90 THE FISHERIES. 



which the river Tolka discharges itself. It is ma- 

 nifest, that with little difficulty or expense, salmon- 

 fry, in any quantity or profusion, could be produced 

 in the Tolka, and be then, at the proper periods, 

 discharged into this large tract of sea-water, and 

 there retained, by suitable arrangements, for a few 

 weeks, during which they would acquire strength, 

 and become " acclimated" gradually ; and, above all, 

 be protected, at that period of their growth, from 

 the various dangers which await them, from natural 

 enemies, on their first ingress to the sea. We do 

 not, however, think that the neighbourhood of a 

 large city is the suitable place for such experiments 

 — particularly when so many pure mountain streams 

 and secluded localities can be so easily selected. 



In the small streams which discharge themselves 

 into the sea at Bray, near Dublin, and which are 

 excellent spawning streams, frequented by their own 

 native salmon, salmon-fry could be produced in any 

 conceivable profusion, and be discharged at the pro- 

 per season into a suitable enclosure, accessible to the 

 sea- water ; and be thus protected, at all events for 

 some portion of their existence, in their new element. 

 But we shall select a locahty, where this experi- 

 ment, or rather this series of experiments, might be 

 tried on a large scale, and at a small expense, and 

 under the most favourable conditions. We mean 

 that large reach of sea or tidal water, which flows 

 up near the town of Wicklow into a cul de sac, 

 forming a large salt-water lake, and into which the
