in our seas except in its season ; but again, like the mackerel, 

 it is too thorough a nomad to stand the confinement of an 

 aquarium. And those of you who wish to see either of 

 them alive must seek for them in their native haunts. 



DISCUSSION. 



Professor BROWN GOODE said he had heard some 

 complaint that there were too many scientific men on the 

 platform in these conferences, and too few practical men, 

 but every one would agree that Mr. Cornish had shown 

 that he had a thorough practical acquaintance with the 

 subject, whilst he had used a thoroughly scientific method 

 in his deductions. He had listened with great pleasure 

 to the Paper, having been for some years paying special 

 attention to the mackerel fishery in the United States. 

 That fishery was one of the most important in the 

 American waters. The produce in the year 1880 was 

 about 132,000,000 pounds. It employed about 470 of 



from Mr. R. Pollard, of Wadebridge, a gentleman largely interested in 

 the pilchard fishery. He has advised me that the earliest shoals of 

 pilchards which arrive annually in the Bristol Channel come in enor- 

 mous quantities from the north-west (or direction of the coast of 

 Ireland), and after hanging about in the deep water for a day or two 

 in u Mother Ivery's Bay " (east of Trevose Head, see page 131) break 

 up and go to the westward in small shoals, and pass St. Ives and 

 round the Land's End into the English Channel. 



Thus our two seasons for pilchards are apparently accounted for. 

 Mr. Pollard notes the very curious fact that, after a large shoal of 

 pilchards has broken up each small shoal formed from it keeps so 

 much together, and to itself, that if portions of two shoals are captured 

 in one haul they do not mingle, even though they may remain in the 

 seine for some days. This fact, however, depends on a solitary 

 observation. It but rarely happens that portions of two shoals are 

 enclosed in one shot.
