ditions on which they depend. It was therefore necessary to 

 have a vessel capable of making investiga- 

 tions similar to those carried on by oceanic 

 expeditions, and at the same time suitable 

 for practical fishery experiments, which are 

 every year becoming of more and more 

 importance in the work of scientific re- 

 search. A ship of this kind, however, had 

 to be small, otherwise it was impossible to 

 reckon on sufficient means for its upkeep. 

 Accordingly the size we selected was that 

 of a first-class fishing trawler. Her length 

 is 125 feet between perpendiculars, and 

 she is of 226 tons burden ; her engines 

 indicate 300 horse-power, and can give her 

 a uniform speed of 10 knots; her coal 

 consumption is small, being about 5 tons 

 per twenty-four hours when going at the 

 rate of 9 knots, and she can carry in her 

 bunkers about 80 tons. As will be seen 



from Fig. 20 there is plenty of space on ftUy 



deck forward of the engines. The big 

 winch is placed here just abaft the hatch 

 of the storeroom, in which there is 

 cold storage for 10 tons of fish, and 

 stowage for appliances, instruments, cases 

 of glass bottles, etc. Forward of this 

 storeroom are the cabins of the engineers 

 and mates and the quarters of the crew. 

 Abaft the engines there is a labora- 

 tory on deck, and below there are cabins 

 and a messroom for the scientists. The 

 deck is perfectly clear on either side 

 of the deck-house, so that there is ample 

 room for working with appliances and 

 instruments. 



If we compare Figs. 20 and 21 we 

 shall get a good idea of the appearance of V^ \Z} 

 the deck of the " Michael Sars." On the 

 starboard side there are two small winches, 

 the forward one of 3 horse-power and the 

 aft one of i horse-power. The forward fig. 20.— Deck arrange-
