This moill itate of the atmofphere exiits throughout the whole year; but is greater in proportion to the quantity and denfity of the clouds. In the rainy feafon torrents of water rulh down the craggy fides of the higher regions of thefe mountains; and the rivulets, often overflow- ing their banks by this addition, inundate the country below. In the dry feafon, a con- siderable degree of moifture is always percep- tible ; but then it falls during the night in the form of dew; and the llreams and rivu- lets, though plentifully fupplied, run in their natural channels with a placid current, ex- cept where their courfe is interrupted by precipitous rocks or large Hones.
