The feeling, however, must have been very slight, since it permitted me to become interested in the appearance and actions of a few sparrows inhabiting the temple. The common sparrow is parasitical on man, consequently but rarely found at any distance from human habitations, and it seemed a little strange to find them at home at Stonehenge on the open plain. They were very active carrying up straws and feathers to the crevices on the trioliths where the massive imposts rest on the upright stones. I noticed the birds because of their bright appearance: they were lighter coloured than any sparrows I have ever seen, and one cock bird when flying to and fro in the sunlight looked almost white. I formed the idea that this small colony of about a dozen birds had been long established at that place, and that the change in their colouring was a direct result of the unusual conditions in which they existed, where there was no shade and shelter of trees and bushes, and they were perpetually exposed for generations to the full light of the wide open sky. On revisiting Stonehenge after an interval of some years I looked for my sparrows and failed to find them. It was at the breeding-season, when they would have been there had they still existed. No doubt the little colony had been extirpated by a sparrow-hawk or by the human guardians of "The Stones," as the temple is called by the natives. It remains to tell of my latest visit to "The Stones." I had resolved to go once in my life with the current or crowd to see the sun rise on the morning of the longest day at that place. This custom or fashion is a declining one: ten or twelve years ago, as many as one or two thousand persons would assemble during the night to wait the great event, but the watchers have now diminished to a few hundreds, and on some years to a few scores. The fashion, no doubt, had its origin when Sir Norman Lockyer's theories, about Stonehenge as a Sun Temple placed so that the first rays of sun on the longest day of the year should fall on the centre of the so-called altar or sacrificial stone placed in the middle of the circle, began to be noised about the country, and accepted by every one as the true reading of an ancient riddle. But I gather from natives in the district that it is an old custom for people to go and watch for sunrise on the morning of June 21. A dozen or a score of natives, mostly old shepherds and labourers who lived near, would go and sit there for a few hours and after sunrise would trudge home, but whether or not there is any tradition or belief associated with the custom I have not ascertained. "How long has the custom existed?" I asked a field labourer. "From the time of the old people--the Druids," he answered, and I gave it up.
