Daily log entries for January, crossing the Antarctic Circle on 17 January with the Adventure still in company. The entries include observations on ice-islands seen and on the difficulty of navigating in such conditions: ‘the rigging is so encumbered with ice that it is with the utmost difficulty the ship is worked’ [RGO 14/58: 16v]. An entry for 8 January reports that boats were sent out to collect a cargo of ice for drinking water, which Wales describes as ‘more precious to us than gold’ [RGO 14/58: 18]. Wales also reports on his equipment, recording that on 22 January he had placed a thermometer near each of the timekeepers, which were kept on each side of the cabin, in case the fire in the cabin affected their accuracy [RGO 14/58: 21v], while on 29-30 January he mentions having problems with his marine barometer [RGO 14/58: 23v].
