MAEINE BIOLOGICAL STATION ON PUFF[N ISLAND. 25 



In discussing this matter lately with Mr. A. 0. Walker, 

 he suggested that without going so far as a definite scheme 

 of artificial cultivation, a good deal might be effected by 

 selecting as breeding grounds certain portions of the coast, 

 say one mile in length and extending from the shore out 

 to a depth of a few^ fathoms, on which large stones should 

 be put down a hundred yards or so apart in order to prevent 

 any trawler from working on those areas. This would be a 

 very inexpensive method of making what would probably 

 form an admirable and safe breeding ground for both 

 shrimps and fish. 



Other Investigations. 



Mr. Chopin of Manchester did some collecting work at 

 the south end of Isle of Man in August, and succeeded in 

 finding Lucernaria which had not previously been re- 

 corded in our district. He also made a collection of 

 sponges which Dr. Hanitsch, who is examining them, 

 reports will probably be found to contain 2 or 3 species 

 new to the neighbourhood. 



Mr. G. Swainson of St. Anne's has been indefatigable 

 in tow-netting at night from the end of the pier, and has 

 been rewarded by the capture of a number of interesting 

 forms of surface life, including the Tunicata FritiUaria 

 fiu'cata, not previously recorded, and a form of Oihopleura 

 with a remarkable investing test or "Haus" on which 

 Mr. Swainson read a paper at the Cardiff meeting of the 

 British Association. 



Specimens collected at Puffin Island and elsewhere 

 have, as usual, been distributed to our specialists, and 

 have afforded material for a number of investigations 

 which have been or will be shortly laid before the 

 Biological Society. A small collection of typical marine 

 Invertebrata has also been sold to the Yorkshire Colleo-e,
