and only the thought of tomorrow persuaded us to turn in. A tent with double blanket on yielding, fragrant boughs seemed luxurious. We fastened the lower flap to keep out the porcupines who have a playful habit of chewing footgear and driving, the quill, to one's dismay, when interfered with.
After a restful sleep, which you often fail to get in city turmoil, we arose as Aurora, rosy-fingered dawn, was tinting the rocks and glaciers in soft morning light.
