an abundance of large-mouth black bass (i inch to 2J/4 inches), young 

 black bullheads, and various minnows (Cyprinidcc). In the flags in 

 the south end of the field, found sunfish and crappie fry in water 2 to 

 4 inches deep. They are shut off now from any connection with Lynch 

 Slough or Thompson's Lake, making it practically certain that they 

 will perish with further drying. 



In the soft mud of the nearly dried-up bottom of the two "guts" 

 in the south end of the field, draining the field southward into Lynch 

 Slough, we found numerous dead crayfish and snails, but no carp. It 

 is through these two "guts" that the fry seem most likely to have 

 gone out of the field — if they went out at all — as the water receded 

 between June 5 and 20. 



July 7. Took 200 specimens of young carp, i to 2 inches long, at 

 the head of Liverpool Lake, west shore, with one haul of the 120-ft. 

 minnow seine. They were taken in water i to 3 feet deep, moderately 

 clear of vegetation, but with a thick fringe of Ceratophyllum and Spi- 

 rogyra along shore. The bottom is mixed hard clay and black mud, 

 with some vegetation as far as 100 feet out from shore; the water is 

 slightly turbid, from the strong current flowing in from the river 

 through the inlet ditch opposite Liverpool. 



Among the specimens taken were a good many of the mirror and 

 leather varieties. The large number saved in the haul with 34 inch 

 mesh, through which many probably escaped, suggests the probability 

 that there were in all several thousand in the shallow water at the 

 northwest end of the lake, below the inlet ditch. 



July 12. Took four specimens of young carp ( i to 2 in. long) 

 in one haul of a 15-ft. seine, on the gravel point below Sam Bishop's, 

 on the west shore of Quiver Lake, in Ceratophyllum. 



July 24-^1. Took a few young carp, i to 2 in. long, on the west 

 shore of Illinois River, opposite Quiver Beach, along the edge of the 

 muddy bank, in Ceratophyllum. 



August 5. Allen tried the haul at head of Liverpool Lake, where 

 200 carp were taken July 7. No young carp obtained. Water has 

 fallen 2 feet, and the vegetation zone is nearly all out of water. 



August p. Tried the west shore of Illinois River, opposite Quiver 

 Beach, where we took a few young carp July 24-31, but got none. 

 Water has gone down one foot, and left most of the Ceratophyllum 

 high and dry. 



August 10. Tried the head of Liverpool Lake again. No trace of 

 young carp. The water has receded, leaving the vegetation zone dry. 



August II. Tried half a dozen hauls with 120-ft. seine in Clear 

 and Mud lakes and Courtwright Slough, but got no carp, young or old.
