You may have excellent paste or cement, continually at hand, by buying at a druggist's an ounce of the best and cleanest gum tragacanth, with a little bit of corrosive sublimate not larger than a grain of corn, and dissolving them in a large half-pint of clear water, either warm or cold. Pick the gum tragacanth very clean, freeing it carefully from all dust and impurities. Put it with the corrosive sublimate into a white or queensware vessel having a close cover, and holding a pint, to allow for swelling. Pour on the water; cover it closely; and stir it with a stick, several times during the day. When sufficiently dissolved, the paste will be smooth throughout. The corrosive sublimate will cause it to keep good for a year or more; and it is an excellent and most convenient cement for all purposes, from wall-paper to artificial flowers. It must on no account be kept in a metal vessel or be stirred with a metal spoon, as it will then turn black. No house should be without this paste—and it should find a place in every library and office. When it is nearly used up, and becomes dry at the bottom, pour on a little water, and it will dissolve again.

Make no remarks with pen or pencil on the margin of any book that does not belong to yourself. Whatever may be your own opinion of certain passages, you have no right to disturb other readers by obtruding upon them these opinions, unasked for. The pleasure of reading a book from a public library, is frequently marred by finding, as you proceed, that some impertinent fools have been before you, and scribbled their silly comments all through; or indulged in sneers and vituperations directed at the author. You may lessen this annoyance by turning over all the leaves before you begin reading, and erasing all the marginal remarks with India rubber; and this will also be an act of kindness to the next reader after yourself. When written with ink, (as is often the case,) there is no remedy; and you must endure the infliction of being annoyed throughout the book by these gratuitous criticisms. In a book, even belonging to yourself, it is well to use the pencil sparingly; and only to correct an error of the press, or a chronological mistake of the author. All readers like to form their own opinions as they go along, without any prompting from those who have preceded them.

Never, on any consideration, allow yourself to lend a borrowed book. If requested to do so, it should be a sufficient excuse to say that "it is not your own." But if still urged, persist in declining steadily; for it is a liberty you have no right to take with any article belonging to another. Even if the owner is your sister, you should lend nothing of hers without first obtaining her permission. Whatever you borrow yourself, should pass safely from your hands to those of the owner. If a friend of yours is very desirous of reading a borrowed book, and has no other means of obtaining it, and you think you can depend on her carefulness and punctuality, (not else,) you may promise "to request for her the favour." And when the owner has consented, (and not till then,) you may transfer the book to the new borrower with strict injunctions to take great care of it, and to return it as soon as possible.

I have known a borrowed book travel round a whole circle of relations and acquaintances, till, when sent home at last, it was literally worn out by dint of use. And this when nearly the whole set were persons who could well afford to buy all they were desirous of reading. Many ladies like very well to read when they can do so at the cost of their friends; but they seem to regard the purchase of any thing to improve the mind, or amuse the fancy, as throwing away money which they would expend more to their satisfaction in articles of personal decoration. And is it not melancholy to see an intelligent child craving in vain for books, while bedizened with finery to gratify the vanity of an ostentatious mother?

If, with the permission of the owner, you have lent a borrowed book to a person who, having lost or injured it, still has the presumption to ask you to intercede for the loan of another, you are bound to refuse the request; and do so with civility but steadiness, assigning the true reason. It may be a salutary lesson to that borrower.

Remember never to send home any article in a wrapper of newspaper. Keep always in the house a supply of good wrapping-paper, bought for the purpose, and also of balls of twine. For putting up small things, what is called shoe-paper is very useful. It is both nice and cheap, selling from fifty to sixty cents per ream, according to the size, and there are twenty quires in a ream. There are varieties of stronger and larger wrapping-paper for articles that require such, and for parcels that are to be sent to far-off places, or to go by public conveyances. Such packages are best secured by red tape and sealing-wax. At every stationer's may be purchased all varieties of paper.

Be particularly careful of borrowed magazines, as the loss of one number spoils a whole set, and you may find great difficulty in replacing a lost number. Even a newspaper should be punctually returned. The owner may wish to file it, or to send it away to a friend. If lost or defaced while in your possession, send to the publishing-office and buy another. It is unsafe to leave the book you are reading in the parlour of a hotel. Always carry it away with you, whenever you quit the room—otherwise you will be likely to see it no more.

In America, books are so cheap (not to mention the numerous public libraries) that in most instances all who can afford it had better buy than borrow, particularly such works as are worth a second reading. If you find your books accumulating inconveniently, give away a portion of them to some lover of reading, who, less fortunate than yourself, is unable to expend much money with the booksellers.

I have often wondered to see a fair young stranger sitting day after day, idle and listless in the drawing-room of a hotel, when she might have known that there were bookstores in the immediate neighbourhood.

If, while in your possession, a borrowed book is irreparably injured, it is your duty to replace it by purchasing for the owner another copy. And, if that cannot be procured, all you can do is to buy a work of equal value, and to present that, as the only compensation in your power. Observe the same rule with all borrowed articles, lost or injured. The lender is surely not the person to suffer from the carelessness of the borrower. Leave no borrowed books in the way of children, and never give a young child a book to play with. Eat no cake or fruit over an open book, lest it be greased or stained. And take care not to blister or spoil the binding by putting it down in a wet place, for instance, on a slopped table.
