But that the number can be gradually diminished, _till utterly
extinguished_, may be made to appear, it is believed, from a
little arithmetical calculation....' 'It has been said that the
entire shipping of the country, both public and private, would
hardly be competent for an object of this magnitude. But careful
calculation has proved, that one eighteenth of the mercantile
shipping alone, entirely devoted to the enterprise, is competent
to carry it into complete consummation. And why might not our
brilliant and growing _navy_ aid to some extent the humane and
patriotic cause? If necessary, why might not _the marine of
other lands_ be chartered? Strange indeed it is if shipping
enough could be found half a century ago to reduce hundreds of
thousands of this race in a single year to a wretched vassalage,
and in this age of augmented light, and wealth, and improvement
in every art, enough cannot be found for the single benevolent
object before us!'--[Rev. Baxter Dickinson's Sermon delivered in
Springfield in 1829.]

'How much soever we may regret that so little is done for the
intellectual and moral improvement of the free colored
population, as the surest preventive against crime, still we
must acknowledge it is in vain to attempt raising their
character to a level with that of the other inhabitants. They
must find an asylum beyond the influence of the white
population, or the majority of them will _ever be found unworthy
of the boon of freedom_. There must be that asylum for them, or
we despair of ever being able to improve materially their
condition, or to eradicate slavery from our soil, and thus
prevent the awful catastrophe which threatens our republic. They
must be furnished with facilities to leave this country and
establish themselves in a community of their own.'--'I have
alluded to the difficulties which are presented to the minds of
benevolent and conscientious slaveholders, wishing to manumit
their slaves. From what has been said, it is evident that unless
some drain is opened to convey out of the country the
emancipated, the laws which relate to emancipation, must
continue in force with all their rigor. Without this drain, we
can hope for no repeal, or relaxation of those laws where the
slaves are very numerous. The mass of slaveholders can never let
