non-intercourse policy.

It is only necessary to add a few remarks, from the speech of Mr.
Glover, in summing up the testimony. He said: "From this ground see what
is put in hazard; not merely a monied profit, but our bulwark of
defense, our power in offense--the acts and industry of our Nation.
Instead of thousands and tens of thousands of families in comfort, a
navigation extensive and enlarging, the value and rents of lands yearly
rising, wealth abounding, and at hand for further improvements, see or
foresee, that this third of our whole commerce, that sole basis of our
Empire, and this third in itself the best, once lost, carries with it a
proportion of our national faculties, our treasure, our public revenue,
and the value of land, succeeded in its fall by a multiplication of
taxes to reinstate that revenue, an increasing burden on every
increasing estate, decreasing by the reduced demand of its produce for
the support of Manufactures, and menaced with a heavier calamity
still--the diminution of our Marine, of our seamen, of our general
population, by the emigration of useful subjects, strengthening that
very country you wish to humble, and weakening this in the sight of
rival powers, who wish to humble us.

"To recapitulate the heads of that material evidence delivered before
you, would be tedious in me, unnecessary in itself. Leaving it,
therefore, to its own powerful impression, I here add only, in a general
mode of my own, that of the inhabitants of those Islands, above four
hundred thousand are blacks, from whose labor the immense riches there,
so distinctly proved at your bar, are derived, with such immense
advantage to these kingdoms. How far these multitudes, if their
intercourse with North America is stopped, may be exposed to famine, you
have heard. One-half in Barbadoes and the Leeward Islands, say one
hundred thousand negroes, in value at least twenty millions of dollars,
possibly, it grieves me to say probably, may perish. The remainder must
divert to provisions the culture of the produce so valuable to Great
Britain. The same must be the practice in great part throughout Jamaica
and the new settled acquisitions. They may feel a distress just short of
destruction, but must divert for subsistence so much labor as, in
proportion, will shorten their rich product."[114]

The North American colonies could not have devised a measure so alarming
to Great Britain, and so well calculated to force Parliament
