86 ページ - 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.
122 ページ - 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.
216 ページ - 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.
