Hydraulic hose

Definition of hydraulic hose

• A common hose used in gold-washing for conveying water to alluvial claims, where by the fall and pressure of the water the detritus is broken down and washed.
• The canvas hose used in California and other countries for hydraulic mining, is usually covered with iron rings or close cord netting, and the pressure such a structure bears is very considerable. With a large volume of water, vast quantities of detritus and gravel can be removed with little manual labor. A pressure from 60 lbs to 100 lbs to the square inch is common. Only where the fall is considerable, and water abundant, can hydraulic mining be profitably pursued.
