CHRONOLOGY: MONTANA, 1864-1871. * S3 



in Prickley Pear Caiion, iu 1863, flyiug from the east ; they were very 

 destructive to the foliage of trees, &c. 



18G4. — The locust, years at Canton, Meagher County, were 18G4, 1865, 

 1866, 1867, 1868, 1869, 1870, 1871, 1872, 1873, 1874, 1875. In 1876 no 

 winged locust, plenty of young ; and 1877. (W. J. Tierny.) Locusts, 

 then, have appeared at this point for fourteen consecutive years. 



1865. — Dr. Lamme, of Bozeman, told me that in 1865 the locusts came 

 to Bozeman late in the season from tbe northeast, and laid eggs which 

 hatched in 1866. Mr. B. Kline also states that the locusts occurred at 

 Bozeman in 1865 and 1866. At Beartown, thirty miles west of Deer 

 Lodge, locusts came in 1865 in a thick swarm from the northeast. Mr. 

 J. J. Healy, who lives in the Sun Eiver settlement, informed us that 

 locusts came into that valley in July and August, 1865, and laid eggs 

 which hatched out in 1866. 



1866. — Mr. George McCullum states that in the Upper Missouri Yalley, 

 near Crow Creek, locusts appeared in 1866, 1867, 1868, 1869 (this was 

 the worst year), 1870, 1871, and 1872. Kone were seen in 1873 j but they 

 appeared again in 1874 and 1875 (this was one of the worst locust 

 years), and in 1876 half of the crop was lost. Locusts were abundant 

 and destructive at Bozeman in 1866. (P. W. Macadow.) In the spring 

 they eat up the wheat in the Prickley Pear Yalley, south of Helena. 



Mr. Chauncey Barbour, editor of the Missoulian, stated to me that in 

 1866 locusts came into Bitter Eoot Yalley, at Missoula, from the north 

 and northeast and south, from British America, down the Flathead 

 Eiver and over the Main Divide in August, and the eggs laid by them 

 hatched in 1867, and the young were very destructive. None were after- 

 ward seen from 1868 to 1874 in Missoula, or to the north or west, until 

 1875. At Fort Benton they abounded in 1866 and 1867 ; there were 

 but few in 1868 and 1869. At Hamilton, Gallatin County, no eggs were 

 deposited in 1866, within one hundred miles east or west, north or south, 

 from that locality. (John Potter.) But young hatched out this year 

 in abundance. 



Mr. Granville Stuart, of Helena, informs us that he went to Montana 

 in 1857, but he saw no locusts till 1866, when they appeared in dense 

 swarms of unknown extent. They have hatched out in different locali- 

 ties ever since, but not in the same place. The locust years at Deer 

 Lodge were 1866, 1869, 1872, 1874, 1875, 1876. This information extends 

 up to the spring of 1877. 



1867-1868.— Locusts arrived in the Sun Eiver region in 1867 and 1868, 

 always coming from the northeast and east, and departing in a westerly 

 and southwesterly direction. (J. J. Healy.) 



1869.— Mr. E. M. Goin, of Sterling, observed locusts at this locality 

 in 1869, and also in 1873, 1874, 1875, 1876. 



1870. — We were told by a person in Bozeman that locusts were seen in 

 masses on the snow-banks on the Yellowstone Mountains. 



1871. — At Fort Benton locusts occurred in abundance in 1871, 1872,
