Abstract

Discussion. sir Robert Sir R. RAWLINSON, President, in proposing a vote of thanks to k~w l i n s o n. the Author, said that the question of economy in getting and dealing with coal was of the greatest importance. The margin of profit, as he knew from experience, between the production of coal and its sale was very small. In a large concern with which he had been connected for many years, with an occasional out-turn of 20,000 tons per week, the proprietors had derived small benefit, nearly everything having gone in working expenses. The question of working costs was therefore worthy of careful consideration.
