Modified Fischer retort assays resulted in up to 23.2 gallons of oil per ton of shale from carbonaceous shales from southern Iowa coal fields. Destructive distillation was also carried out in two different laboratory retorts. Yields of an oily liquid up to 39.9 gallons per ton were secured. Analyses showed one sample consisting of 89.4 per cent pentene-1 and 9.2 per cent 2-methyl butane with minor amounts of other compounds. Some combustible gas and a solid residue of possible value for road use were also obtained.
