cold layers of 1°5 in deep water up in the fiord, while the temperature at corresponding 
depths outside (off Vardö) was 4°. 
However great the importance of these conditions, they must nevertheless, as re- 
gards their connection with the points here discussed, be considered as local questions; 
questions of great significance in as much as they concern the locality of the fishery, but 
not as regards the extent of the total yield. All the facts herein set forth would seem to 
indicate that the great principal results are first of all dependent on the size of the stock, 
and that investigations in this direction may and should be carried out according to 
the method which has here been in part laid down, and which may be perfected in the 
course of future investigations. As regards the continuation of the work, this must 
depend upon how far the results set forth succeed in arousing sufficient interest and 
confidence to warrant the establishment of the organisation requisite for undertaking 
the same. | 
Investigations as to the Norwegian fisheries in the spring of 1914. 
The manuscript of the present work was written during the autumn of 1913, 
which precluded the inclusion of information concerning the fisheries and the stock 
subsequent to the spring of 1913. It is evident, however, that it must be a task of 
the greatest interest for the Norwegian fishery investigations to further pursue the 
questions here discussed, especially as to the state of the stock during the spring 
fishery of 1914, both as regards the amount of the yield, and the composition in 
point of size and age of the hauls. The information given in the present work was, 
with the majority of the figures, curves and charts therein contained, laid before 
the International Council for the Investigation of the Sea during its meeting at Co- 
penhagen in September 1913. It would therefore be of particular interest to com- 
pare the facts as then stated with the results of a subsequent year’s experience. 
This would furnish a means of determining how far it is possible, with the methods 
employed, to lay down, a year in advance, the principles upon which the situation 
in a following year should develope; in other words, a test of the reliability of the me- 
thod as a basis for prediction. And the year 1914 should, as already frequently men- 
tioned in the foregoing, furnish valuable information as to the longevity of the her- 
ring and cod, since the year class 1904 in this year attains the great age of 10 years. 
With these ends in view, great efforts have been made during the past months 
to procure a large amount of material consisting of observations as to the com- 
position in point of size and age of the large and spring herring, the Finmark cod 
and the Lofoten skrei. Herring samples have been obtained from the Sondre Trond- 
hjem and Romsdal districts during the large herring fishery, and throughout the 
whole range from Stat to Kristianssand during the spring herring fishery. Valuable 
assistance has been rendered in the course of these investigations by Mr. Eınar 
GIERTSEN, who has sent numerous expeditions to the localities concerned, and has 
exhibited the greatest interest in supporting the work by placing at our disposition
