EXHIBITION OF "ORIGINAL CONTRIVANCES" FOR USE AT BROOK 

 TROUT HATCHERIES; WITH DESCRIPTION AND DISCUSSION. 



By C. C. WOOD. Plymouth. Mass. 



Gentlemen: 1 have not prepared any paper at all on this 

 stibject; I just wish to show you some "Orio^inal Contrivances." 

 If anyone has anything- l)etter I should be very glad to know it 

 now.

Fig. 1 



This is a hatchiui^' tray (his,', i). that we use over in Ply- 

 mouth, made entirely of wire. It is raised up from the bottom of 

 the hatching trough by a little wire leg at each corner, so. When 

 it is placed in the trough there is a circulation of water under- 

 neath, as well as over, and being all wire it gives more room for 

 the eggs, and then there is no wooden edge to collect slime or 

 fungus. 



Mr. Clark: As he goes along are we going to ask ques- 

 tions? If so, I would like to ask a question on the tray now. 

 Do we imderstand that you use that tray for hatching the eggs? 



yiv. Wood: Yes, sir. 



]Mr. Clark: I w^ould like also to ask Mr. Wood how many 

 trout he handles? 



!Mr. Wood : About 700,000. We put on that tray, say 

 10,000 eggs, and the eggs are left there until hatched. 



]\Ir. Davis: Do you think it would improve it to have an 

 oblong mesh? 



Mr. Wcnxl: Xot at all.
