Abstract
A USEFUL publication which has made its annual appearance is “The Canadian Mineral Industry in 1938” (Dept. of Mines and Resources, Mines and Geology Branch, No. 804. 25 cents). It gives the output of all important mines in Canada and the destination and use of the product. It is noteworthy that Canada, in its pitcjiblende deposit near the Great Bear Lake, shares with the Belgian Congo the source of nearly all the world's radium. The Canadian output has caused a considerable fall in the price of radium in recent years.
