574 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [84] 



utes resulted in the capture of a small dogfish on the cod-lines. The 

 position of this trial was lat. 37° 39' N., long. 74° 38' W. 



Leaving the position of the last trial, we worked to the northeast, 

 the wind varying from a moderate breeze to a light air from that quar- 

 ter. At 6.45 p. in., took bottom temperatures in 31 fathoms, and at 7 

 o'clock prepared to set gill-nets. The mackerel net was set at the sur- 

 face and the herring net 3J fathoms deeper. The vessel was hove-to on 

 the starboard tack and the net warp made fast to the mainmast. 



In the early part of the next day the wind increased to a fresh breeze 

 from the north, and later veered to the north-northeast. Hauled the 

 nets at 4 a. m., taking one branch herring in the mackerel net. At 5 

 o'clock got under way and kept off on a southwesterly course ; changed 

 course later more to the westward, with a view to making a harbor at 

 Hampton Roads to get a supply of water, of which we were in need. 



Passed Cape Henry at 3.30 p. m., but owing to a head tide and an 

 adverse wind we did not anchor at Hampton Roads until 6.50 p. m. 

 Immediately after anchoring I went on shore to get the mail and tele- 

 graph our arrival. 



D.— SUGGESTIONS FOR COLLECTING AND PRESERVING SPECIMENS. 



Additional instructions for making observations and caring for speci- 

 mens, which were prepared by the Assistant in charge of Scientific In- 

 quiry, were received. It may not be out of place to say here that it 

 has been customary on the vessel to carry out such routine as was or- 

 dered, since it has always been recognized that the value of the obser- 

 vations, as well as the importance of the collections as study material, 

 depends on the accuracy and completeness of notes on surrounding con- 

 ditions. The following is a copy of the orders and letter transmitting 

 them : 



U. S. Commission of Fish and Fisheries, 



Washington, D. C, April 27, 1888. 



Dear Sir : I send you, herewith, some suggestions for collecting 

 and preserving specimens, and for making observations, which have 

 been prepared by the Assistant in charge of Scientific Inquiry, and which 

 have been forwarded to me by the Commissioner. As I understand it, 

 you have been carrying on your observations in a manner similar to 

 that required by these suggestions, which you will attach to the instruc- 

 tions for the cruise that I forwarded to you a few days ago, and with 

 which you will comply so far as practicable. 

 Very truly yours, 



J. W. Collins, 

 Assistant, U. S. Fish Commission. 

 Capt. D. E. Collins, 



U. JS. Fish Commission Schooner Grampus, Fortress Monroe, Va.
