The Light House Board and the Southern Pacific Railroad Company 

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

 tinuous series of water-temperature observations at many places along 

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

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

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

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

 the migratory habits of our food-ftslies. Mr. H. R. 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 tlie past year are as follows:
