2. General exploration, such as faunistic work, the 

 tracing of areas of the sea bottom, the surveying of 

 spawning and rearing grounds, the determination of 

 the distribution of invertebrata and of fishes, and the 

 investigation of specific points upon which information 

 was required, such as the presence of full herring at 

 certain times in Cardigan Bay. The programme for 

 this work would necessarily be elastic, and could only 

 be undertaken when it did not interfere with the fixed 

 observations under 1. 



Provisional Arrangement of the Work. 



It is proposed that in each month the first week 

 should be devoted to work in the important waters round 

 the Isle of Man, the second to the dee]) water off 

 Anglesey, the third to Cardigan Bay and the coast of 

 Wales, and the fourth to the shallow in-shore waters 

 of the Lancashire and Cheshire coasts. 



First Week. 

 First Day. — Start from Fleetwood and steam west till 

 the 20 fathom line is reached, about 35 miles. This is 

 the region known as the " Hole,'" a very important 

 spawning ground for plaice and other fiat fish. The 

 vessel should now take three hauls of the fish trawl. 

 each of two hours duration, along lines running east 

 and west, at depths of 20 to 25 fathoms. After the last 

 of these, a short haul should also be taken over a part 

 of the same ground with a shrimp trawl, in order to 

 obtain smaller fish and compare results. Plankton nets 

 will also be used simultaneously with the trawl, and 

 physical observations will be taken at the beginning 

 and end of each haul. The vessel will lie for the night 

 in Port St. Mary Harbour.
