"Second, the changing water carried away the heat as fast as it was produced. While it is true that a cannon ball becomes heated in its motion through the air, its surface is cooled when it strikes a body of water, notwithstanding that its great velocity is altogether overcome by the water. The friction between the water and the iron does not result in heated iron, but the contrary. The water above the rapids of a river has practically the temperature of the water below the rapids, regardless of the friction that ensues between these points. Admit, however, that heat is liberated as the result of the friction of solids with water, and still it does not follow that this heat will perceptibly affect the solid. With a boat each particle of water carries the heat away, each succeeding portion of water takes up the heat liberated by that preceding it. Thus the great body of water, over which our boat sped, in obedience to the ordinary law, became slightly warmed, but its effect upon the boat was scarcely perceptible. Your comparison of the motion of a meteor, with that of our boat, was unhappy. We moved rapidly, it is true, in comparison with the motion of vessels such as you know, but comparison can not be easily drawn between the velocity of a boat and that of a meteor. While we moved at the rate of many miles a minute, a meteor moves many times faster, perhaps as many miles in a second. Then you must remember that the force of gravitation was so slight in our position that--" "Enough," I interrupted. "We will pass the subject. It seems that you draw upon science for knowledge to support your arguments, however irrational they may be, and then you sneer at this same method of argument when I employ it." He replied to my peevish complaint with the utmost respect by calling to my attention the fact that my own forced argument had led to the answer, and that he had simply replied to my attacks. Said he: "If I am wrong in my philosophy, based on your science thought, I am right in my facts, and science thought is thus in the wrong, for facts overbalance theory. I ask you only to give me the attention that my statements merit. I am sincere, and aim to serve your interests. Should investigation lead you hereafter to infer that I am in error, at our final interview you can have my considerate attention. Be more charitable, please." Then he added: "Is there any other subject you wish to argue?" "Yes," I answered, and again my combativeness arose; "yes. One of the truly edifying features of your narrative is that of the intelligent guide," and I emphasized the word intelligent, and curled up my lip in a sarcastic manner. "Proceed."
