IN the following Inquiry I have inserted four engraved Charts, in order to illustrate the subjects treated of in the Book, by a method approved of both in this and in other countries. {4}
The Chart, No. 1, representing the rise and fall of all nations or countries, that have been particularly distinguished for wealth or power, is the first of the sort that ever was engraved, and has, therefore, not yet met with public approbation.
It is constructed to give a distinct view of the migrations of commerce and of wealth in general. For a very accurate view, there are no materials in existence; neither would it lead to any very different conclusion, if the proportional values were ascertained with the greatest accuracy.
