Rushton, also, had the boldness, though then living in Liverpool, to affix his name to his work. These were the only persons whom I knew for some time after my arrival in that place. It may not, perhaps, be necessary to enter so largely into my proceedings at Liverpool as at Bristol. The following account, therefore, may suffice:-- In my attempts to add to my collection of specimens of African produce, I was favoured with a sample of gum ruber astringents, of cotton from the Gambia, of indigo and musk, of long pepper, of black pepper from Whidàh, 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.
