In discussing this matter lately with Mr. A. O. 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 bea 
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 Lucernarva 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 Fritillarva 
furcata, not previously recorded, and a form of Ovkopleura 
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 College,
