A VOYAGE TO 
17S0. Eaft, and the centre of the hofpital South 53’ Weft, in 
. - feven fathoms. But if the South Eaft winds have not done 
blowing, it is better to ftay further out in eight or nine fa¬ 
thoms. The bottom is fandy, and the anchors fettle con- 
liderably before they get hold. All the North part of the 
Bay is low fandy land, but the Eaft fide is very high. About 
fix miles Eaft of Noah’s Ark lies Seal Illand, the South part 
of which is faid to be dangerous, and not to be approached, 
with fafety, nearer than in twenty-two fathoms. Off the 
Cape of Good Hope are many funk rocks, fome of which 
appear at low water; and others have breakers conftantly 
on them. 
The latitude of the anchoring-place in Si¬ 
mon’s Bay, by obfervation - - - 34 0 20" South. 
The longitude - - - - 18 29 Eaft. 
Dip of the South end of the magnetic needle 46 47 
Variation of the compafs - - - 22 16 Weft. 
On the full and change days, it was high-water at 5* 55"' 
apparent time; the tide rofe and fell five feet five inches; 
at the neap tides, it rofe four feet one inch. 
From the obfervations taken by Mr. Bayly and myfelf, 
on the nth of this month, when the Cape of Good Hope 
bore due Weft, we found its latitude to be 34 0 23' South, 
which is 4' to the Northward of its pofition, as determined 
by the Abbe de la Caille. 
Having completed our victualling, and furnifhed our- 
felves with the neceffary fupply of naval ftores, we failed 
out of the Bay on the 9th of May, and on the 14th, we got 
into the South Eaft trade-wind, and fteered to the Weft ward 
Wednef. 31. of the iflands of St. Helena and Afcenfion. On the 31ft, 
being
