"'It was that fellow Slurk; and he deserves a good horsewhipping for it!' replied Birchmore, thrusting his hands resolutely into his pockets. "'I think he deserves at least that,' I rejoined with a significant laugh; 'and whenever you're inclined to operate on him, I'll stand by you.' "Mr. Birchmore said no more, and we went downstairs in silence. Kate was already seated in the carriage; Slurk was on the box, with a large basket containing our provisions for the day beside him. Mr. Birchmore and I took our places--one of us at least with a heavy heart. The landlord stood at the door and nodded us a surly farewell. "'Where is Christina?' I asked him. "'She has gone to the town to sell eggs: did the Herr want anything?' "'I should like to have sent for a screwdriver; but probably I can get one on our way back,' was my answer; and with that we drove away. "In about half an hour, proceeding by unfrequented roads, we came in sight of Kohlstein. It was a vast four-sided mass of gray rock, seamed with deep clefts and fissures running horizontally and vertically, so that it appeared to have been built of gigantic blocks of stone. It was considerably over one hundred feet in sheer height, and it stood upon a rising ground of shifting sand. Slender trees grew here and there out of the crevices of its headlong sides, and straggled nakedly along its level summit, outlined against the sky. It was an ideal place for a robber stronghold; impregnable, certainly, to any attack save that of the heaviest modern artillery. "'We must get out and walk from here,' remarked Mr. Birchmore. 'There's only one way of getting to the top, and that's on the other side. I have got a touch of my rheumatics to-day, and hardly think I shall be able to do the climbing. However, that needn't interfere with you young people, of course.' "I exchanged a covert look with Kate as I helped her to descend from the carriage; and she pressed my hand and smiled. I admired her courage as much as I lamented the apparent lack of it in her father. The horse having been unharnessed and tethered where some cool grass grew beside a stream, we struck off across the sandy upland; Slurk carrying the big basket, Mr. Birchmore walking with a rather feeble step near him, and Kate and I in front. It was an even hotter day than yesterday, and the tramp was a wearisome one. By the time we arrived at the foot of the Stein, we were quite ready to rest a few minutes in the shadow of the rock, for coolness and breath. "'No, I can't do it!' said Mr. Birchmore, wiping his forehead and glancing hopelessly up at the narrow white footpath that seemed to mount almost straight upward to the distant summit. 'Just leave me here, with a few sandwiches and a bottle of hock, and I shall do very comfortably till you come back.'
