Tuesday, 26 September 1876 (14 September) — Difficult Horses and Russian Coaching

The horse I have been spoiling with lumps of sugar, as you know, having had two rides without a saddle, now refuses to be harnessed at all. From lively he has become ungovernable — he gallops, he leaps; a true cheval soumis, as they call the trace-horse in Russia that is harnessed to the side and which bounds and caracoles with its head bent outward. I mean to bring him to reason, and today I went for a drive of fifty metres in the tilbury

Notes

The cheval soumis (literally "trace-horse") is the side-horse in a Russian troika, which runs in a controlled sideways canter with its head turned outward while the centre horse trots straight.
