Mr. V. C. Gambell, a student in entomology whose home 
was at Winfield, in Henry county, saw no locusts there but a 
man in that vicinity reported hearing them and had seen one 
shell. This is rather uncertain testimony especially in view of 
absence of reports from this and the adjoining county to the 
north. If correct it shows a very feeble representation of the 
insect there. Mr. Gambell noticed in traveling on the Chicago, 
Rock Island & Pacific railroad from Brooklyn to Iowa City 
that the trees were injured, apparently by Cicada. If all due 
to Cicada this would carry the brood into Poweshiek county 
several miles further west than indicated by other reports. 
Mr. E. N. Eaton of Keota, in the extreme east of Keokuk 
found no locusts and no reports of them for that county. 
Mr. P. H. Rolfs reports for the central eastern border of 
Tama county that there were no locusts and none for about 
five miles to the east of the county line, while Mr. F. A. Sir- 
rine reports for a point about six miles further north that 
locusts were in Tama county, two miles west of the county line 
in Geneseo and Clark townships, but not in townships west so 
far as he could learn. 
The following additional statements from correspondents 
have a special significance in determining the border line; 
Louisa county, Wapello township, “None; a few in north 
part of the county. ” Columbus City, “Locusts present.” In 
Keokuk county. Clear Creek township, “None here this year, 
but here seventeen years ago.” Prairie township, “None yet; 
were here seventeen years ago.” Garman township, “No 
locusts, last in 1877” [1878 Brood XIII probably]. Iowa county, 
York township, “Locusts in limited numbers in northeast third 
of this township.” Poweshiek county, Malcom township, 
“None.” Sheridan township, “None.” Bear Creek township, 
“None. None seventeen years ago.” Warren, “None yet, 
July 15th. Were here sixteen and seventeen years ago; second 
year in great nunbers and did great damage to fruit trees and 
shrubbery.” Chester township, “No seventeen year locusts to 
amount to anything; appeared in 1861 and 1878.” [Brood XIII]. 
Black Hawk county, Spring Creek township, “Yes, and seven- 
teen years ago.” East Waterloo township, one correspondent 
says: “ No, never here.” Another says: “No. A few seven- 
teen years ago.” Payette county, Westfield township, “None;
