the tree. An additional advantage that it should possess, is cheapness. 

 Now, "insect lime" possess some of those advantages, and may perhaps 

 be modified, so that it may possess all of them. It lias been proved by 

 use in Germany to be absolutely harmless to plants, and I am informed 

 tli at the trunk of a moderately large growing tree may be entirely coated 

 witli this substance without in any way endangering the tree itself. The 

 outer bark in large trees possesses no functions necessary for the con- 

 tinued growtli or development of the tree, and covering witli any viscid 

 substance which is not poisonous would not injuriously influence its growtli. 

 The line of insects against which such an application could be used is 

 large; for instance, all peach trees could be protected against the attacks 

 of the borer. It would not only prevent the moth from laying its eggs, 

 but if she alighted on the trunk covered by this "lime" the chances are 

 that she would be caught and remain sticking to it. Apple trees could 

 be protected against the Saperda in much the same way. Pear trees 

 could be protected against the attacks of Scolytus, and of course other 

 trees as well where they are subject to the attacks of these insects. A 

 coating put on early in the Spring before the leaves start would absolutely 

 prevent the emergence of any insects in the bark on the trunk, would 

 prevent the hatching of any eggs, and would prevent all insects lying 

 dormant in the crevices from making their way out. This would be an 

 especially useful thing in the case of the Pear Psylla for instance, that 

 hibernates in the crevices of the bark on the trunks of pear trees, and if 

 the application was made early enough to inclose the insects and prevent 

 them from coming out injury for the balance of the season need not be 

 feared. In fact, the number of uses to which a substance of this kind 

 could be put is very great, and the suggestion is made here in order to 

 induce entomologists, as well as farmers and horticulturists, to test this 

 substance during the ensuing season. The American agents for the "in- 

 sect lime" are Wm. Menzel.& Son, 64 Broad St., New York City, N. V.
