With the question of the protection of the lobster is involved 

 that of lobster culture. As has been shown in previous reports, 

 artificial hatching can be accomplished with a great measure of 

 success. But our experiments have led to the conclusion that 

 ordinary tank methods are not adapted to rearing. It is there- 

 fore recommended that further experiments should be made 

 on the American plan, and reference is made to a place on the 

 Northumberland coast which could be used for experiments, 

 and if these are successful, for finally being adapted for the pur- 

 poses of the district. 



The transplantation of mussels at Holy Island has been as 

 successful as could be expected, since the beds were not under 

 supervision. The bouchots were not strong enough to withstand 

 the heavy seas and currents. A consideration is given of the 

 drift of mussel larvse along the coast, and this appears to point 

 to a passive migration of larvae to the south. 



The question of the pollution of the Tyne has been the subject 

 of an important conference in Newcastle. The results of the 

 examination of samples taken by the " Evadne " in the river 

 show that the region opposite Newcastle is in a particularly bad 

 condition. This polluted zone is practically devoid of oxygen, 

 and is never entirely removed, only moving up and down with 

 the tide. Our experiments are fairly conclusive, but it would 

 be desirable on a succession of dates to sample a cross section of 

 the river at intervals during twelve hours. 



Miss Robson has prepared a Catalogue of the Hydrozoa of 

 the Cullercoats region, incorporating the records of Dr. Johnston, 

 Berwick, and Joshua Alder, Newcastle, with those she has made 

 during the past two years. She has not obtained twenty of the
