As this work is not intended to throw light on the African slave-trade further than in as far as it concerns South America, it is not necessary to follow Sir John throughout all his nefarious proceedings on the coast of Africa. But one of his voyages, in the course of which he proceeded with his usual cargo, in the year 1564, to _Cape de la Vala_, has for us unusual interest, inasmuch as in the course of its narrative we find the first mention, among English writers, of the potato. It is well known that Raleigh and certain of his companions, at a much later date, brought home with them that root from _Virginia_. It is the case likewise, that, some time before this voyage of Raleigh, Drake had introduced the same plant to these islands; but that our first acquaintance with the potato is due to Hawkins and his expedition of the above-mentioned year will appear from the following extract:-- “Here perceiving no trafficke to be had with them, nor yet water for the refreshing of our men, we were driven to depart the twentieth day, and the 2 and twentieth we came to a place in the maine called _Cumana_, whither the captaine going in his pinnisse, spake with certaine Spaniards of whom he demanded trafficke, but they made him answere, they were but souldiers newely come thither, and were not able to by on negro; whereupon hee asked for a watring place, and they pointed him a place two leagues off, called _Santa Fè_, where we found marvellous goodly watring, and commodious for the taking in thereof; for that the fresh water came into the sea, and so our shippes had aboord the shore twentie fathome water. Neere about this place inhabited certaine Indians, who the next day after we came thither came down to us, presenting mill and cakes of breade, which they had made of a kinde of corne called maiz, in bignesse of a pease, the eare whereof is much like to a teasell, but a spanne in length having thereon a number of granes. Also they brought down to us Hennes, Potatoes and Pines, which we bought for beades, pewter whistles, glasses, knives and other trifles. These potatoes be the most delicate rootes that may be eaten, and doe farre exceed our passeneps or carets.”[S] * * * * *
