 does not rain, the windows must be thrown wide open, and, directly after he has risen from bed, the clothes ought to be thrown entirely back, in order that they may become, before the bed be made, well ventilated and purified by the air:

"Do you wish to be healthy?— Then keep the house sweet; As soon as you're up  Shake each blanket and sheet.

Leave the beds to get fresh On the close-crowded floor; Let the wind sweep right through— Open window and door.

The bad air will rush out As the good air comes in, Just as goodness is stronger And better than sin.

Do this, it's soon done, In the fresh morning air,— It will lighten your labor And lessen your care.

You are weary—no wonder; There's weight and there's gloom Hanging heavily round In each overfull room.

Be sure all the trouble Is profit and gain, For there's headache, and heartache, And fever, and pain,

Hovering round, settling down In the closeness and heat: Let the wind sweep right through Till the air's fresh and sweet.
