Clear Lake and the Blue Lakes in Lake County are delightful places to visit, and in this county, too, are the geysers. Some wonderful curiosities are seen here. You will find springs that spout up a stream of hot water every few minutes, mineral springs from which you can have a drink of soda water, and an acid spring that flows lemonade. Alum, iron, or sulphur waters, either hot or cold, bubble up out of the ground at every turn. At one spring you may boil an egg. Other springs are used for steam baths and also hot mud-baths. In Geyser Cañon is the strange place every sight-seer hurries to at once. Such rumblings and thunderings, such hot vapors and gases come from the cracks in the ground, that the Indians thought this was the workshop where the bad spirit which white people call the devil used to live and work. The deeper one goes into this cañon, the hotter and noisier it gets. All round are signs telling where it is dangerous to step, while the ground is hot, and boiling water runs by in little streams. Steam rises from many pools, and the sulphur smell almost chokes one. Another curious spring, called the devil's inkstand, seems full of ink. Mount St. Helena, near here, is a dead or extinct volcano, and probably there are fires in the earth under this region which keep up these steam and sulphur springs. [Illustration: NATURAL BRIDGE, SANTA CRUZ.] Many of the Sierra summits are capped with volcanic rock, and Lassen's Peak and Mount Shasta are extinct volcanoes. There are hot springs and cracks from which steam and sulphur rise on both of these mountains, and as earthquakes often shake the earth in different parts of the state we know that underground fires are still at work. A great piece of land on Mount San Jacinto in Southern California lately sank down about a hundred feet, and cracks both deep and wide show that some force from below gave a thorough shaking-up to that part of the state. Mono, Owen's, and several other large lakes are the "sinks" into which rivers flow and lose themselves in the sandy or marshy shores. These lakes have soda or salt in their waters, and great stretches of dry alkali lands around them. The famous Death Valley is a dry lake of this kind where the sun beats down on the white alkali plain till it is almost certain death to try to cross it without a guide. The Salton Sea is a dry lake where almost pure salt is dug out, and great quantities of borax and of soda are found in other beds, of dried-up streams and lakes. But to tell of all the curious things nature has to show us in California,--of the forests of petrified trees, of the caverns cut out of the ocean cliffs by restless waves, or of those in the mountains or the Modoc lava-beds,--well, you will see most of them, let us hope, in your vacations. A large book might be given to the wonderful sights of this great state, and it may be your fortune to visit and so always remember a few we have named. PRONOUNCING VOCABULARY
