The month of May passed with few incidents of importance.  Hurley, our handy man, installed our small electric-lighting plant and placed lights for occasional use in the observatory, the meteorological station, and various other points.  We could not afford to use the electric lamps freely.  Hurley also rigged two powerful lights on poles projecting from the ship to port and starboard.  These lamps would illuminate the “dogloos” brilliantly on the darkest winter’s day and would be invaluable in the event of the floe breaking during the dark days of winter.  We could imagine what it would mean to get fifty dogs aboard without lights while the floe was breaking and rafting under our feet.  May 24, Empire Day, was celebrated with the singing of patriotic songs in the Ritz, where all hands joined in wishing a speedy victory for the British arms.  We could not know how the war was progressing, but we hoped that the Germans had already been driven from France and that the Russian armies had put the seal on the Allies’ success.  The war was a constant subject of discussion aboard the ‘Endurance’, and many campaigns were fought on the map during the long months of drifting.  The moon in the latter part of May was sweeping continuously through our starlit sky in great high circles.  The weather generally was good, with constant minus temperatures.  The log on May 27 recorded: 

“Brilliantly fine clear weather with bright moonlight throughout.  The moon’s rays are wonderfully strong, making midnight seem as light as an ordinary overcast midday in temperate climes.  The great clearness of the atmosphere probably accounts for our having eight hours of twilight with a beautiful soft golden glow to the northward.  A little rime and glazed frost are found aloft.  The temperature is -20° Fahr.  A few wisps of cirrus-cloud are seen and a little frost-smoke shows in one or two directions, but the cracks and leads near the ship appear to have frozen over again.”

Crean had started to take the pups out for runs, and it was very amusing to see them with their rolling canter just managing to keep abreast by the sledge and occasionally cocking an eye with an appealing look in the hope of being taken aboard for a ride.  As an addition to their foster-father, Crean, the pups had adopted Amundsen.  They tyrannized over him most unmercifully.  It was a common sight to see him, the biggest dog in the pack, sitting out in the cold with an air of philosophic resignation while a corpulent pup occupied the entrance to his “dogloo.”  The intruder was generally the pup Nelson, who just showed his forepaws and face, and one was fairly sure to find Nelly, Roger, and Toby coiled up comfortably behind him.  At hoosh-time Crean had to stand by Amundsen’s food, since otherwise the pups would eat the big dog’s ration while he stood back to give them fair play.  Sometimes their consciences would smite them and they would drag round a seal’s head, half a penguin, or a large lump of frozen meat or blubber to Amundsen’s kennel for rent.  It was interesting to watch the big dog play with them, seizing them by throat or neck in what appeared to be a fierce fashion, while really quite gentle with them, and all the time teaching them how to hold their own in the world and putting them up to all the tricks of dog life.
