On the top of an old wall covered with broad masses of lichen, the patches of which grew out at their edges as if a plate had taken to spreading at its rim, the tits were much occupied in picking out minute insects; the wagtails came too, sparrows, robins, hedge-sparrows, and occasionally a lark; a bare blank wall to all appearance, and the bare lichen as devoid of life to our eyes. Yet there must have been something there for all these eager bills--eggs or pupae. A jackdaw, with iron-grey patch on the back of his broad poll, dropped in my garden one morning, to the great alarm of the small birds, and made off with some large dark object in his beak--some beetle or shell probably, I could not distinguish which, and should most likely have passed the spot without seeing it. The sea-kale, which had been covered up carefully with seaweed, to blanch and to protect it from the frost, was attacked in the cold dry weather in a most furious manner by blackbirds, thrushes, and starlings. They tore away the seaweed with their strong bills, pitching it right and left behind them in as workmanlike style as any miner, and so boring deep notches into the edge of the bed. When a blackbird had made a good hole he came back to visit it at various times of the day, and kept a strict watch. If he found any other blackbird or thrush infringing on his diggings, he drove him away ferociously. Never were such works carried on as at the edge of that seaweed; they moved a bushel of it. To the eye there seemed nothing in it but here and there a small white worm; but they found plenty, and the weather being so bitter, I let them do much as they liked; I would rather feed than starve them. Down at the sea-shore in the sunny hours, out from the woodwork of the groynes or bulwarks, there came a white spotted spider, which must in some way have known the height to which the tide came at that season, because he was far below high-water mark. The moles in an upland field had made in the summer a perfect network of runs. Out of curiosity we opened some, and found in them large brown pupae. In the summer-house, under the wooden eaves, if you look, you will find the chrysalis of a butterfly, curiously slung aslant. Coming down Galley Hill, near Hastings, one day, a party was almost stopped by finding they could only walk on thousands of caterpillars, dark with bright yellow bands, which had sprung out of the grass. The great nettles--now, nothing is so common as a nettle--are sometimes festooned with a dark caterpillar, hundreds upon each plant, hanging like bunches of currants. Could you find a spot the size of your watch-seal without an insect or the germ of one?
