We are further asked to explain how it was that, if there was really a mine, the Government did not find it out for some days after the arrest of Fawkes. Why should they? The only point at which it was accessible was at its entrance in Percy's own cellar, and it is an insult to the sharp wits of the plotters, to suppose that they did not close it up as soon as the project of the mine was abandoned. All that would be needed, if the head of the mine descended, as it probably did, would be the relaying of a couple or so of flagstones. How careful the plotters were of wiping out all traces of their work, is shown by the evidence of Whynniard's servant, Roger James, who says that about Midsummer 1605, Percy, appearing to pay his quarter's rent, 'agreed with one York, a carpenter in Westminster, for the repairing of his lodging,' adding 'that he would send his man to pay the carpenter for the work he was to do.'[174] Either the mine had no existence, or all traces of it must have been effectually removed before a carpenter was allowed to range the house in the absence of both Percy and Fawkes. I must leave it to my readers to decide which alternative they prefer. According to the usually received story, the conspirators, hearing a rustling above their heads, imagined that their enterprise had been discovered, but having sent Fawkes to ascertain the cause of the noise, they learnt that Mrs. Skinner (afterwards Mrs. Bright) was selling coals, and having also ascertained that she was willing to give up her tenancy to them for a consideration, they applied to Whynniard--from whom the so-called 'cellar' was leased through his wife, and obtained a transfer of the premises to Percy. All that remained was to convey the powder from the house to the 'cellar,' and after covering it with billets and faggots, to wait quietly till Parliament met. Father Gerard's first objection to this is, that whilst they were mining, 'ridiculous as is the supposition, the conspirators appear to have been ignorant of the existence of the "cellar," and to have fancied that they were working their way immediately beneath the Chamber of Peers.' The supposition would be ridiculous enough if it were not a figment of Father Gerard's own brain. He relies on what he calls 'Barlow's Gunpowder Treason,'[175] published in 1678, and on a remark made by Tierney in 1841, adding that it is 'obviously implied' by Fawkes and Winter. What Fawkes says on November 17 is:-- "As they were working upon the wall, they heard a rushing in a cellar of removing of coals; whereupon we feared we had been discovered, and they sent me to go to the cellar, who finding that the coals were a selling, and that the cellar was to be let, viewing the commodity thereof for our purpose, Percy went and hired the same for yearly rent."[176]
