Recommends the use of early varieties, selection of cotton seed, thorough cultivation, 

 hand picking of adult weevils from plants in spring, and hand picking of infested squares. 

 Especial emphasis is laid on the fall destruction of the cotton plants either by grazing or 

 cutting and burning, this operation to be followed by deep fall or early winter plowing.

 progeny. Varieties of cotton which seem desirable for planting are discussed, as also fer- 

 tilization, cultivation, and fall destruction of stalks.

 relation to cotton production. A summary is given of experiments with Paris green 

 conducted by the author. Experiments conducted by others are discussed and the author 

 concludes that poisoning is not effective. The desirability of securing legislation to compel 

 fall destruction of stalks is emphasized, as also the need of a State pest commission.
