the strange word with a curious sensation of
pleasure. "There is something mysteriously suggestive about the sound of
it; like a chord of music played softly in the distance. Now, can I get
through this door, I wonder?"

He pushed it gently. It yielded very slightly, and he tried again and
yet again. Finally, he put down the lamp and set his shoulder against
the wooden barrier with all his force. A dull creaking sound rewarded
his efforts, and inch by inch the huge door opened into what at first
appeared immeasurable darkness. Holding up the light he looked in, and
uttered a smothered exclamation. A sudden gust of wind rushed from the

Sir Philip walked along very slowly, delighted with his discovery,
and,--pausing to examine each panel as he passed,--amused himself with
speculations as to the meaning of this beautiful cavern, so fancifully
yet skillfully decorated.

"Some old place of worship, I suppose," he thought. "There must be many
such hidden in different parts of Norway. It has nothing to do with the
Christian faith, for among all
