this reason it secms that the fry of cod, on the younger stages, do not 
occur in greater multitudes at either of these places. 
The results of the investigations on the shores of Norway, in Scotland, 
and in Denmark, consequently, agree with one another as well as possible, 
and we cannot doubt their correctness, however strange it may seem that 
the cod, certainly, spawns in our seas, although its fry is not found here 
for several months after the spawning-season. The explanation of this fact 
must most certainly be looked for in the natural conditions caused by the 
salinity and the currents. The latter carry the eggs away from the inshore- 
"waters, before they are hatched, at any rate before the young are so large 
that they can resist the current, and are able to remain at a certain place 
in spite of the same. Such currents, going out of fjords and shore-waters, 
have now been pointed out by Hjort and Dahl in Norway, and we know that the 
southern current is predominant in our seas through the whole spring. It 
must be this current which carries the eggs and the tender pelagic fry out 
of our seas; already in 1892 I supposed this to be the explanation of the 
disappearance of the fry from Fænø. — How the fry again comes into our 
waters from the sea, in the month of August, is another question. It is, 
however, scarcely fry of the same eggs that have been laid there, which 
then returns; for we must suppose that the eggs are carried by the Baltic 
current through Skager-Rack up west of Norway, perhaps; but the currents 
which arrive at our shores in August, come from the southern parts of the 
North Sea and carry along, probably, fry of the North Sea cod. 
What I know, at present, of the fry of the cod in the North Sea, is 
not much. We have tried several times to find it off the western shores 
of Jutland; through Thyborøn, we have gone out trawling in the neigh- 
bouring waters, on board the Sallingsund, as also in the steam life-boat Vest- 
kysten; but we never found a single young cod on these expeditions, though 
we sometimes found the fry of whitings im multitudes. In 1899, Mr. Chr. 
Levinsen, M. A., explored the western shores of Jutland, looking for the 
tender fry of cod near land, at places especially adapted for it. At Esbjerg 
he found some of the fry of the year. At Hirtshals thousands of young 
whitings were taken, but very few young cod — 3 altogether. At Klitmøller 
he got none; but between Lild-Strand and Bulbjærg, where there was 
vegetation, he got a number of them, mostly 3—4 inches long. Among 
the sand-banks on the open shore, he tried some hauls with a hand-seine, 
but here he found only the fry of plaice. 
The conditions near land, on the western shores of Jutland, were, con- 
sequently, not very different from those within the Skaw, with regard to 
the frequency and the size of the fry of cod. Certainly, the bulk of them 
must live somewhere else. — Among other things, to get an opportunity 
of investigating the fry of codfish in Scotland, I made a trip over there 
together with the Norwegian Dr. J. Hjort, in 1899, in the month of July, 
and obtained permission to use the fishing-steamer The Garland for four
