Show Druii.i.-e. How few people realize tbe results of extensivo drainage, such as a highly civilized civ-ilized country presents. No inconsiderable inconsider-able changes ara wrought by artificial drainage. Much of surface water, instead in-stead of being left to forui marshes, saturate sat-urate tlio soil or bo taken up by evaporation, evapora-tion, is carried away underground through drain pipes. Consequently the air is not so moist us formerly, and the soil, instead of being constantly chilled by evaporation, is rendered warm and genial. This result has been particularly particu-larly noticed .in England and Scotland, where very extensive areas have been artificially dr.iined. Holland has been, one might say, re-cbiimed re-cbiimed from tho sea. Tho water has been dyked out, and many parts of the country th.it were tho bottom of the sea s are now dry land, and though below sea ! level form the homes of happy and industrious in-dustrious communities. Years ago there ; were along the lower banks of the Mis-eisiippi Mis-eisiippi "drmvued bids," subject to over flow aud uninhabitable, covering an area larger than the fne of New York. Alany of these lands have been reclaimed by means of levees. Thus, by man's ingenuity, in-genuity, are the surface, climate and general physical condition of the earth I being changed.
