Early in the summer of 1916, the Pennsylvania and Erie Railroads promiscuously picked up trainloads of negroes from Jacksonville, St. Augustine and Pensacola, Florida. They were at first grouped in camps. The promise of a long free ride to the North met with instant favor, and wild excitement ensued as the news circulated. Carloads of negroes began to pour into Pennsylvania. When they had once touched northern soil and discovered that still higher wages were being offered by other concerns, many deserted the companies responsible for their presence in the North. Some drifted to the steel works of the same State; others left for points nearby. Letters written home brought news of still more enticing fields, and succeeded in stimulating the movement. Of the 12,000 negroes brought into Pennsylvania by the Pennsylvania Railroad, less than 2,000 remained with the company.[58] It will no doubt be interesting to know exactly where these negroes settled in the North. For the purpose of understanding this distribution the North may well be divided according to the two main lines followed by the migrants in leaving the South. The South and middle Atlantic States sent the majority of their migrants directly up the Atlantic coast while the south central States fed the Northwest. There is, of course, no hard line of separation for these two streams. Laborers were sought in fields most accessible to the centers of industry, but individual choice as displayed in the extent of voluntary migration carried them everywhere. The New England States, which were probably the first to attract this labor, were Connecticut and Massachusetts. The tobacco fields of Connecticut with Hartford as a center received the first negro laborers as mentioned above. Before a year had passed there were over 3,000 southern negroes in the city of Hartford. Massachusetts had its new war plants which served as an attraction. Holyoke received considerable advertisement through the National League on Urban Conditions among Negroes, and as a result secured a number directly from the South. Boston, which has always stood as a symbol of hope for those who sought relief from southern conditions, has not, however, at any time afforded any great variety of occupations for the peasant class of negroes. The receptions staged by the negro leaders of that city were stimulated apparently more by the sentimental causes of the movement than any other consideration. Although there existed in Boston the type of industries which required great numbers of men, barriers prevented negroes in large numbers from entering them and as a result there was no great influx of migrants from the South.
