been held. The first two were in the Fisheries laboratory 

 and in the Zoology Museum at University College, Liver- 

 pool, in February and March, 1900. The next three were 

 at the Piel Hatchery in March, April and July, 1901, and 

 the remaining two were also held at Piel during last 

 April and May. 



I have no hesitation in recommending that in future 

 the classes be held at Piel. There are facilities in the 

 provision of fresh material, especially living surface 

 organisms from the sea, and in the study of the stages i?i 

 fish hatching, that can be given better at Piel than 

 anywhere else. 



For several reasons the classes must be held in spring. 

 During March and April is the most convenient time for 

 the fishermen themselves, it is the best time for obtaining 

 the necessary material from the sea, and it is the only 

 time when the fish hatching can be studied. 



Each class lasts for two weeks, and it is found that two 

 hours in the forenoon followed by two hours in the after- 

 noon, of continuous laboratory work is as much as the 

 fishermen can manage without strain, in each day. 



Ten men form a convenient number to teach at one 

 time, but we can accommodate fifteen, and classes of thai 

 number have been held at Piel. On one occasion at 



Liverpool we had sixteen in the chiss. 



The fishermen can be accommodated in lodgings at Roa 

 Island during the fortnight, and the allowance paid lo 

 each man selected for a class is £-3 to meet his travelling, 

 living and any other expenses. This money has been pro- 

 vided by the Technical Instruction Committee, and with 

 each £100 for the men £20 has been given to defray the 

 expenses of furniture, fittings and material for the class. 

 No part of the grant made by the Technical Instruction 

 Committee has in any case gone to the teachers.
