the capital, of garden vegetables, grass, and clover, and left the ground 

 as if burned with fire. Corn is eaten to the roots. About Lawrence, 

 though very numerous, yet coming so late they did not do essential 

 damage, but deposited their eggs. In Douglas County they made their 

 appearance by the billion. The prevailing winds in the State during 

 August and September were westerly, and the season was dry and hot. — 

 {Practical Entomologist^ ii, 3-4.) 



1867. — The locusts this year, according to B. D. Walsh, '' took a rather 

 more northerly course, the main body descending through IsTebraska 

 upon Iowa, instead of through Kansas upon Missouri. Still in both years 

 there were flying columns of the enemy, that deviated a little from the 

 general line of march either to the right or to the left. For, as will be 

 seen hereafter, some of the more northerly parts of Kansas and the ex- 

 treme northwest corner of Missouri were invaded by the army of 1867 j 

 and as I have shown in the Practical Entomologist, the southern i)arts 

 of Nebraska were very generally invaded by the army of 1866." Nearly 

 as last year, the invasions occurred from August 25 to September 30, 

 and the locusts came from the northwest. — (Walsh's First Illinois Rep.) 



1868. — Locusts, which hatched in the spring, devastated the State, 

 locally, and the region west of Fort Riley was ravaged in the autumn, 

 but whether by foreign swarms or those native to the State is not stated. 

 August 7, locusts appeared in Riley County, flying from the northwest 

 apparently, as a southeast wind prevented their leaving on the 8th. It 

 is possible that the swarms came from Iowa and Minnesota, rather than 

 from the west. In the early part of August they attracted attention 

 in Kansas and during the preceding month in Iowa and Minnesota. 

 (American Entomologist, i, 74.) From this fact we infer that the inva- 

 sions were local and from the north. 



1869. — For two years, apparently, the progeny of those which over- 

 run the State in 1866-'67 remained and did some damage. In 1869 the 

 young hatched out In Saline, Lyon, and Brown Counties, but left as soon 

 as they acquired wings, namely, about the middle of June. They were 

 destructive east of Nemaha County, but no extended damage was done 

 iu the State generally, and none were seen in 1870 and 1871. 



1872. — This year " foreign '' locusts did some harm in parts of Kansas. 

 At Beloit they appeared in the last week in August and devoured every- 

 thing green. — (Riley's Seventh Report.) 



1873. — While Nebraska and the country to the north was generally 

 overrun in 1873, there is no record of their appearance in Kansas. 



1874. — This was the worst locust year in Kansas, the State, like its 

 neighbors north and south, suffering extremely. Mr. Riley in his seventh 

 report says the locusts swept over the State '4n overwhelming hordes 

 from the plains of Colorado on the west, and the fields of Nebraska on 

 the north, in many instances clearing off all traces of vegetation iu a 

 few hours." The corn crop was ruined by them. They appeared in 

 every county, so far as the records show, except Clarke, Comanche,
