During the debate upon the Kansas-Nebraska bill in Congress, it does not seem to have been generally appreciated that it might, after all, turn out to be a Free-soil measure, and that the question whether it would be such or not in a specific case resolved itself into the problem of immigration. There lived, however, in the town of Worcester, Mass., a shrewd, far seeing business man, with whose shrewdness, however, ideality and patriotism were mingled in an uncommon degree, who immediately comprehended the situation from this point of view. This man was the now well known and universally honored Eli Thayer. Before the Kansas-Nebraska bill had become law, the idea in his mind had ripened into a wide-reaching plan. This plan was the organization of an emigrant aid society, with an immense capital, the purpose of which should be to foster emigration from the Northern Commonwealths and the European states into the Territories and the slaveholding Commonwealths of the Union, to the end that a Free-soil population should gain control of them, and prohibit or abolish slavery in them by their {409} own local acts. Mr. Thayer reasoned with himself that masters would be very timid about immigrating into a Territory with their slaves until the question should be determined whether slavery should have a legal existence in the Territory, while men without such impediments would go boldly forward and occupy the country, and vote the free status for the Territory; and again, that with only about one-fourth of the white population of the slaveholding Commonwealths pecuniarily interested in slavery, the immigration of a few thousand active anti-slavery men into these would finally turn the balance at the polls against the further existence of the institution in the slaveholding Commonwealths themselves. The plan was so comprehensive that most of Mr. Thayer's friends thought it visionary, and he modified it, after having obtained his charter from the legislature of Massachusetts, limiting it to the settlement of the Territories, and especially to that of Kansas Territory, by anti-slavery men. The organization, as thus finally effected, counted among its directors some of the purest, most patriotic, and most capable men of the country--Mr. A. A. Lawrence, Dr. Samuel Cabot, Mr. John Lowell, Mr. Moses H. Grinnell, Rev. Edward E. Hale, Rev. Horace Bushnell, Professor Benjamin Silliman, and others of the like fame and fortune. The way in which they proposed to accomplish their purpose was by lessening the hardships of the journey to the distant country, and the hardships of life in the new country. They proposed to organize the emigrants into companies, procure transportation for them at the most favorable rates, build hotels, boarding-houses, mills, school-houses, churches--in a word to send capital in advance of population, in order to attract a good, law-abiding population by planting for them the advantages and conveniences of civilization in the new country.
