[To THE EDITOR Or THE " SPECTATOR.") SIE,—The correspondence under
this heading in your issue of February 11th seems to me to be conclusive upon the points in controversy. The authors of Neolithic Dew-ponds and Cattleways constructed a pond which collected hundreds of gallons of dew in a night when there was no rain. The trade (peripatetic) of dew-pond-maker was in full
swing about ten years ago. Inhabitants of Imber, in Wilts., were versed in the art of making them, and toured the country during the winter for that purpose. Apparently, however, the industry has come, or is coming, to an end, and the men formerly engaged in it are now past work. It seems to be a pity that this valuable source of water supply to the downs and other high places should be lost. I do not know what the cost of constructing one of these ponds would be. It may be prohibitive. Perhaps the owner of a suitable site would allow a small dew-pond to be constructed there, the work being done under the direction and supervision of the Imber veterans, and a careful note taken of the method, the expenses to be raised by subscription.—I am, Sir, &c., R. L.
