Scott's journal records, 'Friday 10-Saturday 11 March  Cut 8 folios of plans and tables for sledging journey' -- the entry excised from Scott's Last Expedition. These possibly the plans, based on Shackleton's published chart, to be used for the southern journey, of which Wright's is an example (and Keohane's, lot 96, a traced copy). Scott measured his march against Shackleton's in 1908-09, and used his map as a guide to his road to the Pole (he was later criticised by H.R. Mill for not pathfinding a different route). Bad weather on the Barrier put him about 6 days behind Shackleton to the Beardmore Glacier. In spite of being short-sighted, Wright navigated successfully for most of the southern journey, and has marked his progress in pencil on the chart on the outward journey to the top of the Beadmore Glacier.
