After a late breakfast I sallied out again, going farther in the same direction, and was overtaken by several showers. I heard many and frequent bird-songs,--the lark, the wren, the thrush, the blackbird, the whitethroat, the greenfinch, and the hoarse, guttural cooing of the wood-pigeons,--but not the note I was in quest of. I passed up a road that was a deep trench in the side of a hill overgrown with low beeches. The roots of the trees formed a network on the side of the bank, as their branches did above. In a framework of roots, within reach of my hand, I spied a wren's nest, a round hole leading to the interior of a large mass of soft green moss, a structure displaying the taste and neatness of the daintiest of bird architects, and the depth and warmth and snugness of the most ingenious mouse habitation. While lingering here, a young countryman came along whom I engaged in conversation. No, he had not heard the nightingale for a few days; but the previous week he had been in camp with the militia near Guildford, and while on picket duty had heard her nearly all night. "'Don't she sing splendid to-night?' the boys would say." This was tantalizing; Guildford was within easy reach; but the previous week,--that could not be reached. However, he encouraged me by saying he did not think they were done singing yet, as he had often heard them during haying-time. I inquired for the blackcap, but saw he did not know this bird, and thought I referred to a species of tomtit, which also has a black cap. The woodlark I was also on the lookout for, but he did not know this bird either, and during my various rambles in England I found but one person who did. In Scotland it was confounded with the titlark or pipit. I next met a man and boy, a villager with a stove-pipe hat on,--and, as it turned out, a man of many trades, tailor, barber, painter, etc.,--from Hazlemere. The absorbing inquiry was put to him also. No, not that day, but a few mornings before he had. But he could easily call one out, if there were any about, as he could imitate them. Plucking a spear of grass, he adjusted it behind his teeth and startled me with the shrill, rapid notes he poured forth. I at once recognized its resemblance to the descriptions I had read of the opening part of the nightingale song,--what is called the "challenge." The boy said, and he himself averred, that it was an exact imitation. The _chew, chew, chew_, and some other parts, were very bird-like, and I had no doubt were correct. I was astonished at the strong, piercing quality of the strain. It echoed in the woods and copses about, but, though oft repeated, brought forth no response. With this man I made an engagement to take a walk that evening at eight o'clock along a certain route where he had heard plenty of nightingales but a few days before. He was confident he could call them out; so was I.
