was found to answer every purpose in dredging or trawling at 
all depths down to 100 fathoms, and undoubtedly would do 
equally well at far greater depths. With a larger vessel, in 
heavy weather, or at very great depths, the rubber accumulator 
would doubtless prove advantageous, but it is quite superfluous 
for working in less than 500 fathoms, in moderate weather. 
Therefore, any party undertaking such dredgings as can be 
carried on with small vessels off our coast, need not encumber 
themselves with this expensive piece of apparatus, for which a 
ew fathoms of small or weak rope, applied in the form of a 
“check-stop,” may be substituted | 
Deep-sea thermometers, water-bottles for obtaining samples 
of the bottom-waters, and other physical apparatus, were also 
provided and frequently used. . 
Mr. Emerton was employed during the two months of active 
work in making drawings of the more interesting new and 
rare animals, from life. These drawings are remarkably accu- 
rate and life-like, and number nearly three hundred. hey 
constitute one of the most valuable results of the expedition. 
As Mr. Emerton had drawn large numbers of our common 
marine animals for us during the two previous years, a consid- 
erable portion of his time was this year devoted to the free- 
swimming larval stages of crustacea, ete., and to the smaller 
and less known species in various classes. The soft parts of 
many species of mollusks were also well figured. 
In consequence of the liberal codperation of Prof. Pierce, 
superintendent of the U. S. Coast Survey, and other officers o 
the Survey, the U. 8. Coast Survey steamer Bache was de-

One of the most interesting regions examined was 1n the 
deeper waters outside of Casco Bay, 15 to 30 miles southeast 
from Cape Elizabeth. To this region we made several excursions, 
and dredged at depths varying from 40 to 95 fathoms, the 
depth gradually increasing with the distance from the shore. 
In these localities the bottom was generally of soft mud, with 
more or less numerous, scattered boulders. On one oceasion we 
brought up in the trawl from 65 fathoms an angular boulder,
