86 Thirty-Second Annual Meeting 



transit to the station there was absolutely no possibility of their 

 receiving any air in addition to that enclosed in the jar. 



Mr. Titcomb : What I mean by "comparison" is this: You 

 cannot comj^are them with the station eggs or the eggs you get 

 from the commercial hatcheries ; you have got to make yovir com- 

 parison in order to ascertain the relative merit of transporting 

 those eggs gTeen or young, by eyeing a part of them right where 

 they are taken, and then transporting the balance, getting the 

 comparisons from the same fish under the varying conditions. 

 Undoubtedly the wild trout of Sunapee Lake will yield a strong- 

 er trout than the station fish. 



Mr. Thompson : I only mentioned that in a general way as 

 it has some slight bearing on the subject. 



Mr. Hubbard : I might say that I have liad such good suc- 

 cess with the jars from the beginning that I have not tried any 

 other way of shipment, as for instance, in trays. 



Mr. Clark : How long have you kept the fish in the jars ? 



Mr. Hubbard : About eight hours. 



Mr. Clark : In our work on Detroit river, all our fish eggs 

 were moved from the field station to the hatchery, in cans. They 

 are sometimes taken in the afternoon and do not reach the hatch- 

 ery until the next forenoon, and are held in cans all that time. 

 The change of water while they are at the field station in tubs, 

 is made ever}' hour. When they are put in the cans it is not in- 

 tended that they shall be kept there longer than three hcMirs. 



Mr. Atkins: Is there no change made during that three 

 hours? 



Mr. Clark : Xo sir, except what little aeration there is in the 

 winter. I think in Mr. Hubbard's experiment if the water is at 

 a proper temperature there would not be a particle of difficulty 

 in sending them in those cans, if you did not have too many 

 eggs for the amount of water. 



Mr. Hubbard: They were in two-quart jars, whicli were 

 probably two-tliirds full of eggs. 



Mr. Clark: I tliink there is a point in the sealing Ijusiness. 

 I conducted an cxpcriuu'iit with fish along that line. 



Mr. L. B. Handy, South Wai'eham, Mass. : I take the eggs, 

 pour them right into the ]>an, not letting tlieni be in water over
