of the United States and Territories of North America. 69 
to those last mentioned, were found without slaves, viz. New 
Hampshire, Vermont, Ohio, and the territory of Michigan ; 
their numbers having rapidly decreased from one census to the 
other, so as in the last enumeration to have disappeared alto- 
gether. In New Hampshire, for example, the decrement from 
1790 to 1800 was 94.9 per cent. ; and this diminution having 
been probably continued with still greater rapidity, during the 
succeeding periods, the whole slave population had vanished be- 
fore the enumeration of 1810 ; nor were any traces of their ex- 
istence to be found in 1820. In Rhode Island, the decrements 
will be perceived to be rapid and continuous, during the whole 
period embraced by the table ; and, in the last census, the slaves 
were found to amount only to 45 in number, and these will 
most probably disappear before the next census of the people. 
In Connecticut, the decrements have been increasing through 
each period, leaving, in 1820, only 97 slaves. In Vermont, in 
the year 1790, only 16 slaves were to be found, but not one in 
the succeeding census. In the State of New- York, the slaves, 
in 1790, amounted to above 21,000. In the succeeding ten 
years they received a feeble decrement of 3.4 per cent. ; but, 
in the following period, it amounted to 37.3 per cent. ; and in 
the decade from 1810 to 1820, the rate of decrease was conti- 
nued at the rate of 32.8 per cent. ; leaving, at the end of the 
period last mentioned, only 10,088 slaves ; so that the time may 
not be far distant, when the inhabitants of this large and po- 
pulous province will have to boast that every native of its soil 
is free. 
In the first of the periods included in this table, New Jersey 
received an increment of 8.7 per cent, to its slaves ; but, in the 
succeeding period, a decrement of a greater magnitude was 
found; and, during the last period, this decrease became still 
greater, amounting to 30.4 per cent., leaving only 7557 slaves 
at the last census. In Pennsylvania, the slaves have declined 
very considerably since 1790, having diminished, in the first in- 
terval, 54.3 per cent. ; in the second, 114.6 per cent. ; and, in 
the third, 73.5 per cent. ; so that the slaves which, in 1790, 
amounted to nearly 4000, were reduced, in 1820, to a little 
more than 200. Delaware, on the contrary, which had recei- 
ved considerable decrements in ihe first and second periods, in
