The precautions taken by the conspirators did not render their task easier. It was in the second fortnight, beginning after the middle of January, when the hard work of getting through the strong and broad foundation of the House of Lords tried their muscles and their patience, that they swore in Christopher Wright, and brought over Keyes from Lambeth together with the powder which they now stored in 'a low room new-builded.'[169] After a fortnight's work, reaching to Candlemas (Feb. 2), they had burrowed through about four feet six inches into the wall, after which they again gave over working.[170] Some time in the latter part of March they returned to their operations, but they had scarcely commenced when they found out that it would be possible for them to gain possession of a locality more suited to their wants, and they therefore abandoned the project of the mine as no longer necessary.[171] Before passing from the story of the mine, the more important of Father Gerard's criticisms require an answer. How, he asks, could the conspirators have got rid of such a mass of earth and stones without exciting attention?[172] Fawkes, indeed, says that 'the day before Christmas having a mass of earth that came out of the mine, they carried it into the garden of the said house.' Then Goodman declares that he saw it,[173] but, even if we assume that his memory did not play him false, it is impossible that the whole of the produce of the first fortnight's diggings should be disposed of in this way. The shortest length that can be ascribed to the mine before the wall was reached is eight feet, and if we allow five feet for height and depth we have 200 cubical feet, or a mass more than six feet every way, besides the stones coming out of the wall after Christmas. Some of the earth may have been, as Fawkes said, spread over the garden beds, but the greater part of it must have been disposed of in some other way. Is it so very difficult to surmise what that was? The nights were long and dark, and the river was very close.
