The inconvenience and difficulty attending these interruptions, the breathless haste of the first part of their route, the exhausting sensations of hope and fear, so much affected the Countess's strength, that Janet was forced to propose that they should pause for a few minutes to recover breath and spirits.

Both therefore stood still beneath the shadow of a huge old gnarled oak-tree, and both naturally looked back to the mansion which they had left behind them, whose long, dark front was seen in the gloomy distance, with its huge stacks of chimneys, turrets, and clock-house, rising above the line of the roof, and definedly visible against the pure azure blue of the summer sky.

One light only twinkled from the extended and shadowy mass, and it was placed so low that it rather seemed to glimmer from the ground in front of the mansion than from one of the windows.

The Countess's terror was awakened.

"They follow us!" she said, pointing out to Janet the light which thus alarmed her.
Less agitated than her mistress, Janet perceived that the gleam was stationary, and informed the Countess, in a whisper, that the light proceeded from the solitary cell in which the alchemist pursued his occult experiments.
