For several years after this first experiment Government workers tested this way of controlling the weevil to be sure that they were right and to find out the best and least costly way of using the poison. Many cotton planters were afraid at first that the expense would be too much for them and they feared that it would not pay to poison their cotton.

Many cotton planters were afraid at first that the expense would be too much for them and they feared that it would not pay to poison their cotton. It was some time before these farmers could be convinced, but we know now that it will pay to use the poison if the weevils are seriously hurting the crop and if the land on which the cotton is growing is rich enough to produce one-third of a bale to the acre when there is no boll-weevil damage. We also. Fig. 6.—The hand dust gun is the smallest kind of machine for dusting cotton plants with calcium arsenate to kill boll weevils. The man who uses it turns a crank which causes a fan to blow the poison dust out of the long nozzle sticking out of the front have learned that if the cotton farmer will see that the poison is put on the plants at the right time and in the right way, a good crop will follow. Poison can not be put on the plants in the right way without proper dusting machines which are specially built for this work. There are several kinds of dusting machines on the market, and perhaps you have seen and used some of them. The hand dust gun (fig. 6) is the smallest kind of dusting machine. As you will see by looking at the picture, the man who uses it walks between the cotton rows and turns a crank on the machine which causes a fan on the inside to blow the poison dust out of the long nozzle sticking out of the front. The man who works the machine must keep the end of the nozzle pointed toward the cotton row while he turns the crank so that the poison will be sure to go on the plants. Hand.
