A row of tall trees ran along at each side of the road, and nearly met at top, and the fitful breeze just agitating the leaves, or occasionally moving the branches so as to cause a low, moaning, creaking noise, jarred my nerves, and made me feel still more and more unpleasant. At length, when I had arrived at an intolerable pitch of nervous excitement, the darkness became less intense, and I could just distinguish a breach in the row of trees upon the right, which marked the locality of the 'laght.' Taking advantage of the opportunity, I pressed my horse. He seemed to have become as nervous as myself, for he answered to the slight touch of the spur with a loud snort and a violent spring, which I considered so totally uncalled for, as to give me a very fair excuse for being in a passion, and venting my irritability, which I proceeded to do with my whip, as giving my muscles more action than the spur; but instead of plunging along at a mad gallop, as I expected, my horse reared, and turning sharply round, attempted a flight back. Again and again I turned his head to the road, but onward he would not go; this was very strange, for he never shied or started. At length I tried the soothing system; for I must confess that the general belief that horses see what is hidden from the eyes of man, occurred to me, and I coaxed and patted him, and spoke gently and encouragingly to him, but he kept sidling, and tramping, attempting to turn, and answering every word or pat with a long snore, whilst I could perceive by his forward pricked ears and the direction of his head, that his eyes were rivetted upon the heap of stones. Whilst thus engaged, and having somewhat quieted his terror, I heard a sound like the rattling of chains. Round and away with Rainbow. I brought him up again nearer than before. Again the chains clanked, and I could distinctly hear that they were chains, ere my horse bolted and ran again. 'The third time,' said I, 'contains a charm, they say; and, man or devil, ghost or fairy, I'll overhaul you. Who's there?' No answer. 'Who's there?' Clank, clank, went the chains. I could see nothing. The perspiration was running down my face, but I was furious. 'By the hand of my grandfather, if you do not answer me, I'll go to you, and whilst sinew and whalebone last, you shall feel the butt of a loaded whip. Who are you?' Again the chains clanked, and my horse would not consent to keep such company any longer. I dismounted, and, taking him a few paces back, tied him to a tree, and returned on foot to the spot.
