The sledge had reached the other slope of the mountain and darted like an arrow through the darkness. The tramp of the horse's hoofs, the hard-drawn breath of the escort, and from time to time the call of the doctor, "Ho, Bruno, old fellow!" alone broke the deep stillness.
A rush of ice-cold air, rolling up from the valley of the Sarre, bore from afar, like a sigh, the never-ending plaint of the torrents and woods. The moon broke through a cloud and looked down on the dark forests of Blanru, with their tall, snow-laden firs. A few moments after, the sledge reached a corner of the woods, and Doctor Lorquin, turning in his saddle, cried:
"Now, Frantz, what are we to do? The path turns to the hills of Saint-Quirin, and here is another going down to Blanru. Which shall we take?"
Frantz and the men of the escort drew near. As they were then on the western side of the Donon, they began to catch glimpses once more of the German fusilade, and occasionally they heard the crash of a cannon-shot echo through the abysses. "The path to the hills of Saint-Quirin," replied Frantz, "is shorter if we wish to stop at Bois-de-Chênes; we shall gain at least three quarters of an hour by it."
"Yes," said the doctor, "but we risk being taken by the Kaiserliks who now hold the defile of the Sarre. They are already masters of the heights, and they have doubtless sent detachments to the Sarre-Ridge in order to turn Donon."
"Let us, take the Blanru path then," answered Frantz; "it is longer, but safer."
The sledge descended the mountain side to the left, along the skirts of the wood. The partisans in single file, their rifles slung on their backs, marched upon the top of the slope, and the doctor, on horseback, in the narrow way, broke through the snowdrifts. Above hung the long fir branches, burying road and travellers in deep shadow, beyond which streamed the pale moonlight. The scene was picturesque and majestic, and under other circumstances Catherine would have wondered at its weird beauty, and Louise would not have failed to admire the long icicles glittering like spars of crystal where the moonbeams fell; but now their hearts were full of unrest and fear, and soon the sledge entered the deep gorge, whence they could see no light but that which flooded the mountain peaks. Thus they pushed on in silence until at length Catherine, rousing herself from the gloomy thoughts in which she seemed plunged, spoke.
"Doctor Lorquin, now that you have us at the bottom of Blanru, will you explain why we have thus been carried off? Jean-Claude seized me, threw me on this truss of straw, and here I am."
"Ho, Bruno!" cried the doctor.
