THE U. S. FISHERIES STEAMER ALBATROSS. 



45 



Incidentally collections were made at a number of stations en route 

 to Panama from San Francisco. 



During the cruise there were made 203 hauls with plankton nets. 

 Of these, 134 were surface hauls, 65 with large nets and 69 with small 

 Kofoid nets; 54 were intermediate hauls (these exclusive of 4 trials 

 with the Tanner intermediate net and 1 with the Culm-Petersen), in all 

 of which Kofoid nets were used in conjunction with larger nets; 15 

 were vertical hauls. Forty-three hauls were made with beam trawls. 

 Of these, 30 employed the Albatross-Blake trawl, 2 the 9-foot, 14 the 

 8-foot, 7 the 6-foot, and 7 the 5§-foot. In 5 the 8-foot Tanner frame 

 was u<,o(\ and in the remaining 8 the 8-foot Agassiz pattern. In 10 

 of the 43 hauls the net was either wrecked or upset. The tangles 

 were used once in a deep haul, but made no catch. The soundings 

 numbered 111. 



The Albatross' regular series of dredging and hydrographic sta- 

 tion numbers were maintained in this cruise. Through an error in a 

 previous cruise the hydrographic series as originally published in 

 the Memoirs of the Museum of Comparative Zoology does not cor- 

 respond with the vessel's corrected record; an additive factor of 301 

 is required for all of the hydrographic numbers there published — 

 thus station H. 4504 should be H. 4805, etc. This correction, which 

 applies only to the hydrographic stations, however, is necessar}^ to 

 prevent a duplication of the vessel's numbers.
