In the autumn of 1651, when King Charles was stealing along from Colonel Wyndham’s house to the coast of Hampshire and Sussex, the little band was overtaken by nightfall, somewhere near the New Forest. It was shortly after the narrow escape of the King from that observant blacksmith, who saw that his horse was shod with North-country iron. Though he was taking it easily, his three trusty friends knew well that a Roundhead Squadron was near, and that his last chance depended on speed and night travel. What could they do now in the tempestuous darkness? They were in a tract thinly inhabited, half woodland, half heather, and the road was hopelessly lost. No rain fell as yet it was true, and the wind was waiting for rain, but the lightning came fitfully from the horizon all round. The King alone was on horseback, his three companions afoot. They stood still in doubt and terror, for they could not tell north from south. Suddenly Major Cecil Vaughan espied a faint gleam familiar to him of old in the waste land round Vaughan Park. To an accurate eye there could be little doubt as to the source of the lambent light--flame it could not be called. It played in a pale yet constant stream on a certain kind of moss, known to botanists, not to me, for the waste lands have been reclaimed. This light is to be seen at no time, except when the air is surcharged with electricity. "Follow me all; I know the way!" cried Major Vaughan, right cheerily. "And if you do, man," said the King, "your eyes are made of dashers." [What this meant, I used as a child to wonder; but now I know.] For six dark miles the Major led them without default, until they came to a lonely heathman’s house, where they slept in safety. He never told them how he did it; being apt, I suppose, as men of the second order are, to hug superior knowledge. But it was a most simple thing. That strangely sensitive moss follows the course of the sun, and therefore the lambent light can only be seen from the west. So all the time he could see it--the others never saw it at all--he knew that they were wending from west to east, which was their proper course.
