Green Hill Country
The travellers had supper under some birches after walking ‘for about three hours’ (Three is Company; Bk 1); say 8 or 9 miles. This must have been three hours in all, not just since crossing the Water, as they reached their first camping place at ‘nearly midnight’ and had started out soon after sunset, around 7p.m. at that time of year. One has reason to suppose that the seasons, and therefore the times of sunrise and sunset, were approximately the same in the Shire as those now applicable in England.
We reckon that they did not travel more than about 14 or 15 miles that first evening.
