Neither is it easy to understand how these amateurs contrived to do so much without a catastrophe. To make a tunnel through soft earth is a very delicate operation, replete with unlooked-for difficulties. To shore up the roof and sides there must, moreover, have been required a large quantity of the "framed timber" of which Speed tells us, and the provision and importation of this must have been almost as hard to keep dark as the exportation of the earth and stones. A still more critical operation is that of meddling with the foundations of a house--especially of an old and heavy structure--which a professional craftsman would not venture upon except with extreme care, and the employment of many precautions of which these light-hearted adventurers knew nothing. Yet, recklessly breaking their way out of one building, and to a large extent into another, they appear to have occasioned neither crack nor settlement in either. We are by no means at the end of our difficulties. According to the tale told by Faukes,[151] all the seven miners "lay in Percy's house," never showing themselves while the work was in progress. This circumstance, to say nothing of the storage of powder barrels and timber, seems to imply that the premises were spacious and commodious. We learn, however, on the unimpeachable evidence of Mrs. Whynniard's servant,[152] that the house afforded accommodation only for one person at a time, so that when Percy came there to spend the night, Faukes, who passed for his man, had to lodge out. This suggests another question. Percy's pretext for laying in so much fuel was that he meant to bring up his wife to live there. But how could this be under such conditions?
