At Prestwick. This was a fairly good day with some sunshine + medium Temp. Calm + not very clear. Arran visible but not Ailsa [Craig]. Towards evening it became clearer. I walked along + called for Kitty1 but they were all at church so I strolled round the shore. There was quite a crowd of people being Glasgow holidays2. I saw + watched a swimmer a good way out doing various manoeuvres in the sea + to my surprise it turned out to be a woman. Ernest3 too [sic] Kitty, her father4 + me for a run to Monkton, Dundonald, Kilmarnock, Galston, New Milns, Darvel, Muirkirk + home5. It was quite enjoyable but Ernest is rather a – I wouldn’t say reckless – but just a little risky. Got back to supper at Ladyton6 at 7.30. Kitty + the others came along later + both Kitty + Ernest sang.
