See the account as given by Richard Lander: “On the 4th of May, we entered a town of prodigious extent, fortified with three walls of little less than twenty miles in circuit, with ditches or moats between. This town, called _Boo-hoo_, is in the latitude of about eight degrees forty-three minutes north, and longitude five degrees and ten minutes east. On the 17th, we came to _Roossa_, which is a cluster of huts walled with earth.” This traveller states that there is a kingdom in Africa called _Yaorie_, which is large, powerful, and flourishing, containing a city of prodigious extent. The wall surrounding it is of clay, very high, and in circuit between twenty and thirty miles. He mentions several other places, similarly enclosed by earth walls. It is easy to perceive the resemblance between these walled towns in central Africa, and the remains of similar works in this country, America.—[PRIEST.] * * * * * SCIENTIFIC ACQUIREMENTS OF ANCIENT BUILDERS IN THE WEST. As it respects the scientific acquirements of the builders of the works in the West, now in ruins, Mr. Atwater says: “When thoroughly examined, they have furnished matter of admiration to all intelligent persons who have attended to the subject. Nearly all the lines of ancient works found in the whole country, where the form of the ground admits of it, are right ones, pointing to the four cardinal points. Where there are mounds enclosed, the gateways are most frequently on the east side of the works, towards the rising sun. Where the situation admits of it, in their military works, the openings are generally towards one or more of the _cardinal points_. From which it is supposed they must have had some knowledge of astronomy, or their structures would not, it is imagined, have been thus arranged. From these circumstances, also, we draw the conclusion, that the first inhabitants of America emigrated from Asia, at a period coeval with that of Babylon, for here it was that astronomical calculations were first made, 2234 years before Christ. “These things could never have so happened, with such invariable exactness in almost all cases, without design. On the whole,” says Atwater, “I am convinced from an attention to many hundreds of these works, in every part of the West which I have visited, that their authors had a knowledge of astronomy. “Our ancient works continued into Mexico, increasing in size and grandeur, preserving the same forms, and appear to have been put to the same uses. The form of our works is round, square, triangular, semicircular, and octangular, agreeing, in all these respects with those in Mexico. The first works built by the Mexicans were mostly of earth, and not much superior to the common ones on the Mississippi.” The same may be said of the works of this sort over the whole earth, which is the evidence that all alike belong to the first efforts of men in the very first ages after the flood.
