OUR INLAND FISHEKIES. 27 



Here fish of all kinds hunt and destroy it, and even 

 when full grown it is the prey of the grampus and

 that were it not for the machinations of man 

 his worst enemy sufficient of the species would 

 still remain to fill our rivers almost to teeming.

 nately here man has the power to protect it from 

 most of the perils it endures when left to itself in 

 the river, and at this particular point artificial pro- 

 pagation is a most valuable assistant. 



In this country we have as yet had but few 

 attempts made upon anything like an extended scale 

 to put into practice the art of pisciculture. Perhaps 

 those best known and of most importance have been 

 carried out at Stormontfield, on the Tay ; at Messrs.
