Fortunately, a rattlesnake will usually give warning of his belligerent intent before beginning hostile operations, and he prefers blissful solitude to the so- ciety of those who never neglect an opportunity to bruise his head. Never- theless, while in the lava fields, the writer learned, after several narrow es- capes, to examine a rock rather care- fully from a biological point of view before examining it geologically or be- fore sitting down on it to rest. The snake is especially peevish about his sun bath, and the man who disturbs his slumbers by sitting down too near him is very likely to rise again without his desired rest. HORSESHOE MOUNTAIN Horseshoe Mountain is the crater cone of an extinct volcano consisting at the surface entirely of scoriaceous cinders. It is nearly circular in outline and the rim of the crater is broken down on one side, giving to the crest the general form of a horseshoe. The cone rests on a broad platform of flow lava that is relatively old. Its surface is rolling, and it is covered with soil, but the cinder cone is very young. Al- though it is composed of loose or slightly consolidated material that washes down in considerable quantities with every rain, giving the surface a corrugated appearance, the sides are still nearly as steep as it is possible for them to be with loose material, and the absence of large accumulations of cin- ders at the base that can be attributed to wash from its slopes indicates that the cone still retains essentially the form that the extr
