A kindred improvement is about to be inaugurated in the more extended and diversified employment of Gas. A hundred models of Gas Stoves, Gas Burners, Gas Cooking Ranges, etc., were exhibited at the Fair, each warranted, (as usual,) to save half the fuel and render treble the service of any other; yet I was not able to designate any one of them as particularly meritorious, nor did the Jury on this department award a premium to any. All seems yet crude and infantile in this field of invention. Yet the study of the various models and contrivances for Gas-burning there presented, fixed me in the novel faith that Gas is ultimately to be not only the main agent of illumination but the chief fuel also of all cities and villages; that the time is at hand when the head of a family, the solitary lodger, requiring either heat or light, will simply touch a bell in his own room and be supplied with the indicated quantity of Gas, whether for culinary purposes, for warmth, for light, or altogether; and that thus the cost, the trouble, the dust, of making fires in all parts of a building, carrying fuel thither and removing ashes therefrom, will be obviated; and a single fire, constantly maintained, subserve admirably the purpose of them all, saving the labor and cost of five hundred wasteful kindlings and clearings, beside affording heat at the moment it is wanted, and stopping its consumption the instant the want is satisfied. This is but one among a thousand noiseless agencies constantly preaching the advantages and economies of Combination, and indicating the certainty that through Coöperation lies the way whereby Labor is to emerge from bondage, anxiety and need into liberty and assured competence. This truth, long apparent to the eye of Reason, threatens to be made palpable even to stolidity and stagnation by the sharp spur of Necessity. Rude, rugged Labor must organize itself for its appointed task of production, or it will soon have nothing to do. It must concentrate its energies for the creation of commodious and economical homes, or it will have no home but the Union Work-house. It must save and combine its earnings, for the purchase and command of Machinery; or Machinery, owned by and working for Capital alone, will reduce it to insignificance, want, and despair.
