312 BULLETIN OF THE UNITED STATES FISH COMMISSION. 



for a business enterprise. A common and widely distributed West In- 

 dian tellin ( Tellina radiata), a very handsome shell-fish, is eaten regu- 

 larly (that is to say, it is a staple article of food) at Manatee, Fla., and is 

 called by the people there the. "sun clam;" and, as before stated, there 

 are several species of cockles of edible value, some of large size, the 

 quality of which I know nothing about. Sometimes these are eaten by 

 the people who live along the Florida coast.

Whitefish. — The whitefish eggs (1,000,000) sent from Northville 

 arrived February 11, 1885, in splendid condition, and were all hatched 

 by the 15th of April. I lost none except such as were unavoidably in- 

 jured — not more than 50. They were put into Spirit Lake. This lake 

 is about 4 miles square with a depth of about 22 feet, somewhat deeper 

 in places. The shores are sand and gravel, with occasionally bowlders. 

 The bottom is soft, out in the lake, say, from 20 to 40 rods ; it seems to 

 be a deposit of silt or fine mud, and seems to be full of animal life. 

 If it is cold enough, I think they will do well. They were very lively 

 and strong. We ought to hear from them, and no doubt would if we 

 could catch them. 



Loch Leven Trout. — The Loch Leven trout from the hatchery at 

 Anamosa, in this State (about 30,000) were brought here by Mr. Aldrich, 

 April 3, in good condition, and were put iuto West Okoboji Lake, be- 

 ing the only suitable lake in the State. This lake is in Dickinson County 

 and is of the chain of lakes of which Spirit Lake is one. The water in 

 Okoboji is very clear, never turbid, and very deep in some places — 170 

 feet ; has deep bays with gravelly shores mainly, and is about 6 miles 

 long and from one-half to 2 miles wide. They were put in at the head. 



Wall-eyed Pike. — As to the wall-eyed pike, I have some eggs to 

 send, but they are very glutinous. I have no trouble in impregnating 

 them and have hurdles on which 1 put the eggs. I am anxious to send 

 some eggs, but after repeated manipulations they will still adhere in 

 bunches. Glass jars will not do. I have found that out, but by scat- 

 tering them (after impregnating) on willow hurdles, I think they will 

 be all right. In some of the eggs the. embryo was very distinct, two- 

 thirds developed forty-eight hours after impregnating. The pike are 

 the common white-bellied ones, weighing front 2£ to 6 or 8 pounds, and 

 are among the best fish, if not the best (excepting, of course, whitefish 

 and trout), there are in this country. I have some pickerel {Esox lucius) 

 eggs in good shape and doing well. They are not glutinous.
