[Original]
While Halbert Glendinning gazed from the window with that eagerness of hope which was prompted by the energy of his character and his determination not to yield to circumstances, his ear caught some sounds from below, and listening with more attention, he could distinguish the voice of the preacher engaged in his solitary devotions. To open a correspondence with him became immediately his object, and failing to do so by less marked sounds, he at length ventured to speak, and was answered from beneath—“Is it thou, my son?” The voice of the prisoner now sounded more distinctly than when it was first heard, for Warden had approached the small aperture, which, serving his prison for a window, opened just betwixt the wall and the rock, and admitted a scanty portion of light through a wall of immense thickness. This soupirait being placed exactly under Halbert's window, the contiguity permitted the prisoners to converse in a low tone, when Halbert declared his intention to escape, and the possibility he saw of achieving his purpose, but for the iron stanchions of the window—“Prove thy strength, my son, in the name of God” said the preacher. Halbert obeyed him more in despair than hope, but to his great astonishment, and somewhat to his terror, the bar parted asunder near the bottom, and the longer part being easily bent outwards, and not secured with lead in the upper socket, dropt out into Halbert's hand. He immediately whispered, but as energetically as a whisper could be expressed—“By Heaven, the bar has given way in my hand!”
“Thank Heaven, my son, instead of swearing by it,” answered Warden from his dungeon.
With little effort Halbert Glendinning forced himself through the opening thus wonderfully effected, and using his leathern sword-belt as a rope to assist him, let himself safely drop on the shelf of rock upon which the preacher's window opened. But through this no passage could be effected, being scarce larger than a loop-hole for musketry, and apparently constructed for that purpose.
“Are there no means by which I can assist your escape, my father?” said Halbert.
“There are none, my son,” answered the preacher; “but if thou wilt ensure my safety, that may be in thy power.”
“I will labour earnestly for it,” said the youth.
“Take then a letter which I will presently write, for I have the means of light and writing materials in my scrip—Hasten towards Edinburgh, and on the way thou wilt meet a body of horse marching southwards—Give this to their leader, and acquaint him of the state in which thou hast left me. It may hap that thy doing so will advantage thyself.”
In a minute or two the light of a taper gleamed through the shot-hole, and very shortly after, the preacher, with the assistance of his staff, pushed a billet to Glendinning through the window.
