I have received from a friend in Northamptonshire (Mr. G. S. Garrett, of Little Houghton) a photograph showing a similar instance of two nests built one above the other. He says: "A piece of bark about 20 inches by 13, fell off an elm tree into a fence and dried up into a tube-like shape. A spotted flycatcher built its nest in the top and laid 5 eggs and a brown wren in the bottom laying 7 eggs.... The nests are now in the Rochester Museum." X. BRITISH MAMMALS. The whole extent of the garden, with its croft and orchard, is not three acres, but a fair proportion of the British mammals are from time to time to be found there. The old church, largely built of timber, picturesque and quaint, stands within a few yards of the house and its roof affords shelter to many bats. We find the wings of moths, the remnants of their feasts, scattered on the floor (I have noticed the wings of a tortoise-shell butterfly among them), and I have found there more than one dead body of a common bat; I cannot say whether that is the only kind we have, but in 1908 a bat was seen near the house which, from the description given of its size and manner of flight, may perhaps have been a noctule. On May 28th, 1899, there was an eclipse of the sun; it was only partial, and made very little difference to the light, but just so long as it lasted, from 3 to 4.30 p.m., I saw a bat flying busily round and about the church. The soil is light and worms seem to be abundant, but one hardly ever sees a mole-hill in this part of Cheshire. One day, however, in December, 1899, we noticed that a bed of parsley had withered in a mysterious way, and when we came to look, the ground was quite undermined with mole-runs. These were very shallow, and there was no sign of a hillock above. Many of the roots of the parsley had been entirely eaten off, and we saw that nearly all that remained in the bed were full of grubs. These grubs it must have been, I suppose, that attracted the mole, but it is curious that such an exceptional condition of the roots should have been discovered, considering how seldom there is any sign of a mole in the neighbourhood. We noticed that the root of a strong raspberry cane on one side of the parsley bed had been eaten off in the same way, but it is not very likely that this would have had grubs in it. Hedgehogs are not uncommon and we sometimes see them in broad daylight. In July one year (1900) every evening for about a week we used to see a large hedgehog running along a broad gravel walk close to the windows of the house. It came always at the same time, "just at the edge of dark," as they say here, and it always took the same route and disappeared at the same place.
