Страница 151 - Meek creatures! the first mercy of the earth, veiling with hushed softness its dintless rocks; creatures full of pity, covering with strange and tender honor the scarred disgrace of ruin, — laying quiet finger on the trembling stones, to teach them rest.
Страница 106 - If I wish for a horse-hair for my compass-sight I must go to the stable; but the hair-bird, with her sharp eyes, goes to the road. Immortal water, alive even to the superficies. Fire is the most tolerable third party. Nature made ferns for pure leaves, to show what she could do in that line.
Страница 88 - When the bee, thus provided, flies to another flower, or to the same flower a second time, and is pushed by its comrades into the bucket and then crawls out by the passage, the pollen-mass necessarily comes first into contact with the viscid stigma, and adheres to it, and the flower is fertilised.
Страница 151 - And, as the earth's first mercy, so they are its last gift to us. When all other service is vain, from plant and tree, the soft mosses and gray lichen take up their watch by the headstone.
Страница 124 - If a man walk in the woods for love of them half of each day, he is in danger of being regarded as a loafer; but if he spends his whole day as a speculator, shearing off those woods and making the earth bald before her time, he is esteemed an industrious and enterprising citizen.
Страница 116 - She is the fairies' midwife, and she comes In shape no bigger than an agate-stone On the forefinger of an alderman, Drawn with a team of little atomies Athwart men's noses as they lie asleep : Her waggon-spokes made of long spinners...
Страница 54 - Moth-traps and spring-guns set on these grounds," might be the motto of the Orchids. There are baits to tempt the nectar-loving Lepidopteru, with rich odours exhaled at night, and lustrous colours to shine by day ; there are channels of approach along which they are surely guided, so as to compel them to pass by certain spots; there are adhesive plasters nicely adjusted to fit their probosces, or to catch their brows ; there are hair-triggers carefully set in their necessary path, communicating with...
Страница 8 - The picture he gives us here of the Enticknapp household, with its Moravian and Quaker traditions, is one nearly perfect of its kind for sobriety of taste and freedom from all sentimental exaggerations.
Страница 128 - But how important an element enclosure is, I plainly saw near Farnham in Surrey. Here there are extensive heaths, with a few clumps of old Scotch firs on the distant hill-tops ; within the last ten years large spaces have been enclosed, and self-sown firs are now springing up in multitudes, so close together that all cannot live. When I ascertained that these young trees had not been sown or planted, I was so much surprised at their numbers that I went to several points of view, whence I could examine...
Страница 149 - Ascomycetes, a parasite which is accustomed to live upon, others' work ; its slaves are green algae, which it has sought out, or indeed caught hold of, and compelled into its service. It surrounds them, as a spider its prey, with a fibrous net of narrow meshes, which is gradually converted into an impenetrable covering ; but...
