“Ping-Pong at Its Greatest Height”

This photograph, taken in mid-winter at the highest point in His Majesty’s home domains, shows two of the meteorologists enjoying a game of ping-pong alongside the observatory on the summit of Ben Nevis. The photo was taken when the snow reached an average depth of 7ft., and during the progress of the game the temperature was as low as 18deg. Fahr. The table, composed as it was of a solid block of snow, covered with baize, served its purpose admirably, and the game, if not played under the most favourable climatic conditions, can at least boast of ‘high’ scoring.

— Robert H. Macdougall of Ben Nevis Observatory, quoted in Strand, August 1902
