Scheme VIII (Jar. No. 15): to keep the young fish in 

 water taken from a fresli water pond. Water for this 

 purpose was taken from a pond of clear water from 

 which the villagers obtain their yearly supply of ice. 

 The fish survived the change 24 hours. 



Scheme IX. (Jar. No. 5) : A temperature test, the jar 

 being filled with spring water, kept constantly at a tem- 

 perature of 65 deg., by the addition of ice water. The 

 fish lived until 3 a. m. , on the 23d. 190 hours from the 

 hatching boxes. 



Scheme N (Jar No. 6): Temperature test at, 60,,deg., 

 and Scheme XI (Jar No 7), temperature test at 5a cleg. 

 It was found impracticable to keep the temperature at 

 these points, and the average in Nos. 6 and 7 was not be- 

 low 64 deg. In jar No. 6 the fish survived until 9 a. m., 

 on the 23d, 196 hours. Jar No. 7 seems to have on the 

 whole, been the most successful, the greater part of the 

 fish surviving until 9 p. m.. on the 23d, when they died, 

 all at once, after 208 hours of life. 



Scheme XII (Jar No. 8) : Temperature test at 50 deg. 

 On the 21st this jar was placed in the refrigerator, where 

 a temperature of 48 deg. for the bottom and 52 deg. for 

 the surface was attained, giving an average of 50 deg. 

 The young fish died in the course of seven hours. 



Scheme XIII (Jars Nos. 9 and 10): Temperature 

 best at 70 deg. This temperature was successfully 

 maintained, The young fish died at 3 p. m. on the 23d 

 after living 202 hours. 



It will be observed that in some respects the 

 best results were obtained in jar No. 7, the 

 majority of the fish living 6 hours after they had begun 

 dying in jar No. 3, though some individuals in 'No. 3 

 survived much longer than any in No. 7. It may be 

 that the mixture of pond water derived from the melted 

 ice hastened death in No. 7, for the experiment of 

 Scheme VIII shows that this water is injurious. The 

 results of Scheme III are probably the best, although 

 only a small proportion of the original number came to 

 the final best. The results of the experiment may be 

 roughly summarized aq follows; 



1, It has been shown that the young shad cannot be 

 kept alive in cans long enough to make a transatlantic 

 voyage of ten or twelve days. 2. The length of time 

 they can be kept in cans has been satisfactorily deter- 

 mined, being fr )m eight days and ten hours to eight 

 days and sixteen hours ; in individuals, extending to ten 

 days and twelve hours. The longes *;ime hitherto made 

 was that by Seth Green, who carried the young fish
