COTTON LINING FOR WATER CHANNELS

USE OF TAR-IMPREGNATED

FABRIC

EXPERIMENTS BEING MADE IN U.S.A.

Engineers are experimenting with an asphalt-impregnated cotton fabric as a lining material to prevent water seepage from a large water reservoir in the United States. If the first experiment is successful, "the possibility of using more impregnated cotton for large public swimming pools, earth dams, levee fills and flood control work suggests itself," the Christian Science Monitor notes.

will apply the cotton fabric lining over more than halt' uie totai area of the new 300,000,000 gallon Baldwin Hills Reservoir of fV >° Los Angeles of Water and Power in the State of California. It is estimated that they will use about 500,000 square feet of the cotton fabric.

The irrigation canal and "laterals'' - -'vh' rt, i carrv the reservoir's water from the main course into the small(.i uncnes on the surrounding farm acreage—also are to be lined with the fabric. Water conservation and cotton industry experts are watching the new project with interest. They expect to find out what effects weather, friction, weed growth, and soil chemicals will have on the new fabric.

The experiment is in line with others designed to improve the use ff water which the Christian Science Monitor points out, is "becoming a matter of major concern m trie western sections of the United States as well as in many other countries of the world."
