NavList:

Thanks David  for finding this.what a great read! (very amusing too, e.g, he would  have thrown the stowaway Ballantyne over board with a parachute if they been over land!). The navigator was called Cooke of all things. Here is a good bit.

"Scott is able by skilful handling to keep the
ship in these thick clouds to avoid superheating.
At the same time, he judges it so nicely that
Cooke, standing on the top of the ship, is able
to get observations with sextant on sun and cloud
horizon his eye being practically on a level with
the cloud horizon, the only thing peeping up above
the top of the cloud-bank being the top of his
head, which is functioning in the same way as
a submarine periscope !

What a strange sight it would have been to
another passing aircraft to see a man's head
skimming along the top of a cloud-bank at
forty knots !

Brilliant read!
