Autograph letter signed ('Ernest Shackleton'), to Cyril Longhurst, the Secretary of the British National Antarctic Expedition, reading "Will you give the bearer all the papers relating to orders given, to find also if any orders have been sent out lately, let me have them. I am making up the work down here. Of course I do not want anything out of the Balloon box, or the explosives, mostly provisions and general stores: if you send the various boxes down, I will have them locked up and returned directly we get through them. I don't want any box dealing with the scientific part or instruments. I am sorry to trouble you but this is most important", two pages, mailing folds, some toning and yellowing around folds, a water smudging on the verso, 4to , National Antarctic Expedition, University Building, Burlington Gardens, London, 17 January 1901.
