IMPROVED DEW PONDS.

In many countries where rainfall is comparatively slight, there are frequent heavy dews, which are partly absorbed in the soil and partly lost by evaporation wnen the sun rises. A British man of science/ has suggested a means by winch the dew can tie collected in a reservoir. His plan is to arrange a radiating surlace over a tank or cistern and to interpose a heat insulator between the two. The cistern is sunk slightly into the ground on a somewhat eievaced site, and it is surmounted by heat insulating material. When water condenses on the radiating it drains into the reservoir, where it is protected from evaporation by the heat insulator. The inventor calculates that in the eastern countries of England, where the rainfall is often inadequate, a reservoir with a cover of 100 square yards and a storage capacity of 12,000 gallons would furnish an average daily supply of 120 gallons during the hot summer months and £0 gallons for the rest of thei year. r
