will not again curse the earth any more for man's sake. While the earth remaineth, seed-time and harvest, cold and heat, summer and winter, day and night shall not cease." And next, the fact is not so; for if you root up the thorns and thistles, and keep your land clean, then assuredly you will grow fruit-trees and not thorns, wheat and not thistles, according to those laws of Nature which are the voice of God expressed in facts. And yet the words are true. There is a curse upon the earth, though not one which, by altering the laws of nature, has made natural facts untrustworthy. There is a curse on the earth; such a curse as is expressed, I believe, in the old Hebrew text, where the word "adamah" (correctly translated in our version "the ground") signifies, as I am told, not this planet; but simply the soil from whence we get our food; such a curse as certainly is expressed by the Septuagint and the Vulgate versions: "Cursed is the earth"-- [Greek]; "in opere tuo," as the Vulgate has it--"in thy works." Man's work is too often the curse of the very planet which he misuses. None should know that better than the botanist, who sees whole regions desolate, and given up to sterility and literal thorns and thistles, on account of man's sin and folly, ignorance and greedy waste. Well said that veteran botanist, the venerable Elias Fries, of Lund: "A broad band of waste land follows gradually in the steps of cultivation. If it expands, its centre and its cradle dies, and on the outer borders only do we find green shoots. But it is not impossible, only difficult, for man, without renouncing the advantage of culture itself, one day to make reparation for the injury which he has inflicted: he is appointed lord of creation. True it is that thorns and thistles, ill-favoured and poisonous plants, well named by botanists rubbish plants, mark the track which man has proudly traversed through the earth. Before him lay original Nature in her wild but sublime beauty. Behind him he leaves the desert, a deformed and ruined land; for childish desire of destruction, or thoughtless squandering of vegetable treasures, has destroyed the character of nature; and, terrified, man himself flies from the arena of his actions, leaving the impoverished earth to barbarous races or to animals, so long as yet another spot in virgin beauty smiles before him. Here again, in selfish pursuit of profit, and consciously or unconsciously following the abominable principle of the great moral vileness which one man has expressed-- 'Apres nous le Deluge'--he begins anew the work of destruction. Thus did cultivation, driven out, leave the East, and perhaps the deserts formerly robbed of their coverings; like the wild hordes of old over beautiful Greece, thus rolls this conquest with fearful rapidity from East to West through America; and the planter now often leaves the already exhausted land, and the eastern climate,
