Demosthenes was said, in his youth, to have stammered fearfully, and to have cured himself by his own prescription, namely, by putting a pebble in his mouth, and declaiming, frequently, slowly, quietly, and deliberately, on the sea-shore—the fishes alone being his audience,—until, at length, he cured himself, and charmed the world with his eloquence and with his elocution. He is held up, to this very day, as the personification and as the model of an orator. His patience, perseverance, and practice ought, by all who either are, or are interested in a stammerer, to be borne in mind and followed. 168. _Do you approve of a carpet in a nursery?_ No; unless it be a small piece for the child to roll upon. A carpet harbors dirt and dust, which dust is constantly floating about the atmosphere, and thus making it impure for him to breathe. The truth of this may easily be ascertained by entering a darkened room, where a ray of sunshine is struggling through a crevice in the shutters. If the floor of a nursery must be covered, let drugget be laid down; as this every morning may be taken up and shaken. The less furniture a nursery contains the better; for much furniture obstructs the free circulation of the air, and, moreover, prevents a child from taking proper exercise in the room. 169. _Supposing there is not a fire in the nursery grate, ought the chimney to be stopped to prevent a draught in the room?_ Certainly not. I consider the use of a chimney to be twofold: first, to carry off the smoke; and secondly (which is of quite as much importance), to ventilate the room, by carrying off the impure air, loaded as it is with carbonic acid gas, the refuse of respiration. The chimney, therefore, should never, either winter or summer, be allowed for one moment to be stopped. This is important advice, and requires the strict supervision of every mother, as servants will, if they have the chance, stop all chimneys that have no fires in the grates. EXERCISE. 170. _Do you approve, during the summer months, of sending a child out_ BEFORE _breakfast_? I do, when the weather will permit, and provided the wind be neither in an easterly nor in a northeasterly direction: indeed, _he can scarcely be too much in the open air_. He must not be allowed to stand about draughts or about entries, and the only way to prevent him doing so is for the mother herself to accompany the nurse. She will then kill two birds with one stone, as she will, by doing so, benefit her own as well as her child’s health. 171. _Ought a child to be early put on his feet to walk?_
