Page 11 - County has several croppings of copper ore in its northern half, which extend easterly into Siskiyou County. The copper belt also extends southward along the eastern side of the county and on into Humboldt County. As far as development in the past is concerned, the most prominent districts are Low Divide in the Smith River basin, and the Dr. Rock district in the southeastern portion of the county.

Development work has shown a mineralized zone 300 feet long, 10 to 40 feet wide and 125 feet deep, carrying kidneys and lenses of sulphide ore the size of a man's fist and larger. The largest kidney found was 75 feet long and six feet thick. The ore is a heavy iron sulphide carrying copper up to 8% or 9% and small values in gold and silver. During the year 1906, 400 tons of on; were shipped to the Peyton Chemical Company plant for treatment.
Page 27 - Two 50 hp boilers, one 14 hp engine, one 20 hp engine and one 40 hp engine complete the power equipment.

Page 47 - Analysis of Two Samples of Coal for Geo. R. Wells, Esq. The sulphur 's present in the form of sulphates of lime. By the combustion of two samples of coal of 1 pound each, the following quantities of water were evaporated: Sample 1. 13.86 pounds. Sample 2. 12.8 pounds. Both samples form a good soft coke. THOMAS PRICE & SON.
Page 47 - JL FLOOD, Esq., Dear Sir : I have made a careful technical analysis of a sample of coal received from you marked "Eel River Coal Mine, Mendocino County," and a sample marked "Wellington," with the following results : The cokes furnished by the two coals (sample of which I hand you with this report) are the same in appearance, but that of the Eel River coal contains 3.6 per cent of ashes, while that of the Wellington contains 8.4 per cent.

The Eel River coal weighs 81 pounds per cubic foot and in" place, 24.7 cubic feet will weigh a ton of 2000 pounds, but to store a ton, about 42 cubic feet will be required. As the sample of Eel River coal is, according to your statement, from the surface exposed...

The Eel River coal weighs 81 pounds per cubic foot and in" place, 24.7 cubic feet will weigh a ton of 2000 pounds, but to store a ton, about 42 cubic feet will be required. As the sample of Eel River coal is, according to your statement, from the surface exposed to extraneous moisture it is to be assumed that the coal at greater depth will contain much less moisture. If the Eel River and Wellington are both figured to dry coal, their carbon compares as follows...
