Alan sent off another routine, for factorising numbers, to Manchester on 2 August.
Then he went on holiday with Neville in Switzerland.
It was the first escape from austerity England, and they could hardly believe the fresh country foods.
The trip was made on the travel allowance of 25 pounds, in the form of five crisp five-pound notes.
They did it by cycling and staying in youth hostels: they trod glaciers and scaled mountains and had the usual smouldering arguments of people on holiday together, as when Alan let his bicycle break down through inattention, or was keen on another young man in the hostel.
It was not quite E.M. Forster's greenwood, but as near as he had ever approached it.
The summer continued with a week in the Lake District at Pigou's cottage, with Peter Matthews.
Pigou was very keen on mountaineering, and even more, with a pre-Carpenter innocence, on Wilfrid Noyce the young mountaineer. Alan took care to practise rock-climbing on the King's College gate with Peter Matthews before they went.
Alan did some easy climbing, but mostly trotted round Buttermere in short shorts.
