If you dip up a gallon of water, you will get about fifteen thousand of these. They give to the water a sort of grayish-white appearance. Then there is a fly, which looks something like our house fly. If you throw a stone among them, they swarm up so thick that they look dense, like a cloud. When you let them go, they pop up to the surface as dry as a patent office report, and walk off as unconcernedly as if they had been educated especially with a view to affording instructive entertainment to man in that particular way.
Providence leaves nothing to go by chance.
All things have their uses and their part and proper place in Nature's economy. One would as soon expect to find sea-gulls in Tennessee. And in this connection let us observe another instance of Nature's wisdom. Within ten feet of the boiling spring is a spring of pure cold water, sweet and wholesome. Half a dozen little mountain brooks flow into Mono Lake, but not a stream of any kind flows out of it.
