IRRIGATION BY ICE.
A scheme for irrigation sby means of ice instead of water has, Bays the "Manchester Guardian,' been seriously put forward by an ingenious person in lexas. lie proposes to employ a rifle-like. mechanism to hre a series of ice-bullets into the soil. Each bullet is to be directed into the root-system of an individual plant or cluster of plants. The machine itself will be adjusted on a tractor containing a refrigerator that will keep it 'perpetually loaded with ice-slugs, something after the fashion of a machine-gun. When the ice-slug hds found lodgment near the root oi the plant it will presently melt and aiiswer the purpose intended. In ordinary, methods of irrigation the greater part of the' water finds lodgment at a distance from tho plant root, and either soaks into the earth or evapoiv ates into the air. The, new plan will prevent this waste, as the water will be {applied just where it is needed. The chief drawßack to its application will, it is suggested, be the high cost of manufacturing ice.,., .
