No. 7.] DAWSON — LOCUST INVASION OF 1876. 415 



the South Saskatchewan Valley, where they are said to have eaten 

 up all the grass, driving the buffalo eastward to the vicinity of the 

 Touchwood Hills, Souris Valley, etc. 



Fort Calgarry, Bow River, N. W. T. (John Bunn.) Did not 

 appear here during the summer of 1876, but were reported as 

 abundant on the plains to the eastward. 



Fort Walsh, N. W. T. (J. M. Walsh.) Produced from the 

 egg, hatching about the middle of May, and remaining till 

 the middle of August, when they flew north-westward. Other 

 swarms arrived on the wing from Montana, about the middle of 

 July, and for some time thereafter. These also passed on to the 

 north-west. All crops destroyed. No eggs left. 



Fort Pitt, AT. W. T. (W. McKay.) There were no grass- 

 hoppers within a distance of 300 miles west of this. 



Prince Albert, N. W. T. (Bishop of Saskatchewan.) No visi- 

 tation of grasshoppers. 



Battleford, N. W. T. (T. Little.) Did not appear in 1876, and 

 are never known to have reached this region. 



Carleton House, N. W. T. (L. Clarke.) Grasshoppers were 

 seen in huge swarms about 150 miles south of this, flying still 

 southward. Did not appear here. 



Swan River Barracks and Livingston, N.W.T. (F. Norman, 

 J. H. Kittson, M.D. and B. Miller, M.D.) Produced from the 

 egg, from about the 25th of May till June 1st, remaining till the 

 7th of August, when they departed north-eastward. (One re- 

 port says they died in the country.) A few arrived from the 

 south-west about the second of June, and alighted. Foreign 

 swarms on the wing were observed passing overhead from the 

 20th to the 27th of July ; but, owing to strong wind, they did 

 not alight. These also went north-eastward, or eastward. About 

 the 8th of August, great swarms appeared from the south-west, 

 many alighting. These departed about the 10th of August, flying 

 southward. All crops destroyed. No eggs deposited. For twelve 

 years before July 1875, no grasshoppers were seen here. In 

 1876 the green crops were entirely destroyed before the middle 

 of June, when the insect was no larger than the ordinary house- 

 fly. Myriads are said by the Indians to have perished in lakes 

 Winnipegosis and Winnipeg.
