The water has fallen in this field about 6 inches since May 12, 

 and the gage is still on the decline. At this rate it may not be man}' 

 days till the water in the field will be so low that the fry will be 

 scalded or left high and dry. 



Water in Danhole's field 8 to 18 inches deep, and going down at 

 rate of i inch a day. 



Carp fry ^ to ^ inch long are abundant, and easily taken with 

 cheese-cloth seine. 



June J. Carp coming into market include a good many females 

 full of eggs, some dressing only half their round weight; but most 

 have evidently spawned. 



[June ^-22. This interval was taken up by the Rock Island plank- 

 ton trip and preparations for the opening of the University Summer 

 School.] 



June 2^. Water has fallen about 1.8 ft. since the first of June. 

 Depth of water 4 to 6 inches in south end of Danhole's field. Tem- 

 perature of water 85° Fahr. Rushes (Scirpus)^ as high as a man's 

 shoulders, choking up the marsh almost completely except for scat- 

 tering small open spaces 10 to 30 feet across. In these openings we 

 found small fry, ^ inch to i inch long, of bass, bluegill, and crappie, 

 but no carp. Have all the carp gone out of the field? If so, where 

 are they? We searched for them in the deeper water of Lynch 

 Slough, just outside of the field, but could find no trace of them. 



June 2^-^o. Tried repeatedly to get carp fry in waters adjacent 

 to Danhole's field, — Lynch Slough, Crabtree dredge ditch, Thomp- 

 son's Lake, west shore, between dredge ditch and club house, etc. 

 No trace of them found. 



July I. Visited Beck's ponds. They are now very low and all 

 shut off from connection with the township ditch and the river, some 

 being dried up completely. If dry weather continues a few weeks, all 

 will be dry. In one of the largest ponds, 3oXicmd ft., just dried up, 

 several hundred dead carp, i to 2 inches long, were found. 



In small pitlike depressions (cow tracks?) in the bottom of this 

 pond, holding from a quart to a gallon of water, with a temperature 

 of 92° Fahr., we found half a dozen carp, ^)4 inch long, well-fed and 

 lively, although all about them were skeletons and decaying bodies of 

 hundreds of others. 



July 5. Visited Danhole's field. Most of the field has gone dry 

 except for small areas in the middle of the densest flag patches, 

 where water from 2 to 6 inches is present, and the two lotus ponds, 

 which have 2 to 3 feet of water. We searched high and low for 

 young carp, but found none, alive or dead. In the lotus ponds, found
