156 BULLETIN OF THE UNITED STATES FISH COMMISSION. 
At 5.22 on the morning of the 19th we cast the trawl in 1,276 fathoms, 
bn. M. (latitude 39° 27' north, longitude 71° 16' west). It came up with a 
few specimens of fish, 1 squid, 2 octopi, a number of sea-urchins, brittle 
stars, 10 specimens Holothurians (Benthodytes) and a number of shells. 
Two more hauls were made during the day in from 1,163 to 705 fathoms, 
gn. M.and Oz., between latitude 39° 31' and 39° 42' north, and longitude 
71° 14' 30" and 71° 17' west, securing a number of blue hake, Macrurus 
Bairdii, 3 specimens of Geryon, etc. The last haul brought up a large 
number of skates 5 eggs. The surface net secured several rare speci- 
mens of crustacean, squid, etc. During the day several sailing vessels 
were sighted. 
At 6.15 p. m. we started for Wood’s Holl, arriving and making fast 
to the Fish Commission wharf at 9.50 a. m., September 20. The cruise 
was considered as a trial trip for the new boilers as well as for the 
sounding and dredging apparatus, all of which worked satisfactorily. 
A few rivets and one or two stay bolts in the boilers were found leaky, 
and they will be made tight by the contractor. 
The dredging and trawling record and the record of temperatures 
and specific gravities are appended. I wish to call attention to the lat- 
ter, as it presents a series of specific gravities from Baltimore down the 
Patapsco river and Chesapeake Bay to the sea, showing the gradual in- 
crease of saline matter in the water till it finally reaches the density of 
the open sea.
