On account of which, veffels knowing this, coming 
from Malaga, &c. ufually, if they find the ftream 
againft them under Europa, come to an anchor be- 
hind the hill, and wait there for the tide, which will 
loon bring them in : others not knowing, or negledting 
this, have been, by the wefierly winds (in this cale 
luppofed) and the ftream, which they are lure to have 
againft them, either one or the other, hoifted up near 
Malaga again. 
As a farther confirmation of my idea, relating to 
the mid-ftream : being on guard at Europa, in the 
forenoon, there came a Spaniih xebeck from the weft, 
with little wind, and in time was becalmed right off 
a rock 1 fat on j where I continued almoft the whole 
day, to obferve her, driving back again with a mid- 
ftream, to appearance hall-chanel over, and edging 
outwards towards the Barbary fide ; when, about 
(even in the evening, with little or no wind as be- 
fore, flie returned, at a great rate, and fo continued, 
till night and diftance hid her in the Mediterranean. 
As to my fentiment, and what has given a ftrong 
bias thereto, with regard to the two fide-ftreams, 
viz. the tide on the Spaniih fide, and the tide on the 
Barbary fhore, I muft beg your patience to another 
obfervation. 
Setting lail with a light Levant, to pafs the ftrait to 
the weftward, the fihip I was in met a ftrong tide 
turning Cabrita point, which all the lail we could 
lpread was but barely enough to Item ; keeping, 
however, the Spanifh fhore, whilft others, near 
leventy, flood off for the middle, in an hour, or 
little more, the tide turned, and we made our way 
at a tolerable rate, till we were palled Tariifa, almoft 
oppofita
