The Masters of the Peaks (Illustrated) [EPUB ebook] 

A light wind sang through the foliage, turned to varying and vivid hues now by the touch of autumn, and it had an edge of cold that made Robert Lennox shiver a little, despite a hardy life in wilderness and open. But it was only a passing feeling. A moment or two later he forgot it, and, turning his eyes to the west, watched the vast terraces of blazing color piled one above another by the sinking sun.Often as he had seen it the wonderful late glow over the mighty forest never failed to stir him, and to make his pulse beat a little faster. His sensitive mind, akin in quality to that of a poet, responded with eagerness and joy to the beauty and majesty of nature. Forgetting danger and the great task they had set for themselves, he watched the banks of color, red and pink, salmon and blue, purple and yellow, shift and change, while in the very heart of the vast panorama the huge, red orb, too strong for human sight, glittered and flamed.
