at Rodvær. On dredging there over the great flats, I obtained quantities 

 of Herring roe at a depth of only 3 to 4 fathoms. During the first 

 days of March the Herrings went in towards the mainland, inside the island 

 belt, and were hemmed in with nets in the small bays in the neigh- 

 bourhood of Haugesund. 



From the Surface Chart (D), and my representation of the Winter 

 1894, in Chap. II, one will perceive that the North Sea Water at that 

 time ran in quite close to the land on the West Coast of Norway. The 

 saline contents of the surface were nearly 34 per 1000, and the tempera- 

 ture 5 degrees; there, doubtless, occurred minor changes in the saline- 

 ness between 30.50 and 34 per looo, the temperature 4.5 ° to 5 degrees, 

 but the conditions were, on the whole, very similar during February 

 and March. Under snch ciraimstances therefore a typical influxion may 

 occur close into the land. 



The fishing waters were again investigated from the i6th to the 

 19th April. The North Sea and Bank Water had then descended to a 

 depth of about 60 mètres, and above them lay a mighty layer of Baltic 

 Water of a salineness of 27 per lOOO on the surface. The fishing had 

 then been long concluded. 



At the close of January, and beginning of February of the Winter 

 then past, the water was of great saltness and warmth (4 ° Celsius). As 

 therefore, as mentioned in Chap. II, the Baltic Current reached the West 

 Coast the 8th and 9th of February, fishing was only carried on at Utsire, 

 and none inside of it (inside of it la}' fresher and colder layers, see PL I\", 

 Fig. 2). Later on in the month the Herrings »being hotly pursued by 

 cod and whales« went for a few days up to Røvær, but, otherwise, 

 herrings were only caught in deep water (according to report, about 40 

 fathoms) and no influx took place within the islands. 



From Chap. II we learnt that, on the West Coast, during the Winter, 

 the closest connection existed between the temperature of the sea and 

 its salineness, so that 



The North Sea Water corresponded to 5 " 

 - Bank Water — »— 4" and 3» 



and - Baltic Current — » — 2», i °, o " and — i ". 



We learnt, moreover, that in consequence of this, and from previous in- 

 vestigations of the temperature, one was able to conclude what the saline- 

 ness, the currents, had been, too, in former times, when the conditions were 

 studied by A. Boeck, 0. Jensen and 5. A. Buck '. These earlier measure-
