Note 86 — PAPERS ON AMERICAN SUBJECTS, DURING THE REVOLUTIONARY TROUBLES.
Reading edition
Strangers excluded, some parts of the northern colonies double their numbers in fifteen or sixteen years; to the southward they are longer, but, taking one with another, they have doubled by natural generation only, once in twenty-five years. Pensylvania, I believe, including strangers, has doubled in about sixteen years. The calculation for February 1766 will not then suit 1779. B. V.
