IN a voyage to the South land, called HollarMa Nova, it has 
been dilcovered that the Ibil oF the country is very barren and 
]ikeadelart3 no fre(h-water rivers have been found, but fome 
falt-water ones ^ as alio no four-footed beafts , except one as great 
as a dog, with long ears, that lives in the water as well as on the 
land : J3lack-fwans, parrots and many lea-cows were found there, 
as alfo a lake, whofe water feemed to be red, becaule of the red- 
nefs of Its bottom, and along the ihore there was iome lalt 5 our 
people fiw but 12 of the natives, all as black as pitch and ftark 
naked, who were fo nnuch affrighted at feeing of them that they 
could not be brought to a converfation or a meeting • they lodge

fcented trees, out of the wood of which may be drawn oil fmel- 
lina like a rofe, but for the reft they were li-nall mean trees, there 
were alio found fome birds nefts of a prodigious bignels, {o that fix 
men could not, by ftretching out their arms fathom one of them, 
but the fowls were not to be found ^ there was great ftore of oyfters, 
lobfters and crabs 5 as alfo of ftrange Ibrts of fi/h; there were 
alio infinite numbers of flies which are very troublelbme3 they 
faw a great many footfteps of men and children, but all of an 
ordinary bignels 3 the coaft is dangerous and full of rocks.
