Tiventy-ninth Annual Meeting 



Mr. Thompson: I would like to ask if he gets his total 

 water supply through there? 



Mt. Wood : We have a faucet over the trough that supplies 

 us with the hatching water, as we don't use these at all during 

 the hatchinsr.

Now, in selling trout fry, we have custonners who are often 

 very particular to get the exact number (it does not matt'er 

 whether they are selling at $1.50 or $3), and I always like to have 

 a customer that way. I wish every customer would count his pur- 

 chase. It bothered me a great deal to count the fry, and I rigged 

 up something of this kind (Fig. 4), which is much better than a 

 dry measure and a tin dipper, and we use it in this manner: I 

 set it on the bench and fill it with water, and I put the measure 

 under here, and I count out a thousand fry or tw^o thousand; per- 

 haps five thousand — of course putting those in a pool by them- 

 selves; then take those out with a net and put them in here and 

 measure the water which they displace. Now, it does not matter 

 whether I take one-half or just a few at a time; if I find 5,000 in 

 there displaces one-half pint of water, why, I think it is pretty fair 

 to judge that half a pint of water displaced is a fair estimate for 

 5,000 fry. 



The President: Any inc|uiries about the measure?
