Reading Anthracite, like AIME, is celebrating its 100th anniversary. While Reading marks a century in the mining, preparation and marketing of domestic anthracite, AIME commemorates 100 years of parallel endeavor in promoting the economical production of minerals and metals and the welfare of those employed in the industries dedicated to this pursuit. Both Reading and AIME possess another common denominator, in that both were conceived in the eastern anthracite fields of Pennsylvania, where coal reigned supreme in the early days of mining.

CONTRARY to the natural order of art, it has been discovered how to cast in moist earth in order to avoid labor and expense. This is truly a thing that many desire and few practice because it is not as smooth a way nor as easy to effect as it apparently seems. To do this, one part of fine-grained yellow tuff is taken, or some very

A sampling technique has been developed for procuring a sample of sinter representative of the entire depth of the sintering bed. The sampling method involves the use of an open-bottom metal basket that rides on the grate of the sintering machine and when removed contains a sample of the sintered product. Additional data have been obtained to indicate that the tumbler test is a suitable means of measuring sinter strength.
