I have now before me some leaves of a book, which, being waste, were used by our economical first printer, Caxton, to make boards, by pasting them together. Whether the old paste was an attraction, or whatever the reason may have been, the worm, when he got in there, did not, as usual, eat straight through everything into the middle of the book, but worked his way longitudinally, eating great furrows along the leaves without passing out of the binding; and so furrowed are these few leaves by long channels that it is difficult to raise one of them without its falling to pieces. This is bad enough, but we may be very thankful that in these temperate climes we have no such enemies as are found in very hot countries, where a whole library, books, bookshelves, table, chairs, and all, may be destroyed in one night by a countless army of ants. Our cousins in the United States, so fortunate in many things, seem very fortunate in this--their books are not attacked by the "worm"--at any rate, American writers say so. True it is that all their black-letter comes from Europe, and, having cost many dollars, is well looked after; but there they have thousands of seventeenth and eighteenth century books, in Roman type, printed in the States on genuine and wholesome paper, and the worm is not particular, at least in this country, about the type he eats through, if the paper is good. Probably, therefore, the custodians of their old libraries could tell a different tale, which makes it all the more amusing to find in the excellent "Encyclopaedia of Printing,"[1] edited and printed by Ringwalt, at Philadelphia, not only that the bookworm is a stranger there, for personally he is unknown to most of us, but that his slightest ravages are looked upon as both curious and rare. After quoting Dibdin, with the addition of a few flights of imagination of his own, Ringwalt states that this "paper-eating moth is supposed to have been introduced into England in hogsleather binding from Holland." He then ends with what, to anyone who has seen the ravages of the worm in hundreds of books, must be charming in its native simplicity. "There is now," he states, evidently quoting it as a great curiosity, "there is now, in a private library in Philadelphia, a book perforated by this insect." Oh! lucky Philadelphians! who can boast of possessing the oldest library in the States, but must ask leave of a private collector if they wish to see the one wormhole in the whole city!

The domestic black-beetle, or cockroach, is far too modern an introduction to our country to have done much harm, though he will sometimes nibble the binding of books, especially if they rest upon the floor.
