This fact does not, however, preclude another, that the environment has helped in the process.

Change of scene is beneficial to others besides invalids.
How stimulating to growth a different habitat can prove, when at all favorable, is perhaps sufficiently shown in the case of the marguerite, which, as an emigrant called white-weed, has usurped our fields.

The same has been no less true of peoples.

Now these Far Eastern peoples, in comparison with our own forefathers, have travelled very little.

A race in its travels gains two things: first it acquires directly a great deal from both places and peoples that it meets, and secondly it is constantly put to its own resources in its struggle for existence, and becomes more personal as the outcome of such strife.
