moment's consideration tells me that phosphate of lime No. 1 is touching phosphate of lime No. 2--nothing more. If for a moment I forget myself so far as to wave my cap and cheer for king, or queen, or prince, I laugh at my folly next moment for having paid reverence to one digesting machine above another." I cut the doctor short as he was lapsing into his favourite subject of discussion, and asked him whether he would lend me the pony-chaise on the following evening, that I might drive to the station again and try to unravel the mystery. "I will lend you the pony," said he, "but not the chaise, as I am afraid of its being injured should Taffy take fright and run up into the hedge again. I have got a saddle." Next evening I was on my way to the station considerably before the time at which the train was due. I stopped at the turnpike and chatted with the old man who kept it. I asked him whether he could throw any light on the matter which I was investigating. He shrugged his shoulders, saying that he "knowed nothink about it." "What! Nothing at all?" "I don't trouble my head with matters of this sort," was the reply. "People _do_ say that something out of the common sort passes along the road and turns down the other road leading to Clayton and Brighton; but I pays no attention to what them people says." "Do you ever hear anything?" "After the arrival of the 9.30 train I does at times hear the rattle as of a mail-cart and the trot of a horse along the road; and the sound is as though one of the wheels was loose. I've a been out many a time to take the toll; but, Lor' bless 'ee! them sperits--if sperits them be--don't go for to pay toll." "Have you never inquired into the matter?" "Why should I? Anythink as don't go for to pay toll don't concern me. Do ye think as I knows 'ow many people and dogs goes through this heer geatt in a day? Not I--them don't pay toll, so them's no odds to me." "Look here, my man!" said I. "Do you object to my putting the bar across the road, immediately on the arrival of the train?" "Not a bit! Please yersel'; but you han't got much time to lose, for theer comes thickey train out of Clayton tunnel." I shut the gate, mounted Taffy, and drew up across the road a little way below the turnpike. I heard the train arrive--I saw it puff off. At the same moment I distinctly heard a trap coming up the road, one of the wheels rattling as though it were loose. I repeat deliberately that I _heard_ it--I cannot account for it--but, though I heard it, yet I saw nothing whatever.
