Midsummer Bonfires.
Our bonfires, torches, and tar-barrels, with the peculiar hand-in-hand dance around the blazing piles, remind us of ancient times when similar customs were regarded as sacred rites by our forefathers; and it would seem a s if some vestiges of these time-honoured religious notions were still connected with Midsummer bonfires in the minds of old-fashioned people, living in remote and primitive districts, where they still believe that dancing in a ring over the embers, around a bonfire, or leaping (singly) through its flames, is calculated to insure good luck to the performers and to serve as a protection from witchcraft and other malign influences during the ensuing year.
Many years ago, on Midsummer's eve, when it became dusk, very old people in the West Country would hobble away to some high ground, whence they obtained a view of the most prominent hills, such as Bartinney, Chapel Carn-brea, Sancras Bickan, Castle-an-Dinas, Carn Galver, St. Agnes Bickan, and many other beacon hills far away to north and east, which vied with each other in their Midsummer's blaze. They counted the fires and drew a presage from the number of them. There are now but few bonfires to be seen on the western heights; yet we have observed that Tregonan, Godolphin, and Carn Marth hills, with others away towards Redruth, still retain their Baal fires. We would gladly go many miles to see the wierd-looking, yet picturesque, dancers around the flames on a cam, or high hill top, as we have seen them some forty years ago.
We are sorry to find that another pleasing Midsummer's observance, which also appears to be ancient, has almost died out. Yet within the memory of many, who would not like to be called old or even aged, on a Midsummer's eve long before sunset, groups of girls—both gentle and simple—of from ten to twenty years of age, neatly dressed and decked with garlands, wreaths, or chaplets of flowers, would be seen dancing in the streets.
One favourite mode of adornment was to sew, or pin, on the skirt of a white dress, rows of laurel-leaves, often spangled with gold leaf. Before Midsummer small wooden hoops were in great demand to be wreathed with green boughs and flowed for garlands, to be worn over one shoulder and under the opposite arm. Towards sunset groups of graceful damsels, joined by their brothers, friends, or lovers, would be seen "threading-the-needle," playing at "kiss-in-the-ring," or simply dancing along every here and there from Chyandour to Alverton, from the Quay to Caunsehead, as the upper part of the town used then to be called, perhaps with more propriety than Causewayhead.
