of the district will depend as much on the direction and 

 force of the prevailing winds during the spawning period 

 as on the general direction of the tidal streams. And 

 since the prevailing winds during the early pari of the year 

 are from the W. and S.W., there will be a general drift to 

 the northern part of the district, and to a lesser extent 

 towards Liverpool Bay and the Ribble. The experiment 

 made by Prof. Herdman seems to prove what was indeed 

 conjectured by Mr. Ascroft, that the eggs from fish 

 spawning off Carnarvon and Cardigan Bays might find 

 their way into Lancashire waters. It might- have been 

 expected that many of these would go to the shallow 

 waters in the above Bays, but this experiment shows that 

 there is not sufficient in-draught into the bays from the 

 deep water where we may, not unreasonably, look for 

 spawning fishes, to produce this effect to any marked 

 extent The area, therefore, over which it is necessary 

 to trace the distribution of fish eggs and larva 1 seems to 

 he widened, and the experiments indicate the need for 

 further investigations of the southern, part of our extended 

 sea fisheries district.
