Billions of B a r r e l s o f Oil in S h a l e of N a v a l Oil Reserves in C o l o r a d o . A comprehensive study of the oil shale beds cropping out in Naval Oil Shale Reserves 1 and 3, Garfield County, Colorado, reveals a vast potential reserve of oil larger than hitherto believed present, Director W. E. W r a t h e r of the U. S. Geological Survey announced recently. The study, made by the Geological Survey in cooperation with the Department of the N a v y , Office of Petroleum and Oil Shale Reserves, shows the geology of an area northwest of Rifle, Colo., covering approximately 175 square miles, of which a b o u t 85 square miles is underlain by oil shales ranging from 700 to 1,200 feet thick, averaging 10 to 15 gallons oil yield per ton, and having a t o t a l potential yield of a b o u t 40 billion barrels of oil. A thinner rich unit within the same oil shale sequence ranges from 70 to 135 feet in thickness, yields a n average of 25 to 30 gallons of oil per ton, and has a t o t a l potential yield of a b o u t 10 billion barrels of oil. Approximately one-half of the shale oil resources considered in the report lies in the Naval Reserves. The area covered by the map is only a small part of the total area underlain by t h e oil shales of the Green River formation which is widespread in Colorado, Utah, and Wyoming. C h e m i c a l Polishing of Aluminum.--Aluminum tubing, pipe and round rod of machinable grades (61ST, 17ST, 24ST, 11ST, etc.) t h a t have been centerless ground with suitable grit (about No. 500) can now be made mirror bright, without mechanical polishing or buying. This is accomplished by Chemical-Polishing (non-electrolytic) by means of a dip for a few seconds into a specially formulated acid solution. Centerless-ground aluminum which has been treated thus (by ChemicalPolishing) is further enhanced as follows: (1) Its surfaces are passivated. (2) When subsequently anodized, the surfaces remain bright. (3) When subsequently anodized and colored (as with organic dyes) beautiful reflective colors are possible. No lacquers, waxes or after-buffing is required. (4) Striking resemblances to polished and buffed gold, silver, copper, brass, bronze, nickel, chromium, platinum, rhodium and other metals and alloys can be achieved. No lacquers, waxes or after buffing are required. (5) When subsequently chemically (non-electrolytic) oxidized, bright and protected natural aluminum surfaces result. No lacquers, waxes or after-buffing are required. Aluminum tubing, pipe and rod can be chemically-polished prior t o fabrication or machining, b u t it is preferable to perform this treatment after machining operations. Chemical-Polishing can be set u p in manufacturers and fabricators plants. Costs of chemical polishing are far less than mechanical polishing and buffing. Volume per hour is only limited b y the size of tanks. Investment versus a bank of polishing machines is much less, and the resultant p r o d u c t is better. In t h e meantime, manufacturers or fabricators who are interested may have their products processed in production in the Philadelphia plant (Technical Processes Division of Colonial Alloys Co.) or they may set up a pilot plant prior to their own production. T h e y are invited to submit specimens of their work, which will be chemically polished, or chemically polished and anodized or chemically polished, anodized and colored, in accordance with their specifications, a t no cost.
