Original copies in printed paper covers are filmed beginning with the front cover and ending on the last page with a printed or illustrated impres- sion, or the back cover when appropriate. All other original copies are filmed beginning on the first page with a printed or illustrated impres- sion, and ending on the last page with a printed or illustrated impression. The last recorded frame on each microfiche shall contain the symbol — ^> (meaning "CON- TINUED "), or the symbol V (meaning "END"), whichever apolies.

Those too large to be entirely included in one exposure are filmed beginning in the upper left hand corner, left to right and top to bottom, as many fnmes as required.

NOTES ON GOLD AND SILVKR MINING IN THE PROVINCE OP QUEBEC. By John Feaser Torrance, B. A., Member Can. Soc. C.E., and Member Am. lustitutt; M.E. It is too much the fiishion with our local capitalists to seek for pro- fitable mining invcKtmonts as far a.s possible from iiome in British Co- lumbia, Colorado, the Black Hills or even in Mexico, while totally iiinor- ing tiie vast wealth of precious metals lying neglected at their very doors. I'erhaps a brief resume of some of the well-established facts about these resources might prove of service to counteract this ten- dency. Quite recently a very valuable report on this subject drawn up by my friend. Dr. 1{. W. Ells, LL.D,, etc., was publislied in Vol. IV of the New Series' of Reports by the Geological Survey of Canada. It is a matter much to be regretted that the general public rarely consult tiicse volumes. N-^ ! )ubt this arisi^s in part from a vague impression that such reports uust necessarily be too technical for any but trained geologists to eoiiipreliend, but especially from the size and absurd price of the volumes and all lack of public advertising of their contents. In this paper 1 propose to use freely the tacts so carefully collected by Dr. Ells and the other officers of the Survey, in the iiope that they may thus reach some readers not familiar with the publications of the Geological Survey. Some notes of my own observations and experiences in this mining region are added. My faith in the mineral resources of our central provinces was well grounded by Principal Dawson. It was strengthened and confirmed by the lectures of the famous geologist, Von Cotta, at tlie Saxon School ot Mines. He pointed out very clearly that the forces to who.se influ- ence we trace the formation of ore-dtposits have been operating ever since tlie earliest geologic ages. And he drew the logical conclusion that (other things being equal) the oldest geological formations should be the richest in valuable mineral deposits, because they have been subject to the action of those forces so very much longer tlian more modern Ibrmations. As these pahoozoie roeks are more widely distributed in tliis province and Ontario than iir almost any other country, we might feel reason- ably certain of the existence of many rich deposits of the precious metals and other minerals of economic value — even before such deposits were actually opened. Comparatively little prospecting for minerals was carried on in Quebec until quite recently. But the successful development of our phosphate mines and tlie more recent exploitation ol'our valuable asbes- tos deposits lead me to hope that brighter days may be at hand for our gold and silver mines also. The first published report of the existence of alluvia! (or placer) gold on the (Jilbert River in Beauce Co. appeared as far back as 1835-— sixteen years before the first samples of gold dust and nugi^etB from Australia created mah a profound s- isation in Great Britain. It lias always puzzled me why the nuggets and dust from Beauce Co. and Ditton never produee
