Abstract
SOME observations made last autumn in Cornwall may throw light on the fall of dust in South Wales. On September 2, during gusty weather with squalls from the E.N.E., I watched from my window at Carbis Bay (270 feet above the sea) puffs and swirls of dust rising from the desert-like flat at the mouth of the Red River. The dust-cloud rose above the top of Godrevy Towans (230 feet), nearly blotted out Godrevy Lighthouse and then spread in a well-defined belt across St. Ives Bay for more than three miles to near St. Ives Head, which it must have passed, though this part of the track was invisible from my point of view. A fortnight earlier a similar observation had been made under identical conditions by Mrs. Reid. On neither occasion did the wind reach the force of a gale, it was merely a strong, dry east wind.
