of Plate Hopper-dozer at work on the ranch of Hon. Thos. H. Ford, Hamilton county. The photograph is taken in alfalfa field, which is being protected for seed crop. Quantity of grasshoppers just taken from pans can be seen in front of pans. This machine was made after instruc- tions of this department, except the 2x4 fourteen-foot extending forward by the side of each mule. These were added by Mr. Ford, and are of great value in steadying the machine. (Photographed l>y Cass.).
