Footnote 201: The claims put forward by Douglass Campbell, _The Puritan in Holland, England and America_, are now generally considered as thoroughly unsound. _Cf._ the article by the Dutch historian, H. T. Colenbrander, “The Dutch Element in American History,” in _Annual Report of the American Historical Association_, 1909, pp. 191-203. Also, in the same report, Ruth Putnam, “The Dutch Element in the United States,” pp. 203-19. Although there were other English in Leyden, and, therefore, the size of Robinson's congregation is difficult to determine accurately, it seems to have numbered about two hundred at the time that its members were considering their third emigration, and had decided to leave Holland.[202] The reasons for this decision, as given by Bradford, were the difficulty, for many, of making a living, and the unlikelihood of attracting others; the possibility that they would themselves disperse in time; the temptations which beset their children; and their desire to spread the gospel in the new world.[203] To these, Winslow, who had joined the group about 1617, added their wish to remain Englishmen; the inability to give their children as good an education as they themselves had received; and the somewhat ambiguous reason, “how little good we did or were like to do to the Dutch in reforming the sabbath.”[204] Their motives were, therefore, partly patriotic, partly economic, and partly religious, the same which, in shifting proportions and embodied in a very varied assortment of personalities, we find as mainsprings of colonization from the beginning. The one constant factor is the economic. No matter what other motives may have induced any one, from John Cabot to the last arrival at Ellis Island, to turn his face westward, added to them has ever been the hope of bettering his economic condition. America has always offered comparative material prosperity to the most idealistic as well as to the most sordid. When this factor ceases to operate, as in time, perhaps a short time, it must, American history will enter upon a new phase.
