Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Mountaineers will realize, from these descriptions of Sierra climbs, how few dangers we encountered which might not have been avoided by time and cau tion. Since the uncertain perils of glacier work and snow copings do not exist in California, except on the northeast flank of Mount Shasta, our climbs proved safe and easy in comparison with the more serious Alpine ascents. And now that the topography of the higher Sierra has been all explored by the Geolog ical Survey, nearly every peak is found to have an accessible side. Our difficulties and our joys were those of the pioneer.
