NOTES ON RECENT EXPOSURES IN THE SOAP- 
STONE ROCK, 
_ The drainage system now in course of con- 
Struction in this vicinity, known as the Arietta 
OcToBER 4th, 1902 
Street sewer, with its several branches, has 
exposed from time to time a series of sections 
through the soapstone rock, and brought to 
light many good specimens of the characteris- 
tic minerals, 
The south-west corner of Westervelt Ave- 
nue and Second Avenue was known asa local- 
ity for fibrous serpentine along time ago and 
some of our best specimens were obtained 
from there, so the progress of the sewer trench 
near this locality was watched with consider- 
able interest. When it was reached a seam 
of this mineral was encountered, striking 
diagonally across Westervelt Avenue, in a 
south-west and north-east direction, and large 
masses were dug out, from which I selected 
these specimens. They are not as fine and 
silky as many previously obtained near the 
surface. The fibres are more compact, but 
they are unusually long, and in this respect 
we have no other specimens which can com- 
pare with them assome are three feet and 
more in length. 
The compact texture and length offibre are 
doubtless due to the fact that the part of the 
seam froin which the specimens came was 
considerably below the surface and had not 
been subjected to weathering. 
Apparently the contractor thought that it 
had some commercial value as most of it had 
been thrown in a separate place and was 
subsequently packed in barrels and removed. 
Close to the serpentine seam was aband of 
massive green and red soapstone, unlike any- 
thing previously found cing she Soviqunity, but 
similar to some of /the disintegrated“ aock
