be the case, the population has more than doubled each thirty years since their arrival upon American soil,—which is about as rapid a rate of increase as can be found among any people in the world, perhaps only surpassed by the population of Virginia; which commonwealth, starting with an original English emigration which could not have exceeded one hundred thousand, counts at the present day not less than six million descendants, or about twice as many as there would be if each generation only doubled the numbers of the preceding. There is yet another separate people on the American soil which has been here for about six generations without any addition from abroad: these are the so-called Pennsylvanian Germans. I shall not take time to do more than mention them, for they, without recent European admixture, show the same evidences of continued vigor that is presented by the Virginian British and the Canadian French blood. Their progeny are to be counted by millions; and though they, like the Canadian French, have shown as yet little evidence of intellectual capacity, this may be explained by the extreme isolation that their language and customs have forced upon them. Imperfectly as I have been able to present this important series of facts, it is enough to make it clear that they are mistaken who think that the recent emigrations from Europe have helped to maintain the vigor of the American people. It seems more likely that, so far from adding to the strength of the older stocks, the newer comers, mostly of a lower kind of folk than the original settlers, have served rather to hinder than to help the progress of the population which came with the original colonies. These considerations may be extended, by those who care to do so, by a study of several other isolated peoples in this country,—the German colonies of Texas, the Swiss of Tennessee, and several others; all of which have prospered, and all of which have gone to prove that the climate of North America is singularly well fitted for the use of Northern Europeans. No sufficiently large colonies of Italians, Spanish, or Portuguese have ever been planted within the limits of the present United States to determine the fitness of its conditions for the peoples of those States. There is no reason, however, to believe that they would not have succeeded on this soil if fortune had brought them here.
