on the natural spawning beds, to New Zealand. We find also 

 that those eggs were successfully hatched there, and from this 

 small stock a beginning was made, and there seems to be little 

 doubt that from these eggs trout originated in New Zealand. So 

 successfully was the work carried on there, that the New Zealand 

 Government very wisely took it in hand, and the result was a 

 considerable importation of ova into the colony. 



Take the state of things in New Zealand to-day, and what 

 do we find ? Why, that the rivers of that country are, many of 

 them, full of magnificent trout that have grown beyond all expec- 

 tation. Trout-culture in New Zealand is a grand success. A 

 friend, writing to me from Tasmania, August yth, 1 890, says : 

 "The English brown trout that have been acclimatized here have 

 done remarkably well, and attain a great size." 



So then, in Tasmania also, trout-culture, though carried on 

 under the great difficulty of importing ova from Britain at a time 

 when its treatment was but very imperfectly understood, has 

 proved a decided success. 



In the United States the rivers of the Pacific Coast which 

 contained no shad, were successfully stocked with those fish by 

 transferring ova from the East Coast rivers. At first a million | 

 ova were carried in suitable apparatus, the incubation going on | 

 during transit. This proving a success, several cars were run 

 conveying five millions each, and by means of these ova the 

 rivers of the West Coast were stocked. The fish, which are pro- 

 lific, multiplied very rapidly, and had become so plentiful that 

 they were sold at three cents a pound. 



In 1886, a quantity of the ova of the smelt (Osmerus mordax) 

 were sent to Cold Spring Hatchery, on the north of Long Island. 

 They were hatched and turned out in Cold Spring Harbour, and 

 in two years a number of fish from these eggs were taken in 

 Oyster Bay, which adjoins the harbour on which the hatchery 

 stands, and into which they were turned, and they have also been 

 seen in the streams. 



Great success has in very many instances attended the plant- 

 ing of fry in the United States as well as in Canada. Had 

 " fully eyed " ova been judiciously planted in artificial beds, 

 probably the results would have been more satisfactory still. In
