18G7-1874. 65 



ern counties of Missouri were overrun much as in 1874. *<They came, 

 however, about a month later than in 1874. They were often so thick 

 that trains were seriously delayed on account of the immense numbers 

 crushed on the track." (Walsh's Illinois Eeport.) Innumerable eggs 

 were deposited in the autumn. 



18G7. — Serious damage was done by the young locusts in the spring, 

 particularly about Saint Joseph and Oregon. By the middle of July 

 they had nearly all left the State. A fresh, though less extensive inva- 

 sion, swept over Nebraska and portions of Kansas and the western 

 borders of Iowa and Minnesota, or, in Walsh's words, *' the main body 

 descended through Nebraska upon Iowa, instead of through Kansas 

 upon Alissouri," but the extreme northwest corner of Missouri was over- 

 run by the swarms, which were said to have come from the Eocky 

 Mountains. 



1868- — Considerable injury was done by locusts this year in the fol- 

 lowing counties: Andrew, Cedar, Clinton, Daviess, Gentry, Jackson, 

 Kodaway. There was, however, no fresh invasion from the west. 



1869. — Early in the season of this year locusts troubled the western 

 borders of Missouri. "They hatched out in countless numbers from 

 the 20th to 24th of March in Holt County. In Andrew County the 

 young, where the ground was smooth and hard, as 'sod' or prairie that 

 was plowed in the previous June, and not afterward plowed, de- 

 stroyed most of the wheat. * * * Our own stock was bad enough, 

 but on the 18th of June we received a large addition of flying ones from 

 the south, which in some places took half of the corn, although they 

 left on the 23d of June, staying less than five days. They came with a 

 strong south wind, and while here the north wind blew, and if they were 

 disturbed they would work a little south 5 but on the 23d, at 11 a. m., 

 the south wind blew and they rose simultaneously and most of them 

 left us; but our original stock not being able to fly remained. There 

 are no records of the presence of locusts in Missouri in 1870, 1871, 1872, 

 or 1873. 



1874. — The locust visitation of this year was the most calamitous to 

 Missouri, as to the neighboring States, of any yet recorded. A map of 

 the area overrun this year, as compared with 1866, is given in Mr. 

 Eiley's seventh, report. He states that the general direction from which 

 they came was from the northwest. They reached Holt County on 

 the 8th of August, and all the counties on the same line, north and 

 south, from Worth to McDonald, were reached during the latter part 

 of the same month. They then continued to make short flights, and 

 finally reached their extreme eastern limit toward the last of Septem- 

 ber. They flew no farther east than in 1866, except in the northern 

 part of the State, and only visited the western fourth or fifth of the 

 State. The swarms appeared during early August, and in most of the 

 counties invaded, the locusts stayed till frost, i. e., from their first ap- 

 pearance till frost swarms came and left, so that there were most always
