 If early rising be commenced in childhood it becomes a habit, and will then probably be continued through life. A boy ought on no account to be roused from his sleep; but as soon as he be awake in the morning, he should be encouraged to rise.

But if he rise early, he must go to bed betimes; it is a bad practice to keep him up until the family retire to rest. He ought, winter and summer, to seek his pillow by nine o'clock, and should rise as soon as he awakes in the morning.

This may in a measure be accounted for from the quantity of exercise the young take. Another reason may be, the young have neither pain nor care to keep them awake: while, on the contrary, the old have frequently one or both:

"Care keeps his watch on every old man's eye, And where care lodges, sleep will never lie."
