This same nightingale was keeping a little surprise in store for me. Although he took no notice of me sitting at the open window, whenever I went thirty or forty yards from the gate along the narrow lane that faced it, my presence troubled him and his mate only too much. They would flit round my head, emitting the two strongly contrasted sounds with which they express solicitude--the clear, thin, plaintive, or wailing note, and the low, jarring sound--an alternate lamenting and girding. One day when I approached the nest, they displayed more anxiety than usual, fluttering close to me, wailing and croaking more vehemently than ever, when all at once the male, at the height of his excitement, burst into singing. Half a dozen notes were uttered rapidly, with great strength, then a small complaining cry again, and at intervals, a fresh burst of melody. I have remarked the same thing in other singing birds, species in which the harsh grating or piercing sounds that properly express violent emotions of a painful kind, have been nearly or quite lost. In the nightingale, this part of the bird's language has lost its original character, and has dwindled to something very small. Solicitude, fear, anger, are expressed with sounds that are mere lispings compared with those emitted by the bird when singing. It is worthy of remark that some of the most highly developed melodists--and I am now thinking of the mocking-birds--never, in-moments of extreme agitation, fall into this confusion and use singing notes that express agreeable emotions, to express such as are painful. But in the mocking-bird the primitive harsh and grating cries have not been lost nor softened to sounds hardly to be distinguished from those that are emitted by way of song. III By this time all the birds were breeding, some already breeding a second time. And now I began to suspect that they were not quite so undisturbed as the old dame had led me to believe; that they had not found a paradise in the village after all. One morning, as I moved softly along the hedge in my nightingale's lane, all at once I heard, in the old grassy orchard, to which it formed a boundary, swishing sounds of scuttling feet and half-suppressed exclamations of alarm; then a crushing through the hedge, and out, almost at my feet, rushed and leaped and tumbled half-a-dozen urchins, who had suddenly been frightened from a bird-nesting raid. Clothes torn, hands and faces scratched with thorns, hat-less, their tow-coloured hair all disordered or standing up like a white crest above their brown faces, rounded eyes staring--what an extraordinarily wild appearance they had! I was back in very old times, in the Britain of a thousand years before the coming of the Romans, and these were her young barbarians, learning their life's business in little things.
