As in so many other cases, English- speaking people have used a Latin word to make an English word. All rock which has hardened from hot molten matter is called igneous rock. One common kind of igneous rock is granite. It is composed of crystals of three or four different minerals, which can plainly be seen. Granite is a very hard rock, and is often left standing 126 WATER AND HOW WE USE IT as a mountain-peak, from which the softer rocks have been worn away. It is very common in New England. An...other class of igneous rock has been formed by volcanic action. Even now some volcanoes occasionally send out great rivers of molten lava which hardens into rock. In ages past vol- canoes have been much more active than they are now. In some parts of the world great lava floods have flowed out from cracks in the earth's surface. The Palisades of the Hudson, the hills of New Jersey and of the Connecticut Valley, parts of Yellow- stone Park, and the Snake River and Columbia River Valleys, in Washington, Oregon, and Idaho, are a few of the places in our own country composed of hard- ened lava.
