Our ancestors had a difficulty in procuring them. Our difficulty now is what to select. We must be careful what we read, and not, like the sailors of Ulysses, take bags of wind for sacks of treasure--not only lest we should even now fall into the error of the Greeks, and suppose that language and definitions can be instruments of investigation as well as of thought, but lest, as too often happens, we should waste time over trash. There are many books to which one may apply, in the sarcastic sense, the ambiguous remark said to have been made to an unfortunate author, "I will lose no time in reading your book." There are, indeed, books and books, and there are books which, as Lamb said, are not books at all. It is wonderful how much innocent happiness we thoughtlessly throw away. An Eastern proverb says that calamities sent by heaven may be avoided, but from those we bring on ourselves there is no escape. Many, I believe, are deterred from attempting what are called stiff books for fear they should not understand them; but there are few who need complain of the narrowness of their minds, if only they would do their best with them. In reading, however, it is most important to select subjects in which one is interested. I remember years ago consulting Mr. Darwin as to the selection of a course of study. He asked me what interested me most, and advised me to choose that subject. This, indeed, applies to the work of life generally. I am sometimes disposed to think that the readers of the next generation will be, not our lawyers and doctors, shopkeepers and manufacturers, but the laborers and mechanics. Does not this seem natural? The former work mainly with their head; when their daily duties are over the brain is often exhausted, and of their leisure time much must be devoted to air and exercise. The laborer and mechanic, on the contrary, besides working often for much shorter hours, have in their work-time taken sufficient bodily exercise, and could therefore give any leisure they might have to reading and study. They have not done so as yet, it is true; but this has been for obvious reasons. Now, however, in the first place, they receive an excellent education in elementary schools, and in the second have more easy access to the best books. Ruskin has observed that he does not wonder at what men suffer, but he often wonders at what they lose. We suffer much, no doubt, from the faults of others, but we lose much more by our own ignorance.
