It is true that mechanics and manufacturers, as well as men of most other occupations, find fewer leisure hours than most farmers. The latter class of people are certainly more favorably situated than any other. But it is also true that even the former, almost without exception, can command a small portion of their time every day, for the purposes of mental improvement, if they are determined on it. Few individuals can be found in the community, who have not as much leisure as I had during the summer I have mentioned. The great point is to have the necessary disposition to improve it; and a second point, of no small importance, is to have at hand, proper means of instruction. Of the latter I shall speak presently.

The reason why laboring men make such rapid progress in knowledge, in proportion to the number of hours they devote to study, appears to me obvious. The mental appetite is keen, and they devour with a relish. What little they read and understand, is thought over, and perhaps conversed upon, during the long interval; and becomes truly the property of the reader. Whereas those who make study a business, never possess a healthy appetite for knowledge; they are always cloyed, nothing is well digested; and the result of their continued effort is either a superficial or a distorted view of a great many things, without a thorough or practical understanding of any.

I do not propose, in a work of this kind, to recommend to young men what particular books on any subject they ought to study. First, because it is a matter of less importance than many others, and I cannot find room to treat of every thing.

He who has the determination to make progress, will do so, either with or without books, though these are certainly useful. But an old piece of newspaper, or a straggling leaf from some book, or an inscription on a monument, or the monument itself—and works of nature as well as of art, will be books to him. Secondly, because there is such an extensive range for selection. But, thirdly, because it may often be left to the reader's own taste and discretion. He will probably soon discover whether he is deriving solid or permanent benefit from his studies, and govern himself accordingly. Or if he have a friend at hand, who will be likely to make a judicious selection, with a proper reference to his actual progress and wants, he would do wrong not to avail himself of that friend's opinion.

I will now mention a few of the particular studies to which he who would educate himself for usefulness should direct his attention.

1. GEOGRAPHY.

As it is presumed that every one whom I address reads newspapers more or less, I must be permitted to recommend that you read them with good maps of every quarter of the world before you, and a geography and correct gazetteer at hand. When a place is mentioned, observe its situation on the map, read an account of it in the gazetteer, and a more particular description in the geography. Or if you choose to go through with the article, and get some general notions of the subject, and afterwards go back and read it a second time, in the manner proposed, to this I have no objection.

Let me insist, strongly, on the importance of this method of reading. It may seem slow at first; but believe me, you will be richly repaid in the end. Even in the lyceum, where the subject seems to demand it, and the nature of the case will admit, it ought to be required of lecturers and disputants, to explain every thing in passing, either by reference to books themselves on the spot, or by maps, apparatus, diagrams, &c; with which, it is plain, that every lyceum ought to be furnished. The more intelligent would lose nothing, while the less so, would gain much, by this practice. The expense of these things, at the present time, is so trifling, that no person, or association of persons, whose object is scientific improvement, should, by any means, dispense with them.

No science expands the mind of a young man more, at the same time that it secures his cheerful attention, than geography—I mean if pursued in the foregoing manner. Its use is so obvious that the most stupid cannot fail to see it. Much is said, I know, of differences of taste on this, as well as every other subject; but I can hardly believe that any young person can be entirely without taste for geographical knowledge. It is next to actual travels; and who does not delight in seeing new places and new objects?

2. HISTORY.
