The prickly pear in its desert home.
While we cannot stop the water falling from the clouds, we can drain the lowlands and marshes and so make them fit for the farmer. We can raise great dikes or embankments along the rivers and so shut out the flood waters. The people of Holland have saved thousands of acres from the sea by building dikes and pumping out the water from the inclosed fields.
While we cannot make it rain where not enough rain falls, we can do that which is just as good or better: we can carry water by ditches and pipes to the land that needs it. Much of the soil of the great deserts in the southwestern part of our country is rich in plant food. All that it lacks is water.
The Indian roamed over the rich lands of the great delta of the Colorado River. He often went hungry and thirsty. He did not think of taking the water out of the river in a ditch and allowing it to flow over and wet the rich soil. The white man came and turned the river out of its channel and spread the water over hundreds of square miles of the richest land on the earth. Now, where once you would have died of thirst and hunger, there are green fields and growing crops as far as you can see.
The Owens River aqueduct, through which water is carried to Los Angeles from a source more than two hundred miles distant.
The city of Los Angeles is situated in a dry region where there is not water enough for the needs of a great city. There has now been completed a great aqueduct which brings a river of water through deserts and mountains from the Sierra Nevada Mountains, over two hundred miles away. There is now sufficient water for hundreds of thousands of people.
When it rains too much, many rivers rise and overflow their banks. The farmer's crops are destroyed, his cattle drowned, and his buildings washed away. We can lessen the danger from these floods, which are very bad in such river basins as those of the Ohio and Mississippi, by building reservoirs in the highlands where the rivers take their start. If when summer comes these rivers are too shallow for safe navigation, the reservoirs can be opened and the streams supplied with this stored water.
