OPERATIONS OF SCHOONER GRAMPUS.

example in that of the pollock, not 5 per ceiit. of the catch lived until 

 the vessel reached Wood's Holl, and the mortality to the other species 

 was always large. 



The Commissioner having decided to send the Grampus on a cruise 

 to the southern mackerel grounds, orders were issued for the work of 

 collecting fish eggs to be brought to a close and for the necessary prepa- 

 rations to be made to fit the vessel for the intended cruise. 



In concluding this report upon the operations of the Grampus it is 

 only just to say that the officers and men under my command have ex- 

 erted themselves to the utmost to carry on successfully the work in 

 which they were engaged. Hardships and dangers, which might in- 

 timidate and discourage men unaccustomed to the vicissitudes and per- 

 ils of a fisherman's life, were cheerfully borne, and no opportunity was 

 lost to obtain fish and fish eggs. Mr. D. E. Collins, while in command, 

 not only exhibited much energy in carrying out his instructions, but he 

 also exercised care and prudence in the mangement of the vessel, which 

 met with no damage whatever during the winter, though she was con- 

 stantly going in an out of crowded harbors, often at night and not un- 

 frequently in thick weather.

* For sounding we usccl an ordinary cotton fishing line, marked at every ten fathoms, and a deep-sea 

 sounding lead of 16 pounds weight. The depths given in this report may not on this account be 

 deemed absolutely accurate, but will not in any case vary more than a few fathoms — probably in no 

 case more than 2 or 3 fathoms— from the actual depth. The reason for using this method of 

 sounding was threefold : (1) It was not deemed essentially necessary to make accurate hydrographio 

 records ; (2) our " Tanner machine" was not ready to use, and consequently wo had to depend on the 

 ordinary line, and (3) it would be impracticable to use the machine, even if it was ready, in carrying 

 on rapid fishing operations, since the time required to make soundings, etc., would very much interfere 

 with the time absolutely required for fishing, and where the vessel has only a small force, as in th» 

 present case, it was necessary to adopt the most feasible method.
