tempts to add to my collection of specimens of African produce, I
was favoured with a sample of gum ruber astringens, of cotton from the
Gambia, of indigo and musk, of long pepper, of black pepper from Whidah, of
mahogany from Calabar, and of cloths of different colours, made by the
natives, which, while they gave other proofs of the quality of their own
cotton, gave proofs also, of the variety of their dyes.

I made interest at the Custom-house for various exports and imports, and
for copies of the muster-rolls of several slave-vessels, besides those of
vessels employed in other trades.

By looking out constantly for information on this great subject, I was led
to the examination of a printed card or table of the dock-duties of
Liverpool, which was published annually. The town of Liverpool had so risen
in opulence and importance, from only a fishing-village, that the
corporation seemed to have a pride in giving a public view of this
increase. Hence they published and circulated this card. Now the card
contained one, among other facts, which was almost as precious, in a
political point of view, as any I had yet obtained. It stated, that in the
year 1772, when I knew that a hundred vessels sailed out of Liverpool for
the coast of Africa, the dock-duties amounted to 4552_l_., and that in
1779, when I knew that, in consequence of the war, only eleven went from
thence to the same coast, they amounted to 4957_l_. From these facts, put
together, two conclusions were obvious. The first was, that the opulence of
Liverpool, as far as the entry of vessels into its ports, and the
dock-duties arising from thence, were concerned, was not indebted to the
Slave-trade; for these duties were highest when it had only eleven ships in
that employ. The second was, that there had been almost a practical
experiment with respect to the abolition of it; for the vessels in it had
been gradually reduced from one hundred to eleven, and yet the West Indians
had not complained of their ruin, nor had the merchants or manufacturers
suffered, nor had Liverpool been affected by the change.

There were specimens of articles in Liverpool, which I entirely overlooked
at Bristol, and which I believe I should have overlooked here, also, had it
not been for seeing them at a window in a shop; I mean those of different
iron instruments used in this cruel traffic. I bought a pair of the iron
hand-cuffs with which the men-slaves are confined. Th
