revive and under this impulse he moved again, this time to Dakota,
where he remained long enough to transform a section of prairie into
wheat land before he took the final stage of his western journeyings
to southern California. Here he was surrounded by neighbors whose
migration had been not unlike his own, and to the same sunny region
another relative found his way "by way of a long trail through Iowa,
Dakota, Montana, Oregon, and North California."

When the last frontier had vanished, it was seen that men of this
American stock had penetrated into every valley, traversed every
plain, and explored every mountain pass from Atlantic to Pacific. They
organized every territory and prepared each for statehood. It was the
enterprise of these sons and grandsons and great-grandsons of the
Revolutionary Americans, obeying the restless impulse of a pioneer
race, who spread a network of settlements and outposts over the entire
land and prepared it for the immigrant invasion from Europe. Owing to
this influx of foreigners, the American stock has become mingled with
other strains, especially those from Great Britain.

The Census Bureau estimated that in 1900 there were living in the
United States approximately thirty-five million white people who were
descended from persons enumerated in 1790. If these thirty-five
million were distributed by nationality according to the proportions
estimated for 1790, the result would appear as follows:

English 28,735,000
Scotch 2,450,000
Irish 665,000
Dutch 875,000
French 210,000
