Strana 379 - Ever charming, ever new, When will the landscape tire the view ! The fountain's fall, the river's flow, The woody valleys, warm and low ; The windy summit, wild and high, "Roughly rushing on the sky ! The pleasant seat, the ruin'd tower, The naked rock, the shady bower ; The town and village, dome and farm, Each give each a double charm, As pearls upon an Ethiop's arm.
Strana 220 - The first colonists of Virginia found a country, the soil of which was similar to that mentioned above; harvests of wheat and tobacco were obtained for a century from one and the same field without the aid of manure, but now whole districts are converted into unfruitful pasture land, which without manure produces neither wheat nor tobacco. From every acre of this land, there were removed in the space of one hundred years 1,200 Ibs. of alkalies in leaves, grain, and straw...
Strana 169 - Nile], and then the water gushing out is conducted from one rill to another by the gardener, who is always ready, as occasion requires, to stop and divert the torrent, by turning the earth against it with his foot, and opening, at the same time, with his mattock. a new trench to receive it.
Strana 378 - Now, I gain the mountain's brow, What a landscape lies below ! No clouds, no vapours intervene ; But the gay, the open scene Does the face of Nature show, In all the hues of Heaven's bow ! And, swelling to embrace the light, Spreads around beneath the sight.
Strana 505 - March, when the snow had a depth of 10 inches. Ammonia was set free from these crystals by the addition of hydrate of lime. The inferior layers of snow, which rested upon the ground, contained a quantity decidedly greater than those which formed the surface. It is worthy of observation, that the ammonia contained in rain and snow water, possessed an offensive smell of perspiration and animal excrements, — a fact which leaves no doubt respecting its origin.
Strana 216 - The most easy and practical mode of effecting their division is to pour over the bones, in a state of fine powder, half of their weight of sulphuric acid diluted with three or four parts of water...
Strana 216 - In a few seconds the free acids unite with the bases contained in the earth, and a neutral salt is formed in a very fine state of division.
Strana 216 - Ibs. of bone dust is sufficient to supply three crops of wheat, clover, potatoes, turnips, &c., with phosphates. But the form in which they are returned to the soil does not appear to be a matter of indifference. For the more finely the bones are reduced to powder, and the more intimately they are mixed with the soil, the more easily are they assimilated.
Strana 520 - If about twenty small cart loads of dung can be brought on each acre of the newly trenched ground, the progress is much more rapid. Potatoes are then the first crop, and generally give a good return. The same quantity of dung is required for the next crop, which is rye, in which clover is sown in the succeeding spring ; and a small portion...
Strana 320 - Lecture, a small quantity of a matter analogous to albumen ; but it seems that the azote which forms a constituent part of this matter, is derived from the atmosphere. The dry bean leaf, when...
