Working the theodolite in the pack ice.

A port stern view of the exploration ship Southern Cross (1886) alongside pack ice. An unidentified man is using a theodolite on a tripod in the centre foreground. Dogs are waiting singly or in groups on the ice off the port side of the ship.

Original print in the album has no caption, although in Borchgrevink's book the same photograph was captioned 'Theodolite work in the pack' (page 67).
