338. _Have you any remarks to make on fresh air and exercise for boys and girls_? Girls and boys, especially the former, are too much confined within doors. It is imperatively necessary, if you wish them to be strong and healthy, that they should have plenty of fresh air and exercise; remember, I mean fresh air--country air, not the close air of a town. By exercise, I mean the free unrestrained use of their limbs. Girls, in this respect, are unfortunately worse off than boys, although they have similar muscles to develop, similar lungs that require fresh air, and similar nerves to be braced and strengthened. It is not considered lady-like to be natural--all then: movements must be measured by rule and compass! The reason why so many young girls of the present day are so sallow, under-sized, and ill-shaped, is for the want of air and exercise. After a time the want of air and exercise, by causing ill health, makes them slothful and indolent-it is a trouble for them to move from their chairs! Respiration, digestion, and a proper action of the bowels, imperatively demand fresh air and exercise. Ill health will inevitably ensue if boys and girls are cooped up a great part of the day in a close room. A distinguished writer of the present day says: "The children of the very poor are always out and about. In this respect they are an example to those careful mammas who keep their children, the whole day long, in their chairs, reading, writing, ciphering, drawing, practising music lessons, doing crotchet work, or anything, in fact, except running about in spite of the sunshine always peeping in and inviting them out of doors; and who, in the due course of time, are surprised to find their children growing up with incurable heart, head, lung, or stomach complaints." 339. _What is the lest exercise for a youth_?
