Note 344 — BOOK V.

The province of Jalofo lies between the two rivers, the Gambia and the Zanago. The latter has other names in the several countries through which it runs. In its course it makes many islands, inhabited only by wild beasts. It is navigable for 150 leagues, at the end of which it is crossed by a stupendous ridge of perpendicular rocks, over which the river rushes with such violence, that travellers pass under it without any other inconvenience than the prodigious noise. The Gambia, or Rio Grande, runs 180 leagues, but is not so far navigable. It carries more water, and runs with less noise than the other, though filled with many rivers which water the country of Mandinga. Both rivers are branches of the Niger. Their waters have this remarkable quality; when mixed together they operate as an emetic, but when separate do not. They abound with great variety of fishes, and their banks are covered with horses, crocodiles, winged serpents, elephants, ounces, wild boars, with great numbers of others, wonderful for the variety of their nature and different forms.—Faria y Sousa.
