elsewhere. It has also been stated that in the vicinity of the 
Penniac stream, a branch of the Xashwaak, in York county, 
vertical holes in the Carboniferous sandstone exist of such a 
character as to permit of a man beings lowered into them to a 
depth of fifty feet or more. In the Corbett's brook region, near 
Fredericton, but at a considerable distance from the caves de- 
scribed above, is a remarkable depression, the origin of which 
is problematical. It is said to be in the general shape of a square, 
with vertical rock walls or faces, each about fourteen feet wide 
and about fourteen feet deep. The bottom of the depression is 
filled with earth, on which small trees are growing. 
In the fissured or cavernous-like character presented by the 
millstone grit formation of XTew Brunswick, this recalls that of 
the same formation in portions of Kentucky, \"irginia and 
Tenessee, where similar holes abound in the escarpments of 
stream valleys, and are known as “ rock-houses.” There is no 
evidence of their having been employed in X"ew Brunswick for 
human occupation, unless it be in the case of the big cave on the 
Northwest Miramichi already described. 
I have been informed that in a deposit of apparently recent 
origin on the northern side of Swan Creek lake, in Sunbury 
county, there occur several curious holes. The bluff is about 
forty feet high, and is composed of a hard clay, filled with a great 
variety of pebbles. The holes run in horizontally at least eight 
or ten feet, the openings being about two feet wide. In front of 
these openings is a narrow ledge, or path. It is said that these 
holes are the homes of raccoons, and, by their appearance, they 
being quite round and smooth, it looks as if they had been 
actually hollowed out by these animals. 
To the above notes may be added the following, kindly fur- 
nished by Prof. Ganong, and which may at least suggest points 
for further exploration : 
From Mr. IF. E. S. FlcwcUing, Waterford, Kings Co. 
“ A noted ice cave near the village of Waterford, where ice 
keeps all summer. Eight deep holes or bottomless pits two or 
three miles from village.”
