FisHEes Known To Ear Satt-MarsH Mosquitos 
No writer on the subject of the relation of fishes to the mos- 
quito problem can pass lightly over the magnificent work done by 
Mr. William P. Seal (10) of Delair, New Jersey, who for years has 
been known as an authority on the subject. Independently and later 
as fish expert to Dr. J. B. Smith, Mr. Seal showed the importance 
of utilizing the fish as one of the most important groups preying on 
the mosquitoes. In Dr. Smith’s report (13) and in later papers 
Mr. Seal (10, 11) has pointed out clearly that on the salt marshes,
