โœฆ Synopsis

methods similar to those used in coal mining will be used. In the eastern states where the black oil shales of a cannel-coal nature overlie coal seams near the surface, and elsewhere where conditions permit, stripping or quarrying methods may be feasible.

The dust produced in Scottish shale-mining operations, according to some investigators, is non-inflammable and non-explosive. However, this must not be taken to indicate that oil shale of similar characteristics will be encountered in American shale mines. The results of the present tests show that oil-shale dust may present a source of danger in American mines, particularly when comparatively rich material is being worked. Further details are shown in Serial 2758 of the Bureau of Mines.

## Abstract The toxic or harmful effects resulting from the use of flue dust containing different amounts of cyanides and thiocyanates as a potassic fertilizer for a variety of different crops have been studied. Tomato plants have been found to be particularly susceptible to flue dusts containing c
