416 THE CANADIAN NATURALIST. [Vol. viii. 



Swan Lake Rouse, N. W. T. (D. McDonald) Not seen here 

 in 1876; and during Mr. McDonald's experience of four years 

 very few have visited this part of the country. 



Little Saskatchewan, N. W. T. (K. McKenzie.) Second week 

 of July a large flight observed going south one point west. 

 Hatched in this country, and north-west of Lake Manitoba. 



Manitoba House, iV. W. T. (J. Cowie.) Produced from the 

 egg about the first of June, leaving about the first of August, 

 going south-eastward, or south-westward, according to the direc- 

 tion of the wind. On the first of August, foreign swarms were 

 also observed, and these continued passing and occasionally 

 alighting for about a week, going south-westward. Crops slightly 

 injured. No eggs deposited. 



Woodside, Man., (T. Collins.) None hatched here; but foreign 

 swarms, more or less extensive, continued to pass over for 

 six or eight weeks, coming from the north and north-west, and 

 going southward. Some alighted ; but it is stated that though 

 in quantity, and remaining long enough to have destroyed the 

 greater part of the crop, " strange to say, they did nearly no 

 damage. They did not seem to have the same energy, nor did 

 they eat voraciously as in former years." 



Gladstone, Palestine P. O., Man., (C. P. Brown.) None 

 hatched. Swarms observed to arrive on the wing on the 27th of 

 July. These alighted and remained about nine days. Seen pass- 

 ing over for several days before, but did not alight. " They 

 probably would not have alighted on this day, but for some 

 misty showers or shadows of large clouds. They appeared to fall 

 only in patches, probably the spaces covered by the shadows." 

 Also continued to pass over for about two weeks after this date, 

 but few came down. The insects came from north-west by north, 

 and most of them probably went south-easterly. Loss of crops 

 perhaps 5 or 6 per cent. No eggs deposited. 



Oak Point, Lake Manitoba, Man., (J. Clarke.) Observed 

 about the middle of July for two weeks, passing overhead at in- 

 tervals, when the weather was clear and warm. Supposed to 

 come from the western plains. General direction of flight, south- 

 eastward. No eggs deposited. Many grasshoppers observed t» 

 fall into the lake, and in several places were afterwards washed 

 up in windrows a foot thick along its margin.
