In accounting for his classmates in the various walks of life, he reported that more than one third of them were settled to the occupation of Pullman porters.
The largest number of Negroes who have gone North during this period, however, belong to the intelligent laboring class.

Some of them have become discontented for the very same reasons that the higher classes have tired of oppression in the South, but the larger number of them have gone North to improve their economic condition.

Most of these have migrated to the large cities in the East and Northwest, such as Philadelphia, New York, Indianapolis, Pittsburgh, Cleveland, Columbus, Detroit and Chicago.
To understand this problem in its urban aspects the accompanying diagram showing the increase in the Negro population of northern cities during the first decade of this century will be helpful.
Some of these Negroes have migrated after careful consideration; others have just happened to go north as wanderers; and a still larger number on the many excursions to the cities conducted by railroads during the summer months.

Sometimes one excursion brings to Chicago two or three thousand Negroes, two thirds of whom never go back.

They do not often follow the higher pursuits of labor in the North but they earn more money than they have been accustomed to earn in the South.
