Gypsum in Ontario

"It is a truism that the metals, and particularly the precious metals tend to monopolize the attention of those interested £n the mineral industry. This is a tendency to be mildly, but actively and continuously combatted if we are to have a well-rounded mineral development." There are in the province of Ontario a number of industries centred about the non-metallic minerals. Too little is heard of the part these play in our industrial life. It is with the intention of showing what the gypsum industry is doing in Ontario that this paper is written. The writer lays no claim to any originality in the discussion and merely offers some material in an endeavour to assist in bringing about that 'well-rounded mineral development' sought for Ontario. M. Y. Williams in his "The Silurian Geology and Faunas of Ontario Peninsula and Manitoulin and Adjacent Islands"1 in discussing the industries dependent on the Silurian rocks of south-western Ontario points out that "the splendidly ordered gypsum mine at Caledonia, formerly owned by the Alabastine Company of Paris, and now owned by the Ontario Gypsum Company, is a revelation to the average man, who disconnects mining entirely with this part of Ontario". This region is better known as one of the richest and most thickly settled agricultural areas in Canada.
