died from the effects of " the long-continued cold rains occurring shortly 

 after the eggs began to hatch." "No young locusts were seen after the 

 14th of Mdj. None of the locusts arrived at maturity, neither were any 

 seen off their hatching-grounds." (United States Signal Of&ce.) 



THE LOCUST Uf ARKANSAS. 



The first recorded instance of locusts extending into this State was, 

 according to Mr. Eiley, in 1876. They overran the extreme north- 

 west corner of the State, and were particularly injurious in Ben- 

 ton County, the damage being mostly confined to this county and the 

 region south of it, the insects not extending east to Carroll County. 

 *'They made their advent from the 7th to the 15th of October, coming 

 with the wind from the northwest and flying south and southwest, 

 until they struck the base of Boston Mountain. As in our own [Mis- 

 souri] southeast counties, wheat was greatly injured by them, and eggs 

 were laid up to the time winter set in." (Eiley's ninth report.) 



In 1877, Arkansas was again visited, but to what extent is unknown. 

 The only data at hand are the following statements from correspondents : 

 At Bentonville, Benton County, -'A few passed over the last days of Sep- 

 tember, and a very few alighted in some localities." Again it is stated 

 that "fr-esh swarms passed over from the northwest, but none settled." 

 At CarroUton, Carroll County, no swarms were noticed during the pres- 

 ent year, though they passed over in the autumn of 1876. 



.THE LOCUST IN MISSOURL 



The history of the invasion of this State by the Eocky Mountain 

 locust has been so fully set forth by Mr. B. D. Walsh, in his Illinois 

 report, and by Mr. Eiley, in his seventh, eighth, and ninth annual re- 

 ports on the injurious insects of Missouri, that the following account 

 is simply a brief abstract of their statements, the portions quoted being 

 in most cases taken from Mr. Eiley 's report. 



1820 or 1821. — In one of these years, it is uncertain which, Western 

 Missouri was visited by locusts. " They came in the autumn by millions, 

 devouring every green thing, but too late to do much harm. They 

 literally filled the earth with their eggs, and then died. The next 

 spring they hatched out, but did but little Jiarm, and when full-fledged 

 left for pnrts unknown. Other districts of country have been visited 

 by them, but, so far as I could learn, they have done but little harm 

 after the first year. (Prairie Farmer, June 15, 1867.) This statement 

 is corroborated by the following: '^A Missouri paper publishes a state- 

 ment by an old settler, that great numbers of grasshoppers appeared in 

 September, 1820, doing much damage. The next spring they hatched 

 out, destroying the cotton, flax, hemp, wheat, and tobacco crops j but 

 the corn escaped uninjured. About the middle of June they all disap- 

 peared, flying off in a southeast direction. ( Western Bural, 1867.) 



18G6. — The next recorded invasion took place in 1866, when the west-
