Orwell on Spring

From "Some Thoughts on the Common Toad":

Before the swallow, before the daffodil, and not much later than the snowdrop, the common toad salutes the coming of spring after his own fashion, which is to emerge from a hole in the ground, where he has lain bruied since the previous autumn, and crawl as rapidly as possible towards the nearest suitable patch of water. Something--some kind of shudder in the earth, or perhaps merely a rise of a few degrees in the temperature--has told him that it is time to wake up.
