24 TRAVELS IN 
Having proceeded, in this manner, to mark down the route 
and the chains of mountains on each fide of it, as far as the 
drofdy of Graaf Reynet, and from thence to the fea-coaft at 
Algoa Bay, I here joined Lieutenant Rice of the navy, an able 
and intelligent navigator, who had been fent in his Majefty's 
brig the Hope, under the inftrudions of Rear- Admiral Pringle, 
to make a furvey of this bay, and of the coaft and bays from 
hence to the Cape. Here we made repeated obfervations for the 
latitude, but had no opportunity, during our ftay, of taking 
the angular diftance of the Sun and Moon, in order to deter- 
mine the longitude. I therefore retained the longitude arifmg 
from the data I procured in the manner already mentioned, 
although it differed a little from Mr. Rice's, being about a de- 
gree more eafterly. His longitude was the refult of the log- 
reckoning ; but as the currents that, at all feafons of the year, 
are found to fet in one direction or another upon the Bank of 
L'Aguillas, render the log- reckoning very uncertain ; and, as 
the refult of obfervations, afterwards made, gave about the 
mean longitude between ours, it did not appear important to 
make any change in the chart. I was moreover induced to 
retain the longitude, brought out by computation of the diftance 
and direction travelled, on perceiving that it differed not half 
a degree with that of Algoa Bay, as laid down in the excellent 
chart of the Bank L'Aguillas, publifhcd by Major Rennell. 
A difagreement, however, will be found in fome of the lon- 
gitudes, as given in the text, and thofe marked in the chart, 
for the knowledge of which I am indebted to the writers of 
the Critical Review. This difference, which is not material,
