The American Investigations of the Habits and 

 Migrations of the Mackerel. 



Since its first foundation the United States Commission of Fish and 

 Fisheries has paid great attention to the habits and movements of the 

 migratory fishes, more especially of those of the mackerel and men- 

 haden. In the early years of the Commission an endeavour was made 

 to obtain information by the issue of circulars to fishermen and others, 

 who were likely to be in a position to observe the movements of the 

 fish. In this way a large amount of material was got together, and was 

 embodied in two comprehensive memoirs, published in the IJeport 

 of the Commissioner : — 



(1) "The Natural and Economical History of the American Men- 



haden," by G. Brown Goode. Commissioners Report, 1877, 

 pp. 1-529. 



(2) " Materials for a History of the Mackerel Fishery," by G. Brown 



Goode, Joseph W. Collins, Pi. E. Earlle, and A. Howard 

 Clark. Commissioner's Report, 1881, pp. 93-531. 



The information, however, so obtained was not of an altogether 

 satisfactory nature, and it was seen that if the various problems pre- 

 sented were to be satisfactorily solved, special investigations for that 

 purpose would have to be made. 



It was largely with a view to undertaking researches into these 

 questions that tlie schooner Grampus was built for the Commission. 

 This vessel was completed in 188G, and since that year she has been 

 very largely employed in such work. 



The Grampus is a two-masted, schooner-rigged vessel, 90 ft. long over 

 all, 22 ft. 2 ins. beam, and 10 ft. depth of hold ; her registered tonnage 

 is 83 '30 tons. She is supplied with all kinds of fishing appliances and 

 scientific instruments suitable for the work she has to do. 



The appended extracts from the Commissioner's Reports, issued since 

 1887, will show the various steps which have been taken to investigate
