The Associations that are left after these exclusions, naturally fall into two groups, viz.; those of the Owen movement, and those of the Fourier movement.

Robert Owen came to this country and commenced his experiments in Communism in 1824. This was the beginning of a national excitement, which had a course somewhat like that of a religious revival or a political campaign. This movement seems to have culminated in 1826; and, grouped around or near that year, we find in Macdonald's list, the names of eleven Communities. These were not all strictly Owenite Communities, but probably all owed their birth to the general excitement that followed Owen's labors, and may therefore, properly be classified as belonging to the Owen movement.

Fourierism was introduced into this country by Albert Brisbane and Horace Greeley in 1842, and then commenced another great national movement similar to that of Owenism, but far more universal and enthusiastic. We consider the year 1843 the focal period of this social revival; and around that year or following it within the forties, we find the main group of Macdonald's Associations. Thirty-four of the list may clearly be referred to this epoch. Many, and perhaps most of them, never undertook to carry into practice Fourier's theories in full; and some of them would disclaim all affiliation with Fourierism; but they all originated in a common excitement, and that excitement took its rise from the publications of Brisbane and Greeley.

Confining ourselves, for the present, to these two groups of Associations, belonging respectively to the Owen movement of 1826 and the Fourier movement of 1843, we will now give a brief statistical account of each Association; i.e., all we can find in Macdonald's collection, on the following points: 1, Locality; 2, Number of members; 3, Amount of land; 4, Amount of debt; 5, Duration. We give the amount of land instead of any other measurement of capital, because all and more than all the capital of the Associations was generally invested in land, and because it is difficult to distinguish, in most cases, between the cash capital that was actually paid in, and that which was only subscribed or talked about.

As to the reliability of these statistics, we can only say that we have patiently picked them out, one by one, like scattered bones, from Macdonald's heap. Though they may be faulty in some details, we are confident that the general idea they give of the attempts and experiences of American Socialists, will not be far from the truth.
