But let us not forget that it is better for us, and better for the world, that we dream, and that we tread the thorny paths, and climb the weary steeps, and leave our bloody tracks behind in the pursuit of our dreams. For in their extravagant conceptions lie the germs of human government, and invention, and discovery; and from their mysterious vagaries spring the motive power of the world's progress. Our civilization is the evolution of dreams. The rude tribes of primeval men dwelt in caves until some unwashed savage dreamed that damp caverns and unholy smells were not in accord with the principles of hygiene. It dawned upon his _mighty_ intellect that one flat stone would lie on top of another, and that a little mud, aided by Sir Isaac Newton's law of gravitation, would hold them together, and that walls could be built in the form of a quadrangle. Here was the birth of architecture. And thus, from the magical dreams of this unmausoleumed barbarian was evolved the home, the best and sweetest evolution of man's civilisation. John Howard Payne touched the tenderest chord that vibrates in the great heart of all humankind when he gave to immortality his song of "Home, Sweet Home;" and thank God, the grand mansions and palaces of the rich do not hold all the happiness and nobility of this world. There are millions of humble cottages where virtue resides in the warmth and purity of vestal fires, and where contentment dwells like perpetual summer. The antediluvians plowed with a forked stick, with one prong for the beam and the other for the scratcher; and the plow boy and his sleepy ox had no choice of prongs to hitch to. It was all the same to Adam whether "Buck" was yoked to the beam or the scratcher. But some noble Cincinnatus dreamed of the burnished plowshare; genius wrought his dream into steel and now the polished Oliver Chill slices the earth like a hot knife plowing a field of Jersey butter, and the modern gang plow, bearing upon its wheels the gloved and umbrella'd leader of the Populist Party, plows up the whole face of the earth in a single day. What a wonderful workshop is the brain of man! Its noiseless machinery cuts, and carves, and moulds, in the imponderable material of ideas. It works its endless miracles through the brawny arm of labor, and the deft fingers of skill, and the world moves forward by its magic. Aladdin rubbed his lamp and the shadowy genii of fable performed impossible wonders. The dreamer of to-day rubs his fingers through his hair and the genii of his intellect work miracles which eclipse the most extravagant fantasies of the "Arabian Nights."
