The aggregate amount of the postage received at the different
post-offices must always depend, in a greater or less degree, upon the
extent and frequency of the mail transportation by which such offices
are supplied, and the rates of postage charged, as well as upon the
number, education, character and occupation of the population within the
delivery of such offices. Other causes, some of them local or temporary,
may at times affect the revenue of an office, but only the population of
the neighborhood, the frequency and extent of the transportation
service, and the general rates of letter postage, will be here
considered.

The first census under the authority of the United States was taken in
1790; probably in July and August of that year. In that portion of New
York lying west of the old Massachusetts preemption line it was taken by
General Amos Hall, as Deputy Marshal, and an abstract of his list or
census-roll is given in Turner's "History of Phelps and Gorham's
Purchase." The number of heads of families then residing west of Genesee
River, and named in that list, was 24; but it is probable that the
deputy marshal did not visit this locality, as neither Winney the Indian
trader, nor Johnston the Indian agent and interpreter, is named;
although it is probable that both of them resided here. Winney, it is
quite certain, was here in 1791, and it is supposed came about 1784.

The whole population west of the Massachusetts preemption line, which
was a line drawn due north and south across the State, passing through
Seneca Lake and about two miles east of Geneva, as given by Turner from
General Hall's census-roll, was 1,084, as follows: males, 728; females,
340; free blacks, 7; slaves, 9. In the State census report of 1853, the
population of Ontario County in 1790 (which county then embraced all
that territory) is stated at 1,075. The difference between the two
statements is caused by the omission of the slaves from the latter
statement. In 1800 the population of the same territory (then the
Counties of
