the young fish larva3 after hatching, Mr. Dawson and I 

 visited in April the hatchery at Dunbar, an institution 

 estabhshed by the Fishery Board for Scotland, and very 

 similar to our own hatchery in equipment and in purpose. 

 There we were shown, by Mr. Harold Dannevig, how the 

 millions of young plaice were kept only a few days, or at 

 most a week, and were then transferred to the upper parts 

 of Lochfyne on the west coast — an operation which is 

 conducted with very little loss. I sent a special report on 

 the visit to Dunbar to the Chairman in April, and this 

 was printed as an appendix to Mr. Dawson's quarterly 

 report in June. Many of the little details we saw at 

 Danbar may be useful to us in our further work at Piel. 



Although it was Mr. H. Dannevig at Dunbar who had 

 been most successful in keeping and feeding the young 

 plaice, still it must be remembered that those he dealt 

 with were a comparatively small number of isolated 

 specimens, and not the bulk of the season's hatching. 



We propose, then, to continue our rearing experiments, 

 but only to make use of the odd hundreds and tens — 

 setting free at a very young stage (as they do in Scotland 

 and America) the round millions and thousands. I do 

 not say that I regard this as absolutely satisfactory. It 

 still leaves in doubt the ultimate fate of the fry set free. 

 We do not know what proportion of them are killed off at 

 early stages in the sea, although we suspect that propor- 

 tion to be a large one. But it is the only practical method 

 until we determine by further experiment the conditions 

 under which it is possible to rear large numbers of larvae 

 through their metamorphosis into small fishes. 



We are certainly greatly retarded in our work at Piel 

 by the want of a large open-air tank, which could be 

 used as a spawning pond. Of the various schemes that 

 have been before the Committee of late years in regard to
