Do not read a book at table. Crumbs are apt to penetrate into the back-fold of the leaves.
Books are not intended for card-racks or for receptacles of botanical specimens.
Never leave a book open, face downward, under the pretext of keeping the place. If it remain long in that condition, it will probably ever afterwards jump open at that place.
Never pull books out of the shelves by the head-bands, or suffer them to stand long upon the fore-edge.
Books should not be toasted before a fire or be converted into cushions to sit upon.
Saturate a rag with camphor, and, when dry, occasionally wipe the dust from your books with it, and you will not be annoyed with book-worms.
Treat books gently; for "books are kind friends. We benefit by their advice, and they exact no confessions."
