Most of the early coal production in Tennessee was for iron-making, and here, contrary to the usual custom, coal was used in the early furnaces before charcoal was. There was no salt industry of any volume. A considerable quantity of the coal used in the state before the Civil War was brought down the Cumberland River from eastern Kentucky, and both Pittsburgh coal and coal from the river mines in Kentucky was brought up the Tennessee River. The Memphis market was supplied almost entirely by river from Pittsburgh seam mines until the end of the period. The available data did not permit the production by counties to be estimated. [ ]

The experiences of Canex Placer Ltd. in establishing vegetation on a lead-zinc tailing pond are presented, hoping others with similar challenges will be benefited. History The tailing ponds are the result of 23 years of mining and milling operations, which ceased in August 1970. Roughly 7.9 million tons of lead-zinc ore were removed in that time. The ponds are located between Salmo River and B.C. Highway 3, about 8 miles north of Nelway near the Canada-U.S. border.

Officials of the State Department have expressed their hope that a considerable number of technical men will take the examination for consular service. The Department recognizes that the interest of the United States will be served best if technical men are made available through these examinations for vacancies at points where their training will be of special value. Industrial engineers who have passed the con-sular examination will be assigned to industrial centers of Europe or South America. Mining engineers, chemists, electrical engineers, etc., will be assigned to industrial centers requiring special training.

AFTER the aforementioned subjects, I wish to speak to you of the method of welding bells that are cracked. This seems to me an ingenious thing, little used, but of great usefulness. Bells are cracked by the blows of too large a clapper or by excessive and forced ringing. This often cracks them at the rim, in the heart, or in some other place so that they lose their tone because of these cracks, and give no more

It was customary formerly to publish an index of the Transactions about every fifth volume, but since the Institute began in 1913 to publish three volumes instead of one volume per year, this has been deemed impracticable and unnecessary. No collective index has been published since the one covering Volumes I to XXXV inclusive, excepting a short one covering Volumes XXXVI to XL inclusive. The Board of Directors, therefore, upon the recommendation of the Committee on Papers and Publications, decided to publish this index of Volumes XXXVI to LV inclusive, and thus enable members to have in condensed space the collective indexes of all the volumes of the Transactions.

CYCLONE thickeners are "hydraulic centrifuges" designed either to produce a maximum practical separation between the water and solids of a feed slurry or to classify the slurry solids according to particle settling rate. The possibilities of utilizing the thickener to "close" plant water circuits have been investigated.
