Concerning pruning there is much }et to he learned, 

 whether it shall be done early or late, high or low. and for how 

 many years the plant will thrive under such treatment. All that 

 we know is that it is necessary to prune occasionally in order to 

 control the size and shape of the plants and to maintain the 

 quality of the lint. From experiments in 1911 we conclude that 

 with us fall pruning is imperative in order to allow proper de- 

 velopment of the plant during the winter months when moisture 

 is plentiful. Plants allowed to bear during this time, then 

 pruned abotit ]\larch first, made plants only about two-thirds as 

 large as those pruned December first. The increase in yield of 

 fall pruned plants was nearly 46 per cent, the average yield per 

 plant being 1.2 pounds and .82 pounds of lint per tree for fall 

 and spring prunings during the second year's growth of the 

 plants.
