These local or sublocal winds are cliaracteristic. Judg-ing from observations covering several weeks, the valley is wind-sweptlongitudinally for an average of eighteen or twenty hours daily, thewinds ranging fiom strong breezes to gales so stiff as to load the airwith sand ashore and spray asea; and even the calms may be broken.
