EEOOED OF AUTUMN FLIGHTS EAST OF THE EOOKY 

 MOUNTAINS IN 1877. 



[The following replies are to a circular sent out by Mr. Hiley, inquiring especially as to tbe move- 

 ments of winged locusts in the autumn of 1877, after the northward flight had ceased, the inquiry be- 

 ing as to whether such autumn swarms were noticed. These replies show that tliere was a consider- 

 able movement of scattering swarms; that the direction was essentially south, and that no serious dam- 

 age was done. Eggs were laid in but a few exceptional instances, and no young locusts will hatch in 

 the spring of 1878, except in a few small and restricted areas widely separated. The names of the 

 correspondents may be learned by referring to the list in Appendix 26. J 



MINNESOTA. 



Jamesville, Waseco County. — " Some few settled here about the time of the departure 

 of those first hatched, but all left again i mmediately. None since." 



Zuverne, EocJc County. — " Swarms passed over from north-northwest and northeast 

 on following dates : June 27; July 5, 8, 9, 10, 15, 20, 28, 31 ; August 1, 2, 7, 8, 9, 11, 12, 

 13 ; some alighting in small squads, but doing no damage." 



IOWA.

 north-northeast and northwest passed over: July 15, 16, 20, 27, 28, and 31; August 1, 

 6, 7, 8, 9, 21, and 22. During the flights more or less of them alighted." 



Algona, Kossuth County. — " The wind was from the north when the Minnesota crop 

 passed over." 



Ames, Story County. — "A few swarms, or straggling parts of swarms, were noticed 

 high in the air, going south. No dense swarms were seen." 



Carroll, Carroll County.^—" Several swarms from the northwest passed over us, and 

 small portions of them alighted. They lay all over in pairs, but took wing with the 

 first favorable wind, leaving no eggs." 



Chickasaiv, Chickasaw County. — "No." 



Council Bluffs, Pottawattamie County. — "Fresh swarms passed over frora the north. 

 Some settled for a nightly visit ; in some cases remained a day or two waiting for a

 August, but did little damage."

 came down and settled for a time. They came from the northwest, and a portion of 

 them remained about two weeks, doing a little damage to gardens and small grain."

Malvern, Mills County. — "A few swarms, not large, passed over here from the north-

 ward ; but whether from north, northeast, or northwest, I cannot say." 



Webster City, Keokuk County. — "Myriads of grasshoppers passed over, apparently 

 going southward, as soon as they had acquired the power of flight. A few alighted,
