..Report on the building and ornamental stones of Canada, volI-V . d and the forks.

While smallamounts of ])rown stone could still Ije obtained in the old quarries at theForks of the Credit, it is questionable, unless economic conditions changematerially, if these quarries will ever be reopened on any considerable face is practically quarried back as far as possible and the old tunnelshave broken down. To reopen these tunnels would recjuire a large initialoutlay, the return of which would be extremely doubtful. It is possible,however, that the demand for crushed stone will become so great that thewhole of the overlying Niagara limestone may be made into a marketableproduct. In this event, beds of brown stone will be available for easy ex-ploitation. y. 1 1 i ;? J ^^ \ /r ri i 1 i i m l r Vli ? ^m ^ ^ , i V o 17 Plate XLIV. Medina Sandstone withoverburden of Niagara Limestone,Forks of the Credit. 159 Northward from the old quarry, on the east side of the Cataract branch,the country does not seem to rise materially above the level of the sandstone;it is possible that prospecting in this direction might reveal beds of goodstone under an amount of overburden capable of removal. Such exposuresas appear towards Cataract, and also towards Belfontain, do not indicate,however, that the l)rown variety extends beyond the immediate vicinity ofthe forks. A general view of the cuesta at Credit forks is shown in Plate XLIII;the heavy burden of limestone coveiing the good stone is shown inPlate XLIV. Literature:—Geol. Sur.
