The foregoing figures are interesting from a chemical stand- 
point, but no doubt as experience is gained the results will be 
modified and improved. 
Ou shale in Cape Breton. 
Experiments have been made recently on the oil values of 
some shale deposits in Cape Breton County, which may appro- 
priately follow the notes on the distillation of Cape Breton coals, 
At Macadam’s Lake, on the North side of East Bay, the lower 
carboniferous measures rest on silurian and precambrian strata. 
Here a number of beds of black lustrous shale are found 
associated with conglomerates, gray shales, and sandstones 
pitching heavily to the south, away from the older rocks. 
These black shales are so highly charged with carbonaceous 
matter as to be capable of combustion. Explorations have 
shown a number of beds of this character from two to ten feet 
in thickness, extending for several miles in an easterly and 
westerly direction. 
The following results are stated to have been obtained from 
working tests. The distillation in retorts yields beside a little 
water, a quantity of heavy oil, a little gas, and coke available for 
fuel. The yield of oil is from 15 to 20 gallons per ton of 2000 Ibs. 
In refining this crude distillate, the products may be divided 
into different varieties, according to the market. A convenient 
division yields 20 per cent kerosene, 20 per cent white spindle 
or sewing machine oil, 40 per cent heavy lubricating oil, and 
20 per cent pitch.
