"You don't know what it is. It is one of the most practical and useful volumes there is. It is not so taking a book for rapid reading as many others; but it is a work to be studied."

"What is the particular use of it?"

"Its use to me is, the information it gives concerning those objects and illustrations that have the most power over the hearts of men in speaking and writing. I should think it must aid a person very much in the ability to illustrate and enforce a subject."

"I suppose you are right," said Charlie, "but it is all gammon to me. That is what helped you to illustrate and enforce the claims of our Dramatic Society in the lyceum, was it?" meaning no more than a joke by this suggestion.

"No; I never read it much until recently," answered Nat.

"Well, I thought you had some of the sublime in that speech, if you had none of the beautiful," continued Charlie in a vein of humor. "I concluded that Burke might have helped you some, as I thought it hardly probable that Nat did it alone."

"What do you think you should do, Charlie, if you had not me to make fun of?" asked Nat. "You would have the dyspepsia right away. It is altogether probable that I was made to promote your digestion."

"Very likely," replied Charlie, assuming a grave appearance. "I believe they administer rather powerful medicine for that disease. But they say you go to college now," and here his seeming gravity was displaced by a smile. "When are you going to graduate?"

"About the time you know enough to enter," answered Nat, paying back in the same coin.

Charlie was much amused at this turn, for his allusion to college was in a jesting way, occasioned by the fact that Nat had obtained permission to use the library of Cambridge College, to which place he frequently walked to consult volumes. It was a great advantage to him, to enjoy the opportunity to examine works which he could not possess on account of his poverty, and such works, too, as the library of his native village did not contain. It was quite a walk to Harvard College, but necessity made it comparatively short and pleasant to Nat. Many times he performed the trip to settle some point of inquiry, or compass some difficult subject; and the journeys proved to him what similar walks did to Count Rumford many years before. He, also, was accustomed to visit the Athenæum in Boston, at this period of his life, where he spent some pleasant and profitable hours. To many youth it would seem too great an outlay of labor to make for an education; but to Nat it was a cheap way of obtaining knowledge. He was willing to make any sacrifice, and to perform almost any labor, if he could add thereby to his mental stature. Often a volume would completely absorb his thoughts upon a given subject, and he could not let it alone until he had thoroughly canvassed it; and this was one of the elements of his success—a power of application, in which all the thoughts were concentrated on the subject before him. It was thus with Hugh Miller from his boyhood. As an instance, his biographer relates, that, on one occasion he read a work on military tactics—a subject that one would think could scarcely command his attention—and he was so thoroughly controlled by the desire to understand the military movements described, that he repaired to the sea-shore, where he got up an imposing battle between the English and French, with a peck or half bushel of shells, one color representing one nation, and another color the other nation. Time after time he fought an imaginary battle with shells, until he definitely understood the military tactics described in the volume which he read.
