I drink at every cooler spring in my walk these afternoons and love to eye the bottom there, with its pebbly caddis-cases, or its white worms, or perchance a luxurious frog cooling himself next my nose.
Sometimes the farmer, foreseeing haying, has been prudent enough to sink a tub in one, which secures a clear deep space. It would be worth the while, methinks, to make a map of the town with all the good springs on it, indicating whether they were cool, perennial, copious, pleasantly located, etc. The farmer is wont to celebrate the virtues of some one on his own farm above all others. Some cool rills in the meadows should be remembered also, for some such in deep, cold, grassy meadows are as cold as springs. I have sometimes drank warm or foul water, not knowing such cold streams were at hand. By many a spring I know where to look for the dipper or glass which some mower has left. When a spring has been allowed to fill up, to be muddied by cattle, or, being exposed to the sun by cutting down the trees and bushes, to dry up, it affects me sadly, like an institution going to decay.
Sometimes I see, on one side the tub, – the tub overhung with various wild plants and flowers, its edge almost completely concealed even from the searching eye, – the white sand freshly cast up where the spring is bubbling in. Often I sit patiently by the spring I have cleaned out and deepened with my hands, and see the foul water rapidly dissipated like a curling vapor and giving place to the cool and clear. Sometimes I can look a yard or more into a crevice under a rock, toward the sources of a spring in a hillside, and see it come cool and copious with incessant murmuring down to the light. There are few more refreshing sights in hot weather.
