12 
days, for the purpose of these investigations, for which permission I hereby 
thank The Fishery Board for Scotland. As we did not know, however, 
where the fry was to be found, the days passed quickly m looking for it 
only. Not till late on the last day, when we had worked our way far 
westward among the islands west of Scotland, consequently near the open 
Atlantic Sea, we took the tender fry of codfish, mostly of the green cod and 
the pollack, whose fry I never saw in Denmark, but also 8 small cod, the 
smallest of which were only a little more than one inch in length. 
I had no doubt that I was here near the dwelling-place of the tender 
fry of the cod, but unfortunately The Garland was no longer at our disposal. 
The fry of the cod in Denmark, however, scarcely comes from the 
western shores of Scotland, rather from the eastern shores of England, 
where the fry is also living; but most likely, I think, we must look for it, 
pelagically, in the North Sea itself. As yet, however, nobody has looked for 
it here; the idea did not present itself till Hjort proved that rather large 
multitudes of fry can live far from land, and far from the bottom.”) More- 
over, it does not seem to be the tender fry only that can live at these 
places in the water, for Hjort has also caught a few cod, as long as 35 
inches, on fishing-lines, on great depths of the sea. — 
We have now followed the cod through the first year of its life, as 
well as it can be done in the Danish seas, and have seen that the fecundated 
spawn, which is shed in the spring, disappears, and that the fry does not 
begin to appear in numbers till August, when the fish is 2—3 inches long. 
We have seen, further, that this fry in the next spring, consequently when 
it is one year old, has reached a length of 3—8 inches, and at that time 
is to be met with near land, on the zostera bottom, along our shores and 
in our fjords. We shall now follow this group through its after-life.. We 
found it, as above mentioned, in herring-seines, at Slipshavn, in March & 
April 1900, and stated that it was not to be found then in the deeper parts 
of the Great Belt. In June, several may still be found at Slipshavn, but 
some have then gone out on the deep. For out there we now get, on the 
hooks, not a few cod, as small as 7 inches in length, while in the month 
of March there were only 2 under 11 inches in length. They have also 
grown not a little, and continue to grow through the whole summer. 
In the autumn 1900, the smallest fish of this group were c. 7 inches, 
and the largest had already amalgamated with the older group, so that it 
was difficult to distinguish between them. Though thus, certainly, an 
emigration of small cod is going on in the summer time, from our shallow 
waters to the deeper parts, more particularly from the waters which are 
intensely heated by the sun, consequently the shallowest ones, this migra- 
tion is not of long duration; for already in September, nay, at a few places 
even in the end of August, when the nights become longer and dark, the 
=) Mc. Intosh, however, mentions the finding of one (loc. cit.).
