"My reply to that suggestion could be made at once by simply testing the experiment on a small scale, or a large one, either. But I prefer at present to refute your proposition by an argument drawn from nature herself. If you correctly remember, the first time I had the pleasure of seeing you was on the island of Galveston, many years ago. Do you remember relating to me at that time an incident concerning the effects of a prairie on fire, that you had yourself witnessed but a few days previously, near the town of Matagorde? If I recollect correctly, you stated that on your return journey from that place, you passed on the way the charred remains of two wagon-loads of cotton, and three human beings, that the night before had perished in the flames; that three slaves, the property of a Mr. Horton, had started a few days before to carry to market a shipment of cotton; that a norther overtook them on a treeless prairie, and a few minutes afterward they were surprised by beholding a line of rushing fire, surging, roaring and advancing like the resistless billows of an ocean swept by a gale; that there was no time for escape, and they perished terribly in fighting the devouring element?" "Yes; I recollect the event." "Now, then, I wish a reply to the simple question: Did the single spark, that kindled the conflagration, consume the negroes and their charge? No? But what did? You reply, of course, that the spark set the entire prairie on fire; that each spear of grass added fuel to the flame, and kindled by degrees a conflagration that continued to burn so long as it could feed on fresh material. The pilule in that vial is the little spark, the oceans are the prairies, and the oxygen the fuel upon which the fire is to feed until the globe perishes in inextinguishable flames. The elementary substances in that small vial recreate themselves; they are self-generating, and when once fairly under way must necessarily sweep onward, until the waters in all the seas are exhausted. There is, however, one great difference between the burning of a prairie and the combustion of an ocean: the fire in the first spreads slowly, for the fuel is difficult to ignite; in the last, it flies with the rapidity of the wind, for the substance consumed is oxygen, the most inflammable agent in nature." Rising from my seat, I went to the washstand in the corner of the apartment, and drawing a bowl half full of Spring Valley water, I turned to Summerfield, and remarked, "Words are empty, theories are ideal--but facts are things."
