There is an ongoing need for the abstracting and coding of new information in the energy and environmental studies field for addition to the BIRS system. There are approximately 3000 bibliographic entries coded into the BIRS system. The bibliographic retrieval system was designed to be run by the general data management System 2000. The information system with entries of coal research, land reclamation and other energy and environmental studies is up and on line. As more entries are coded they are loaded into the system.

AMONG the many interesting objects to be seen at the Vienna Exhibition last summer, the model of the system of underground transportation by a continually moving chain, adopted at the Hasard collieries, at Micheroux, near Liége, Belgium, was one of the most attractive, and full of valuable suggestion to mining engineers. These collieries are under the superintendence of the celebrated

MILNOR ROBERTS,* Seattle, Wash. (written discussion?).-The coal fields of Washington, on which Mr. F. A. Hill's paper gives much detailed information, lie on the western slope of the Cascade Range, which extends north and south through the State just west of its center. The mines are on the lower half of the slope, the lignite fields of Lewis and Thurston Counties extending into valleys and low hills west of the mountains. An exception is to be noted in the case of the Roslyn field, a small but important area which lies on the eastern slope.

The use of economic models for forecasting purposes is an inexact yet necessary tool for mineral decision making. One method not commonly used is cyclical analysis because of its "non-scientific approach". However, under certain circumstances a modified cyclical approach can provide useful insight to mining companies. The current paper discusses mineral modeling, the type of economic models and the use of cyclical forecasting for mining firms (not speculators) involved in precious metals.
