92 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



graph on this subject which he has liad in preparation for some time. 

 The rest of the investigators were occupied with special studies of their 

 own selection, some of which have a more or less direct bearing upon 

 fishery topics, and in course of time will undoubtedly be found useful 

 in arriving at practical deductions. 



Mr. Vinal N. Edwards, tlie permanent collector of the Fish Commis- 

 sion at Woods Hole, kept up during the entire year his customary daily 

 observations on the fishes of the region and on the temperature of the 

 water. During the summer he also assisted in obtaining material 

 required for the laboratory. 



The steamer Fish Raid; Lieut. Robert Piatt, U. S. N., commanding, 

 was at Woods Hole from August 12.5 to October 2, and during that 

 period was utilized mainly in running the lines of observing stations 

 in connection with the investigations of Dr. James I. Peck on the food 

 of fishes. During the week preceding her arrival at Woods Hole she 

 was placed by the Commissioner at the service of the biological section 

 of the American Association for the Advancement of Science, which 

 was then meeting at Brooklyn, N. Y., and made two dredging trips 

 from that point.
