28 SINCLAIR ON PISCICULTURE. 



The white and yellow water lily, the pickerel, and other lake 

 weeds of this Province, are identical with those of Great Britain. 

 There is a far greater diversity in the land plants and shrubs, which 

 are indigenous in the two countries, proving that the thermal condi- 

 tion of their waters approximate much nearer than their atmosphere. 



It is probably owing to higher temperature in summer, that 

 many of our lakes have few or no trout in them. For this reason, 

 they would be all the better reservoirs for other kinds of fish. 



For instance : no one would now take the trouble to wet a fly m 

 that fine sheet of water, the lower lake at Dartmouth ; but were it 

 stocked with fish, perhaps less esteemed than trout, it would afford 

 healthy amusement to many who may not be adepts in the more 

 scientific branches of angling. Enjoyment is only relative, and 

 there are not a few who take as much interest in the bobbing of a 

 cockney float, as in the rise of a pound trout ; and even the ex- 

 perts might condescend to enjoy surer, though slower sport in the 

 summer evenings, at a season when the trout, sickened with heat, 

 refuse to take. As for the rising generation, they would be happier 

 and better spending their spare time dibbing for roach, dace, tench, 

 carp, and bream, than idling at home, or in city or town. 



It would require a naturalist of practical experience to decide 

 Avhether the white perch of America is the same as the British 

 perch. It is not likely. The British perch, in all considerable 

 lakes, grows to a very large size, and would probably do so here, 

 where the native perch rarely attains the weight of two pounds. 



Without pretending complete exactness, suggestive lists of fish 

 are appended to this paper. 



Possibly a correspondence with the Acclimatization Society in 

 Great Britain, might lead to some results in an interchange of fish 

 or spawn. As the delicate salmon roe has been transported and 

 hatched successfully in the Antipodes, there could not be any diffi- 

 culty or much expense, attending experiments of the same sort with 

 other fish, by means of the mail steamers. The gaspereau would 

 almost certainly thrive in Loch Awe and similar lakes, accessible to 

 and from sea, and fed by a diversity of rivers and streams ; and 

 our trout, sahno fontinalis, would be no mean acquisition to the 

 British lakes. 



It is remarkable that the lithographic history of the ancient 

 world reveals the fact, that there was then a difference of the fish
