At the town of Perth's fisheries, again, the total produce 

 was as follows, viz. 



Salmon. Grilses. 



During ten years preceding 1798 31,536 6,070 



During do. subsequent to do. - 32,477 10,518 



INCREASE during the last period when 

 the stake-nets were in use in the 

 frith below .... 941 4,448 



A still more striking illustration perhaps, is afforded by 

 the Moncrieff fishery. During the last three years of the 

 first period, viz. 1795, 1796, and 1797, the number of Sal- 

 mon taken at that fishery was 6,356 

 While, during the corresponding years of the 

 second period, viz. 1805, 1806, and 1807, 

 when stake-nets were more extensively em- 

 ployed in the frith below than at any previ- 

 ous period, thejiumber taken, was - 7,398 



INCREASE on the last three years 1,042 



The results at other stations were similar. And although 

 no account of the produce, since the removal of the stake- 

 nets, has been exhibited or can be referred to, yet it is 

 perfectly notorious that the river fisheries have not, during 

 the period which has elapsed, been more productive than 

 they were previously. 



But it is unnecessary to pursue the inquiry farther.' Nei- 



shews, however, that for the purpose of instituting a fair com- 

 parison, the experience of a number of years must be resorted 

 to. And, accordingly, ten years was fixed upon in the Tay case, 

 by common consent.
