It is a marvel how the birds contrive to survive in this world. These tender sparrows that flit from bush to bush this evening, though it is so late, do not seem improvident, [but appear] to have found a roost for the night. They must succeed by weakness and reliance, for they are not bold and enterprising, as their mode of life would seem to require, but very weak and tender creatures. I have seen a little chipping sparrow, come too early in the spring, shivering on an apple twig, drawing in its head and striving to warm it in its muffled feathers; and it had no voice to intercede with nature, but peeped as helpless as an infant, and was ready to yield up its spirit and die without any effort. And yet this was no new spring in the revolution of the seasons.
