tried, it cannot be expe6ted that fmgle fhips fhould venture 
fo far, as where there is fome fecurity provided againft an 
untoward accident. 
The veffels being now ready for fea, will fail with the 
fir ft South Weft erly monfoon, which generally fets in about 
the beginning of April. With this wind they will fleer to 
the Northward, along the coaft of China, beginning a more 
accurate furvey from the mouth of the river Kyana, or the 
Nankin River, in latitude 30°, which I believe is the utmoft 
limit of this coaft hitherto vifited by European fhips. As 
the extent of that deep gulf called Whang Hay, or the 
Yellow Sea, is at prefent unknown, it muft be left to the 
difcretion of the Commander, to proceed up it as far as he 
may judge prudent; but he muft be cautious not to entangle 
himfelf too far in it, left he fhould want time for the profe- 
cution of the remaining part of his enterprize. The fame 
difcretion muft be ufed, when he arrives in the Straits of 
TefToi, with refpecft to the iflands of Jefo, which, if the wind 
and weather be favourable, he will not lofe the opportunity 
of exploring. 
Having proceeded to the latitude of 51 0 40', where he will 
make the Southernmoft point of the ifland of Sagaleen, 
beyond which the fea of Okotzk is fufficiently known, he 
will fteer to the Southward, probably in the beginning of 
June, and endeavour to fall in with the Southernmoft of 
the Kurile iflands. Ooroop or Nadeegfda, according to the 
accounts of the Ruffians, will furnifh the fhips with a good 
harbour where they may wood and water, and take in fuch 
other refrefhments as the place may afford. Toward the 
end of June, they will fhape their courfe for the Shum- 
magins, and from thence to Cook’s River, purchafing, as
