I drew a plan of the prison and grounds on paper, estimating as best I might all the possible checks we were like to meet with, and leaving a balance of chances in our favour that we could effect our purpose in a night. The priest leaned his chin upon his arms as he lolled over the table on which I eagerly explained my diagram, and sighed at one or two of the feats of agility it assumed. There was, for example, a roof to walk upon--the roof of the building we occupied--though how we were to get there in the first place was still to be decided. Also there was a descent from that roof on to the lower building at right angles, though where the ladder or rope for this was to come from I must meanwhile airily leave to fortune. Finally, there was--assuming we got into the larger building, and in some unforeseeable way along its roof and clear to the gable end--a part of the yard to cross, and the palisade to escalade. “Oh, lad! thou takest me for a bird,” cried his reverence, aghast at all this. “Is thy poor fellow prisoner a sparrow? A little after this I might do't with my own wings--the saints guide me!--but figure you that at present I am not Philetas, the dwarf, who had to wear leaden shoes lest the wind should blow him away. 'Twould take a wind indeed to stir this amplitude of good humours, this sepulchre of twenty thousand good dinners and incomputible tuns of liquid merriment. Pray, Paul, make an account of my physical infirmities, and mitigate thy transport of vaultings and soarings and leapings and divings, unless, indeed, thou meditatest sewing me up in a sheet, and dragging me through the realms of space.” “We shall manage! we shall manage!” I insisted, now quite uplifted in a fanciful occupation that was all to my tastes, even if nothing came of it, and I plunged more boldly into my plans. They were favoured by several circumstances--the first, namely, that we were not in the uniform of the prison, and, once outside the prison, could mingle with the world without attracting attention. Furthermore, by postponing the attempt till the morrow night I could communicate with the Swiss, and secure his cooperation outside in the matter of a horse or a vehicle, if the same were called for. I did not, however, say so much as that to his reverence, whom I did not wish as yet to know of my correspondence with Bernard. Finally, we had an auspicious fact at the outset of our attempt, inasmuch as the cell we were in was in the corridor next to that of which the sous-officer had some surveillance, and I knew his mind well enough now to feel sure he would help in anything that did not directly involve his own position and duties. In other words, he was to procure a copy of the key of our cell, and find a means of leaving it unlocked when the occasion arose.
