and asbestos mines. About Brighton there are lots of to nearly 1000 feet. At Hetford Mines there is a just new development of asbestos. Half the houses are new. The mines are on each side of the track and one surface workings. One and even greater asbestos mines at Black Lake, here it is quite mountain- ous. Between Glencairn and Lake Gilmour are one out of the lots and in an undulating slightly farmed region. This does seem to be region of the watershed. Many are lots. Are the lots about Black Lake to be regarded as the barrier on the western side of which are the Mines Queenin depicts? The Atlantic Ordovician is of course in both sides. I see how no lots to the west, and to the east of the lakes. At Dundas Junction low lots appear to the front.
