If the air of the bed-room be impure, the complexion, eyes and nerves must soon suffer. The hours of sleep are hours of recuperation. But that the building-up work may go on, pure air is indispensable. During the night the doors are not opened; there is no moving about; all is at a stand-still. Now the windows must be wide open. Unless there be a storm or the weather be intensely cold, the upper sash must come half way down, and the lower sash go half way up. If your ears are cold cover them, but give your lungs and blood pure oxygen, and plenty of it. If you would have beauty of skin and eyes, if you would enjoy a cheerful temper, and retain a youthful bloom, you must breathe a pure air all night, and all day, and always. No other law of health, no condition of beauty, is so imperative as this. When you go into the street, don't wear a veil and keep the air away from your lungs. Let it come in freely; it is your best friend. FLANNELS NEXT THE SKIN. Young ladies take pride in the fact that their skins are so delicate, they can't wear flannels. "Why, I couldn't live in flannels, my skin is so delicate." It is to be deeply regretted that this passion for delicacy and debility has taken such strong hold of young ladies. "Miss Fitznoodle, you must wear flannels next the skin, they will save you from colds, and keep up a fine, healthy circulation." "Oh, my! I couldn't wear flannels next my skin; it would set me crazy; my skin is so delicate!" "Miss Fitznoodle, you must rise early in the morning, take a bath, and go out for the fresh air." "Oh, my! I couldn't think of it; I should be sick in bed all day, I am so delicate!" "Miss Fitznoodle, you must sleep with your windows open." "Oh, my! I can't, I am so delicate!" I am always sorry to meet a young lady with weak, delicate morals; but rejoice to meet one with steady, fixed, determined morals. I am always sorry to meet a young lady with weak, delicate mind; but rejoice to meet one with clear, sharp, sturdy mind. And so I am sorry to meet a young lady with weak, delicate body; but rejoice to meet one with plump, elastic, sturdy body. If your skin be so sensitive that you can't wear flannels, use a pair of hair gloves morning and evening; put on strong flannels, be patient, and in two weeks you will have conquered your delicacy, and be able to enjoy what, in this climate, is an immense advantage in many ways. AMUSEMENTS FOR GIRLS. _Croquet_ is fashionable and useful, certainly better than nothing; but any game which can be played in a tight corset and long skirt cannot serve the muscles much; but it keeps the players out-doors, and so far is useful.
