~ 6 localities, in 1000 to 1600 fathoms, the oti is cov- 
ered with or largely com “isin of hard, very irregular, flattened, 
crust-like concretions of clay and iron-oxide, wi ith more or less 
manganese-oxide in the crevices and worm- burrows with which 
mey are filled. At some localities a barrel-full, or more, of 
uch masses were brought up, varying in size from a few 
ssohoes up to 20 pounds or more in weight and from one inch 
to six inches in thickness. 
The following are some of the localities where such material 
occurred : 
Station 2208, in 1178 fathoms, N. lat. 39° 83’, W. long. 71° 
‘15. Large quantities of hard crusty ferruginous clay. 
Also a rounded granite bowlder, weighing over 20 pounds. 
Station 2228, in 1582 fathoms, N. lat. 37° 25’, W. long. 
TOSS Large quantity of irregular crusty and. vee 
concretions and masses of ferruginous clay, with considerable 
black manganese-oxide lining the holes and cracks. The lower 
side of many of the masses consisted of sticky bluish clay. 
It was estimated that about a ton of this material came 
up. There were adhering to these hard masses some corals, 
gorgonians, hydroids and bryozoa, with the brachiopods, 
Discina branes and Waldhemia cranium, in considerable 
number 
Roanded bowlders and pebbles of granite, gneiss and other 
crystalline rocks occurred at a number of stations. One bo wl- 
der, station 2208, is referred to above. The sg ee are 
other localities: station 2195, in 1058 fathoms, N. lat. 39° 44, 
W. long. 70° 03’. A rounded granitic bowlder, at four 
inches in diameter. Its surface was covered with adherent 
species of foraminifera and some annelid-tubes. Station 2226, 
in 2021 fathoms, N. lat. 37° 00’, W. long. 71° 54’. A large 
number of pebbles and small, rounded bowlders of granite, 
porphyry, etc., and some coal cinders. The pebbles were more 
ess covered with adherent foraminifera, bryozoa, etc. 
Scattered bowlders and pebbles have also occurred at many other 
localities along the inner edge of the Gulf Stream. These 
have probably all been sasried out there by ice from the adja- 
cent coasts, in spring. 
A curious instance, quite unique in our experience, of the 
occurrence of abundant relics of human handiwork was ob- 
served this year. At station oy ek in 1587 fathoms, N. lat. 
39° 03’ 15”, W. long. 70° 50’ 45”, beneath the Gulf Stream, 4
