«6.— MANAGEMENT OF SPAWNING CARP. 



By I1ERK VOT¥ BEHR. 



[From a letter to Prof. S. F. Baird.] 



I have just been reading the letter of Edward Stabler in the 1883 

 Bulletin, page 127. Please tell it as loud as you can that cor p must be 

 Tcept hi/ themselves if you want them to spawn. Mr. Stabler tells that he 

 intends to clear out turtles, eels, snakes, &c, and well he may ! Bat 

 turtles will march over the ground again, and again fall into his lake ; 

 not to speak of the little eels that surprised him before and which may 

 peep in again. Let, if you like, the spawning-bed of the carp be not 

 more than a few meters square, but let it be free from all depredators. 

 Also put into the water branches of trees, evergreens, or willows, which- 

 ever you like. The carp will go among these, and there will be an op- 

 portunity to attach the eggs to the branches. With a system of such 

 little tanks you may just as well furnish your streams 500,000,000 of 

 carp as furnish your sea-shore with 500,000,000 of cod, and I dare say 

 the gain will not be less. You remember that, from time to time, very 

 large and delicate carp are caught in our large rivers. We are nearly 

 sure they were not hatched there, but escaped in one way or another 

 from breeding-ponds.

67.— WHAT FROGS SOMETIMES EAT. 



By B. II. DOWNMAN. 



[From a letter to Charles W. Smiley.] 



Mr. C. M. White informed me this morning that one of the bull-frogs 

 shot by him at his pond had in his capacious maw a good-sized frog 

 which he had swallowed sine grano saHs, and he thinks that frogs de- 

 stroy many young lish. If they feed upon each other, as I know they 

 do, I see no reason why they should not feed upon fish.

 NOCK RBVER l.V DAMS. 



By B. II. DOWNMAN. 



[From a letter to Charles W. S'uiley.] 



Fifty years ago, before the Rappahannock River was obstructed by 

 the erection of mill-dams, shad were taken in large quantities at Bev- 

 erly's Ford, and white perch and herring as high up as the Fauquier 

 Springs.
