《Byways Around San Francisco Bay》 - 免费有声读物

California, the land of sunshine and roses, with its genial climate, its skies as blue as the far-famed skies of Venice, and its pure, life-giving air, invites the lover of nature to take long tramps over hill and dale, mountain and valley, and to search out new trails in the rugged mountains. (Quote from section 2: Brook and Waterfall).
