"That's my doctrine exactly," he said.

Then I asked,--

"Why don't you always drive two miles an hour?"

"But my patients would all die," replied my friend.

I did not say aloud what was passing in my mind,--that the danger to his patients might be less than he imagined; but I suggested, that most men, as well as most horses, had duties in this life which involved the necessity of rapid and vigorous motions,--and that, were this slow movement generally adopted, every phase of human life would be stripped of progress, success, and glory.

As our artificial training is designed to fit us for the more successful performance of the duties of life, I suggest that the training should be, in character, somewhat assimilated to those duties. If you would train a horse for the carriage, you would not prepare him for this work by driving at a slow pace before a heavy load. If you did, the first fast drive would go hard with him. Just so with a man. If he is to lift hogsheads of sugar, or kegs of nails, as a business, he may be trained by heavy-lifting; but if his business requires the average activity and free motions of human occupations, then, upon the basis of his heavy, slow training, he will find himself in actual life in the condition of the dray-horse who is pushed before the light carriage at a high speed.

Perhaps it is not improper to add that all this talk about expenditure of vitality is full of sophistry. Lecturers and writers speak of our stock of vitality as if it were a vault of gold, upon which you cannot draw without lessening the quantity. Whereas, it is rather like the mind or heart, enlarging by action, gaining by expenditure.

When Daniel Boone was living alone in Kentucky, his intellectual exercises were doubtless of the quiet, slow, heavy character. Other white men joined him. Under the social stimulus, his thinking became more sprightly. Suppose that in time he had come to write vigorously, and to speak in the most eloquent, brilliant manner, does any one imagine that he would have lost in mental vigor by the process? Would not the brain, which had only slow exercise in his isolated life, become bold, brilliant, and dashing, by bold, brilliant, and dashing efforts?

A farm-boy has slow, heavy muscles. He has been accustomed to heavy exercises. He is transferred to the circus, and performs, after a few years' training, a hundred beautiful, splendid feats. He at length reaches the matchless Zampillacrostation of William Hanlon. Does any one think that his body has lost power in this brilliant education?

Is it true, either in intellectual or physical training, that great exertions, under proper conditions and limitations, exhaust the powers of life? On the contrary, is it not true that we find in vigorous, bold, dashing, brilliant efforts the only source of vigorous, bold, dashing, and brilliant powers?
