No one has yet analyzed the effects upon the nervous system of the migrating worker, of the unsettlement of habits, and the change of surroundings and social environment, working in connection with the changed climatic conditions, and the often total change in food.

but I have got such an impression of selfishness in sitting down to read to myself, that this, added to unsettlement from company, etc., almost puts study out of sight.

This half conscious feeling of unsettlement on matters which in our explicit political arguments we treat as settled, is increased by the growing urgency of the problem of race.
