Thus in the last decade about 4 millions of the total
increase of population is in the second group, and
3,700,000 in the last group. At this rate, clearly, the
increase of population in the second group in ten years
from 1880, if all agricultural, would be such as nearly
above stated, which includes towns of a smaller size than are reckoned
in this comparative table:

1 To prevent misunderstanding, it should be noted that the figures
per square mile in this table refer to the whole population, whereas in
the table on p. 30 the figures relate to the rural population only.
