coach No doubt

"No doubt, Jack," answered Harry. "It remains to be seen whether this being was as supernatural as you choose to believe."
"Supernatural!" exclaimed Ryan. "But it was as supernatural as a Will-o'-the-Wisp, who may be seen skipping along with his lantern in his hand; you may try to catch him, but he escapes like a fairy, and vanishes like a shadow! Don't be uneasy, Harry, we shall see it again some day or other!"
"Well, Jack," said Simon Ford, "Will-o'-the-Wisp or not, we shall try to find it, and you must help us."
"You'll get into a scrap if you don't take care, Mr. Ford!" responded Jack Ryan.
"We'll see about that, Jack!"
We may easily imagine how soon this domain of New Aberfoyle became familiar to all the members of the Ford family, but more particularly to Harry. He learnt to know all its most secret ins and outs. He could even say what point of the surface corresponded with what point of the mine. He knew that above this seam lay the Firth of Clyde, that there extended Loch Lomond and Loch Katrine. Those columns supported a spur of the Grampian mountains. This vault served as a basement to Dumbarton. Above this large pond passed the Balloch railway. Here ended the Scottish coast. There began the sea, the tumult of which could be distinctly heard during the equinoctial gales. Harry would have been a first-rate guide to these natural catacombs, and all that Alpine guides do on their snowy peaks in daylight he could have done in the dark mine by the wonderful power of instinct.
He loved New Aberfoyle. Many times, with his lamp stuck in his hat, did he penetrate its furthest depths. He explored its ponds in a skillfully-managed canoe. He even went shooting, for numerous birds had been introduced into the crypt--pintails, snipes, ducks, who fed on the fish which swarmed in the deep waters. Harry's eyes seemed made for the dark, just as a sailor's are made for distances. But all this while Harry felt irresistibly animated by the hope of finding the mysterious being whose intervention, strictly speaking, had saved himself and his friends. Would he succeed? He certainly would, if presentiments were to be trusted; but certainly not, if he judged by the success which had as yet attended his researches.
The attacks directed against the family of the old overman, before the discovery of New Aberfoyle, had not been renewed.
Chapter 11 Hanging By A Thread
ALTHOUGH in this way the Ford family led a happy and contented life, yet it was easy to see that Harry, naturally of a grave disposition, became more and more quiet and reserved. Even Jack Ryan, with all his good humor and usually infectious merriment, failed to rouse him to gayety of manner.
One Sunday--it was in the month of June--the two friends were walking together on the shores of Loch Malcolm. Coal Town rested from labor. In the world above, stormy weather prevailed. Violent rains fell, and dull sultry vapors brooded over the earth; the atmosphere was most oppressive.
Down in Coal Town there was perfect calm; no wind, no rain. A soft and pleasant temperature existed instead of the strife of the elements which raged without. What wonder then, that excursionists from Stirling came in considerable numbers to enjoy the calm fresh air in the recesses of the mine?
