The data were derived by using all the information available for the last 10 years to establish trends by linear regression analysis. The full 10-year figures were available for the United States and Canada, and at least 4 years were available for each of the other countries. If each of the major consuming countries kept a near-constant share of an expanding market, the result would be a straight line, as shown by Canada. The U.S.S.R. and Japan typify those countries whose consumption rate has increased faster than the world production rate. The United States and the United Kingdom have gone -the opposite way. The United States, with a remarkably stable consumption rate, is taking a smaller share of the expanding market, and it is apparent that it will soon be supplanted by the U.S.S.R. as the world's largest consumer, if this has not already happened. The same kind of analysis of Canadian data can also be informative, as shown in figure 2. Canada is both the world's largest producer and exporter of asbestos, and a major consumer as well. The marked divergence of the value and production lines shows graphically the inflationary trends. The upward slope of the production and export lines is indicative of the expanding world market. The slight divergence between the production and export lines illustrates that Canada's consumption growth rate exceeds that of production and that an increasing amount of Canadian asbestos is being used domestically. Australia.—The Woodsreef mine and mill began operation in January 1972 and had such promising prospects that its parent Canadian company (formerly Pacific Asbestos) is now officially Woodsreef Minerals, Ltd. There was an official dedication in April and the mill was approaching full capacity throughout by yearend. This capacity (70,000 tons per year fiber) is felt to be inadequate, and plans for doubling it by 1975 are underway. Bolivia.—The 3-year United Nations Development Program (UNDP) to assist in establishing an asbestos industry a-t Cochabamba was terminated in 1972. UNDP called the project a success and thought the operation could function without further assistance. Canada.—The world's largest producer rebounded from last year's drop in production with a 3% increase in 1972. There were notds of caution from some industry leaders saying that market expansion would proceed at a slower rate and that new markets and applications were essential to a healthy industry. These probably well-founded views, however, were offset by the scurry of activity at producing mines and at those with potentials. This activity hints at a more optimistic viewpoint. Examples of this are— 1. The expansion a-nd modernization of the Canadian Johns-Manville Co., Ltd., mine and mill at Asbestos, Quebec, has not been curtailed. The project neared completion at yearend, and among the new facilities was the world's largest crusher. This 800-ton gyratory crusher can accept the -full load of a 200-ton dump truck at one time. 2. The Asbestos Corp's new mine on the Ungava Peninsula went into production and started shipping concentrate to Nordenheim, West Germany. Of real significance is the news that the tailings from
