CVin REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



perature observations at right angles to the shore line, together with 

 corresponding meteorological observations for comparison with them. 

 It is expected that Prof. Libbey will soon be ready to announce the 

 results of the work so far completed. 



The Light-House Board and the Southern Pacific Railroad Company 

 have continued to cooperate with the Fish Commission in securing con- 

 tinuous series of water-temperature observations at many places along 

 the Atlantic seacoast and on some of the Western rivers. This service 

 is rendered gratuitously, and in the case of the light-house keepers at 

 least at their own personal volition, not being regarded as a part of 

 their regular or official duties. The records now on hand cover a period 

 of many years, and are of great value in connection with the study of 

 the migratory habits of our food-ftshes. Mr. H. E.. Center is now 

 engaged in making reductions of the daily observations to averages of 

 ten-day periods for publication in tabular form. The places at which 

 observations were made during the past year are as follows:
