the river bottom in this vicinity daring the past month, but I am of the 

 opinion that they have been driven in here by prairie-fires that have 

 burned the country for many miles around this post. I observe them 

 copulating quite extensively up to the present date. We had quite a 

 severe frost on the night of the 2d and 3d instant, making ice half an 

 iuch thick, since which time some of them have disappeared. 1 think 

 they have sought shelter in the long grass and weeds. The^^ seemed 

 very ravenous, eating up everything green, and even the small potatoes 

 left on the ground ungathered. I have just this day, for the first time, 

 discovered some few of them depositing their eggs, but I do not think 

 any danger may be apprehended next summer from the small number 

 in this vicinity." 



Mr. Whitman reports that very few hatched in Armstrong County, 

 and some died ; in Bramble County, May 18, no locusts or eggs were 

 observed 5 at Scotland, Hutchinson County, eggs were reported within 

 eighteen miles. " 'New settlers from Yankton to Lake Kampeska, Deuel 

 County, did not see a single grasshopper ; there are none in this county. 

 At Grand Forks, " no grasshoppers in this section this year. A few 

 passed over at different times during the month of July, but none lit. 

 No eggs here.'^ In Southeastern Dakota the injury was sporadic and 

 slight, as reported by Mr. Codington. 



THE LOCUST IN MONTANA. 



1861. — Mr. P. W. Macadow tells us that he observed locusts in Silver 

 Valley, on the Prickly Pear Creek, in large swarms, about the middle 

 of July, 1861. He thinks they hatched out there. They also occurred 

 in this year at Bozeman. 



1862. — In August of this year, Mr. J. D. McCammon, tells us that 

 locusts deposited their eggs in the region between Forts Benton and 

 Shaw, and east of south a little beyond Fort Shaw, but they did not 

 hatch out in the spring of 1863. The winter was very mild, there was 

 no snow, and the roads were dusty. In January, 1863, there were very 

 heavy warm rains, and he thinks the eggs were destroyed by the un- 

 usually mild weather. 



In July, 1862, above the Vermillion Hills, they came from the north- 

 west in great numbers. (eXames H. Harkness.) 



In August, 1862, Mr. James Gomley tells us he observed locusts, in 

 myriads, between Sun Elver and Fort Benton, flying in a southerly 

 direction toward the Sun Eiver from Fort Benton. They ate up the 

 tall grass so that there w'as none left for the cattle. 



In 1862 large numbers of grasshoppers were observed on Grasshopper 

 Creek, near Bannock City. (James Stuart, contributions of the Hist. 

 Spc. of Montana.) 



1863. — Young locusts in great abundance were observed on the 

 Yellowstone Eiver, near where Bear Eiver empties into it, April 26, 

 1863. (Stuart, Hist. Soc. Montana.) Mr. J. J. Healy states that he saw
