Mr. Clark: Yes. and tlu' Clark-W'illianisoii, too. W'c do 

 not remove them from the tray they arc on; they are left until 

 after the sac is gone, until distribution. 



The IVesident: I would like lo in(|uirc of .Mr. Wood if he 

 sees anv advantag'e in this over the oblons;' mesh.-' 



Mr. Wood: 1 have not used the oblong-. This seems to 

 answer the jiurpose very well indeed. 



The President: ^'ou stack those trays one u])on another? 



Mr. Wood: ( )h. no. 1 hud 1 can hatch as many trout eggs 

 on that tray as it will do to kce]) on a hatching tray. 



Mr. Clark: We hatch 40.000 fry and it doesn't take as much 

 space as you have there. In one box we hold the whole 40,000 

 fry until they arc ready to distribute. 



Mr. ^\'ood: At what age arc they distributed? 



Mr. Clark: When the sac is gone. If we did not hold them 

 in some such compact way as that. I don't know how we could 

 handle from 5 to 10 and 15 million trout eggs in an ordinary 

 hatchery. 



^Ir. Wood: I would like to say in all the Eastern hatcher- 

 ies the plan has been to use the single tray system. I have never 

 seen any other, and we, in our hatchery, seldom sell any fry before 

 they have been feeding at least six weeks. We hatch out 100,000 

 fr\' in a space 20 feet long and one foot wide, and they run 

 pretty thick. We always feed our fish before putting them out; 

 in fact, people won't buy them unless we do so. 



The President: Your fish hatch in mid-winter? 



Mr. Wood : I^sually alxjut the first of January. 



The President: Is there any further discussion about the 

 tray? 



Mr. Ravenel: P; is the same kind that Mr. lUick made; 

 practicallv the same tray. 1 had a sample sent to my office, but 

 it was all iron. 



Mr. Wood: How long ago? 



Mr. Ravenel: About a year ago. 



Mr. Wood : We have used this kind of trav five vears.
