escape, it may be possible that a thousand insects were at work on the 

 dead pine the morning we were there. 



In conjunction with these facts the further fact must be taken into 

 consideration that for two weeks we had been beating branches, Hving 

 and dead, of the same species of tree at various places in Florida 

 with the usual mixture of success and failure, sometimes no result, 

 sometimes three or four specimens, never any large number, to 

 appreciate this illustration of the value to the beetle collector of a 

 recently felled tree. The practice of cutting down trees of various 

 species, of partly cutting through branches so that they will hang 

 with their withered leaves conveniently for beating, is not new; but 

 it may be worth while to add a list of the insects we caught in two 

 hours on one tree to emphasize the advantage of this method of 

 collecting.
