"We must have been care-free this morning,..., for the next thing we set out to do was nothing more serious than to teach the porters how to snowball. At first they thought it the poorest of pastimes, but that was because they believed that the rules did not provide for retaliation; once they had grasped that essential principle they entered into the game with great gusto. And in the afternoon, while we were sleeping, they laid up a stock of ammunition and waited for the fuel porters to top the lip of the valley, and then pelted them mercilessly. ~ E.A.T. Dutton"
