An extensive treatment of proliferation in its relation to the boll weevil. From a large

 weevil mortality of 13.5 per cent in squares and 6.5 per cent in bolls. The author con- 

 cludes that the weevil larvae are killed mechanically by pressure from the prolifid cells 

 and not from any toxic property of those cells.
