In this connection it is interesting to note that Chambers^ relates 

 a native method of protecting maize from weevils by mixing the grain 

 with finely powdered wood ashes. He notes that a layer of wood 

 ashes on the outside of the sack alone is effective. The editor^ of the 

 publication in which Chamber's article appears states that a layer of 

 building lime on the floor of the storing place and between successive 

 layers of bags gives satisfactory results. While one would normally 

 attribute these results to the caustic effect of the ashes or lime, the 

 fact that the substance appears to protect even when not in direct 

 contact when taken with the well known hygroscopic qualities of ashes 

 and lime leads one to suspect that here we have the practical applica- 

 tion of the effect of low relative humidity.

THE SEVENTEEN-YEAR LOCUST IN WESTERN NEW YORK 



By C. H. Hadley, Jr., and R. Matheson 



During the summer of the year 1916, the periodical cicada or "seven- 

 teen-year locust," Tihicen septendecim, appeared in varying numbers 

 in several counties in western New York. This brood, brood VII of 

 Marlatt's nomenclature (brood XIX of Riley's nomenclature), last 

 appeared in New York in the year 1899, and was reported by Lowe' 

 and Felt* as having occurred in Monroe, Livingston, Ontario, Yates, 

 Cayuga, Madison and Onondaga Counties. 



The following notes of the occurrence of these insects during the 

 past summer, incomplete as they are, are presented as a matter of 

 record. 



Livingston County — On June 22, the insects were found in large 

 numbers in Sonyea, on the grounds of the Craig Colony for Epileptics. 

 One colony was in a grove of young oak trees covering ten or more
