One of a group of 15 watercolours made by Conrad Martens of Robert Fitzroy's voyage of the 'Beagle'. It depicts the 'Beagle', commanded by Fitzroy and carrying Charles Darwin, sailing through the Beagle Channel in the Tierra del Fuego archipelago on 3 March 1834. The mountains known as the 'Dogs Jaws' (3,900 feet) can be seen in the background behind the ship. See 'Conrad Martens's "Beagle" Pictures', no.138, in R.D.Keynes (ed.) 'The Beagle Record...' (CUP, 1979), pp. 389-402. The drawing was developed from a view in Martens's fourth voyage sketchbook which Keynes lists as no. 137. For notes on Martens, see PAF6227.
