DEWDROPS.

♦ All dewdrops are perlecjiy round. Dew is deposited only on a fine, clear night.

livening dew is unhealthy, being laden with noxious exhalations. More clew is deposited on cultivated than on uncultivated land. Dew will not stay on rose leaves, because iliese have an essential oil in them. Dew rolls off cabbage and life leaves, because they are coated with a fine waxen powder. , Dew is most abundant in exposed situation, there being less to arrest the radiation of the earth’s heat. There is no dew after a windy night; it is evaporated as fast as it forms. We get most dew alter a hot summer’s day and a wasterly wind Little or no dew is ever deposited on smooth stones, polished metal, or woollen material. If there were no sunsets there would be no dew, and vegetation would perish, it is the sun’s withdrawal, and the cooling of the earth, plants, etc., by radiation of the heat, that makes them cold enough to condense the air vapour into dew. Nature’s wisdom is shown by the fact that plants with woolly leaves require most moisture, and it is those leaves which radiate most heat and therefore get most dew.
