All Concerned

I have updated the log for 24 April 1916.  After careful reflection, the statement should read

No obs for Lat cd be obtained + Long of C.Belsham being only approximately 
know to us, allow 1 min 4 sec more.  Slow = 11min55sec

Instead of

No obs for Lat cd be obtained + Long of C.Belsham bein only opportunity 
knowing it is, allow 1 min 4 sec more, Slow = 11min55 sec

This subtle difference shows that Worsley didn't know the absolute location of 
Cape Belsham, rather, it was approximately known to him.

Our investigations have show that there was a map in 1822 by Powell of the 
Dove.  This map shows a distorted Elephant Island, with Cape Belsham clearly 
marked.  This map cascaded into various Sailing Directions in the 1800's, of 
which we can find 3.  Each of these Sailing Directions shows merely writes 
down the Lat Lon of Cape Belsham, as derived from the 1822 map.  

Then Admiralty chart 3205 is issued, a 1909 version of which is available.  
Elephant Island is still a misshapen mess, but the denotation of Cape Belsham 
has disappeared from the map.  We are attempting to find Sailing Directions 
for the South Shetlands for this first decade.

Worsley and Shackleton have indicated, via their books, that they have access 
to Admiralty Sailing directions and maps by Nordenskjold, a Swedish explorer 
to the region in 1901-03.  Nordenskjold's map shows a misshapen Elephant 
Island.  

Thus the only "Cape Belsham" reference dates back to 1822, and is carried 
forward in the Sailing Directions, which state that upwards of 2 degrees of 
error may be found in the longitudes in the Table of Places.

Best Regards
Brad
