Страница 123 - And he gave it for his opinion, that whoever could make two ears of corn, or two blades of grass to grow upon a spot of ground where only one grew before, would deserve better of mankind, and do more essential service to his country, than the whole race of politicians put together.
Страница 147 - 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 148 - Unfading as motionless, the worm frets them not, and the autumn wastes not. Strong in lowliness, they neither blanch in heat nor pine in frost. To them, slow-fingered, constant-hearted, is entrusted the weaving of the dark, eternal tapestries of the hills ; to them, slowpencilled, iris-dyed, the tender framing of their endless imagery.
Страница 148 - 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 86 - 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 122 - 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 216 - Here is a book which should be in the hands of every boy in the kingdom in whose mind it is desirable to implant a true ideal of life, and a just notion of the proper objects of ambition ; and we may congratulate Mr. Page upon having carried out his task with all possible care and skill. ' Leaders of Men ' is every way an admirable volume.
Страница 114 - 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...
