Lawrence county has been invaded from other parts, but should 
rather attribute the recent injury to undue increase of a species | 
always there, albeit not generally noticed and heretofore unre- p 
corded. This increase may in fact be due to the excessively dry 
weather that characterized 1880 and 1881 and previous years, 
reacting wet weather not having yet produced an injurious effect 
upon it. In this view of the matter, which seems to be most | 
reasonable, the outlook is rather encouraging than alarming, and | 
we fully expect to see this view corroborated by subsequent i 
events, 7. e., the pest will sink back to its state of harmlessness 
next year and probably perish in immense numbers during WF p 
coming winter. We would not, however, by any means have the 
farmers relent from the measures recommended by Mr. Lintner 
in the circular already alluded to, though he can scarcely expec 
them to carry out his advice without some obligatory law ot 
some compensation from the State—C. V. R., in Scientific Am
