12-foot Nansen-type dog sledge. It is made of wood with a bent bamboo front, and weighs about 100 ibs unloaded. It has braced wooden upright handlebars with a canvas bag attached to take spare mitts and other impedimenta. There is a cross bar on which the compass would have been mounted.. A back picket serves to stop the sledge and a heavy iron picket (pointed angle iron) for sea ice, is kept in a canvas bag on the left brace. A rope under the front serves as a brake (chain brakes could be used on ice). A nylon rope was used for lacing over the load, which would be two boxes high maximum. Two plywood blocks (deadmen) were used to picket to at night. Among other equipment are night traces, handholds for ski-drawing, a trail rope, an ice axe used a s a front picket when clipped to the trace of the front dog, and a rope dog thumper. Inscriptions: 'Nansen dog sledge' in black marker pen on the right upright. 'R/C/3188' in black marker pen on the back of the left runner. 'Camp' on the ice pick. Dogs were first used by the British Antarctic Survey in 1945. The last dogs were removed from the British Antarctic base at Rothera in February 1994.
