The prospect at present is not bright; year by year Americans grow thinner, lighter, and shorter-lived. Ælian‘s Americans, we may remember, though they were greatly superior to the Greeks in stature, were inferior to them in length of life. The women show even greater signs of weakness than the men, and the high, undulating tones which are affectation in the French, are natural to the ladies of America; little can be expected of women whose only exercise is excessive dancing in overheated rooms. The American summer, often tropical in its heat, has much to answer for, but it is the winter which makes the saddest havoc among the younger people, and the boys and girls at school. Cooped up all day in the close air of the heated school-house, the poor children are at night made to run straight back to the furnace-dried atmosphere of home. The thermometer is commonly raised indoors to eighty or ninety degrees Fahr. The child is not only baked into paleness and sweated bit by bit to its death, but fed meantime, out of mistaken kindness, upon the most indigestible of dainties--pastry, hot dough-nuts, and sweetmeats taking the place of bread, and milk, and meat--and is not allowed to take the slightest exercise, except its daily run to school-house. Who can wonder that spinal diseases should prevail? One reason why Americans are pale and agueish is that, as a people, they are hewers of primeval forest and tillers of virgin soil. These are the unhealthiest employments in the world; the sun darts down upon the hitherto unreached mould, and sets free malarious gases, against which the new settlers have no antidotes.
