If there are several grades of aristocracy, the women of high rank are commonly exempt from industrial employment, or at least from the more vulgar kinds of manual labour.

The men of the upper classes are not only exempt, but by prescriptive custom they are debarred, from all industrial occupations.

The range of employments open to them is rigidly defined.

As on the higher plane already spoken of, these employments are government, warfare, religious observances, and sports.

These four lines of activity govern the scheme of life of the upper classes, and for the highest rank--the kings or chieftains--these are the only kinds of activity that custom or the common sense of the community will allow.
Indeed, where the scheme is well developed even sports are accounted doubtfully legitimate for the members of the highest rank.
