There is another great objection to having your nursery walls covered with _green_ paper-hangings; if any of the paper should become loose from the walls, a little child is very apt to play with it, and to put it, as he does everything else, to his mouth. This is not an imaginary state of things, as four children in one family have just lost their lives from sucking green paper-hangings. Green dresses, as they are colored with a preparation of arsenic, are equally as dangerous as green paper-hangings; a child ought, therefore, never to wear a _green_ dress. “It may be interesting to some of our readers,” says _Land and Water_, “to know that the new green, so fashionable for ladies’ dresses, is just as dangerous in its nature as the green wall-paper, about which so much was written some time since. It is prepared with a large quantity of arsenic; and we have been assured by several of the leading dressmakers that the work-women employed in making up dresses of this color are seriously affected with all the symptoms of arsenical poison. Let our lady friends take care.” Children’s toys are frequently painted of a green color with arsenic of copper, and are, consequently, highly dangerous to play with. The best toy for a child is a box of unpainted wooden bricks, which is a constant source of amusement to him. If you have your nursery walls hung with paintings and engravings, let them be of good quality. The horrid daubs and bad engravings that usually disfigure nursery walls, are enough to ruin the taste of a child, and to make him take a disgust to drawing, which would be a misfortune. A fine engraving and a good painting expand and elevate his mind. We all know that first impressions are the most vivid and the most lasting. A taste in early life for everything refined and beautiful purifies his mind, cultivates his intellect, keeps him from low company, and makes him grow up a gentleman! Lucifer matches, in case of sudden illness, should, both in the nursery and in the bed-room, always be in readiness; but they must be carefully placed out of the reach of children, as lucifer matches are a deadly poison. 164. _Have you any observation to make on the_ LIGHT _of the nursery_? Let the window, or, what is better, the windows, of a nursery be very large, so as to thoroughly light up every nook and corner of the room, as there is nothing more conducive to the health of a child than an abundance of light in the dwelling. A room cannot, then, be too light. The windows of a nursery are generally too small. A child requires as much light as a plant. Gardeners are well aware of the great importance of light in the construction of their greenhouses, and yet a child, who requires it as much, and is of much greater importance, is cooped up in dark rooms!
