been done, and possibly meet an extension of Palmer's Land, more to 
the westward : if you should succeed, you will trace it to the east- 
ward, and return by the southern and eastern side of it, to this 
anchorage, thus circumnavigating this land, unless you should re- 
ceive further information from me. 
5th. Herewith you will receive a Dipping and Intensity Needle, 
with which you will make observations on any floe of ice that may be 
accessible. 
6th. In your progress to the eastward from Cook's Ne Plus Ultra, 
105° W., you will endeavour to get more and more to the southward, 
and to pass to the southward of the two small islands called Peter I. 
and Alexander, (the farthest land south discovered by the Russians 
in 1821,) and then fall in with what Briscoe denominated Graham's 
or Palmer's Land, (its proper American name.) I am of the opinion 
that it extends much farther to the southward and westward, than 
where Briscoe saw the Adelaide Mountains, and that the land 
stretches or trends to the west. This will be a very important 
discovery, and the lateness of the season is very advantageous for the 
exploration, if the summer should have proved an open one. My 
reason for believing in the extension of this land is, that such large 
quantities of ice-islands, which are frequently drifted to the north and 
west of Cape Horn, must have some land to form on, and we are 
aware that all the ice formed about the South Shetlands goes to the 
eastward. 
7th. You must endeavour to reach the southward of Peter I. and 
Alexander Islands, or south of the Russian track. 
8th. You will fill up the skeleton chart as you progress, and treat 
the main ice and ice-islands as if they were land, by inserting them 
on it, which will be an important addition to our knowledge, if we 
only obtain the line of ice in those seas ; it does not appear ever to 
have been done by southern navigators accurately ; had it been so, 
our task would have been more easy. 
9th. I should think the winds from the west to the east will be so 
as to enable you to choose positions to shield your ship under the lee 
of the icy shore (if I may be allowed the expression). 
10th. In the event of your reaching the main land, or a channel 
leading to it, if one offers, you will despatch the Flying-Fish, with 
such officers as you may think fit, to make the recognizance of it, if 
time should not allow a full survey. 
11th. It is desirable that the extent and circumference of any
