desolatiDg the region of country he has traversed. He says: *The 

 only thing spoken of a1)out here is the grasshoppers. They are awful ; 

 they have actually eaten holes in my wagon-covers, and in the 'paullns 

 that cover my stores. A soldier on his way here lay down to sleep in 

 the middle of the day on the prairie. The troops had been marching all 

 night. His comrades noticed him covered with grasshoppers, and 

 woke hitn. His throat and wrist were bleeding from the bite of these 

 insects. This is no fiction.'" 



1866. — " In regard to the raids here, the one in 1866 did nob extend 

 but about fifteen miles east and fifteen miles south of here, while the 

 next raid went a little farther east and south 5 till the last one went 

 over a large part of the northwest portion of Iowa." (A. Strong.) 



1867. — Young, unfledged locusts made sad ravages upon the crops of 

 Southwestern Iowa. Later in the season there was a general invasion 

 of the State, the swarms arriving at Fort Dodge September 10, in Clark 

 County about October 5. " So far as we have been able to learn they 

 did not appear beyond the eastern boundaries of Polk and Marion 

 Counties in 1867." (Iowa Homestead.) ^' Grasshoppers came here from 

 the southwest on the 10th September, 1867, and deposited eggs shortly 

 afterward. The young hatched in the May and June following, taking 

 the garden vegetables as fast as they could find them ; oats and wheat 

 also suffered severely."^ ''A swarm of grasshoppers swept from Fort 

 Benton to Missouri, reaching as far east as the Des Moines Eiver. I 

 have read of them as being at Denver, Colo., at the western terminus 

 of the Kansas branch of the Pacific Eailroad,"^ Mr. Whitman writes us 

 that upon inquiry he finds " that the visit of 1867 was very extensive in 

 that State" (Iowa). He adds that Ida, Carroll, Greene, Sac, Webster, 

 Adams, Guthrie, Pocahontas, Orange, Woodbury, Pottawattamie, Page, 

 Hamilton, Calhoun, Adair, Audubon, and Plymouth Counties were vis- 

 ited this year. 



1868. — Locusts visited Page County August 7 and 8 in "fearful num- 

 bers"; they also visited Boone, Buena Yista, Woodbury. 



1870-'72. — *' In 1870 Algona was visited, and in 1871 the progeny 

 hatched by myriads till after the 1st of June, and left about the 1st of 

 July." (Riley's seventh report.) "In the seasons of 1871 and 1872 they 

 flew over, but few alighted 5 no damage was done." (H. J. ]S"ewell, 

 Athol, Sioux County.) 



1873. — The northwestern counties of Iowa were swept by swarms of 

 locusts. (Riley). Harrison County was visited and some destruction 

 done ; they deposited eggs, which hatched out April and May of the 

 next year. Athol, Sioux County, was visited by a heavy swarm from 

 the south in June, which did much damage; the insects deposited eggs. 

 (H. J. Newell.) 



1874.— Much of the injury done in Iowa this year resulted from the 



s Oscar J. Strong, Kolfe, Pocahontas County, Iowa, in Western Farmer, February, 1869.
