Tuesday night (21 August 1917)

Plenty of aeroplanes about this evening; saw them do the spiral or corkscrew descent.  Was in the riding for the first time today and was the first one to be classed “1” (1, 2, and 3 class) so can’t have forgotten how to ride.  R. is on guard tonight and I sent him facetious messages in semaphore across the parade ground, including “Crapaud” and almost upset the solemnity due to his duty.  Got “one on to” R. today.  Found an enormous sock, big enough for an elephant, and left it on his bunk – he has stupendous feet – elevens.

[Crapaud is a French word meaning “toad”]
