But in the opinion of an eminent agricultural chemist whom I have specially consulted on the subject, nitrogen, if applied in slowly decomposing form, as for instance, in the shape of oil-cake, would only be lost in an infinitesimal degree, but still he admits that there would be a loss, and as we cannot tell what that loss may amount to under the influence of our tropical climate and deluges of rain, it would be safe to assume that nitrogen, as well as lime, should be put down at short intervals and, in order to make up for the escape of these manures from the soil, in larger proportions than either phosphoric acid or potash.
The young man abandoned himself to the bitterness of his thoughts; he asked himself whether the bright object of his hopes would not flee from him day by day, as that phosphoric light fled from him in the horizon, step by step.
Kolloide!, 10 , 132-146. A good grade of material should be secured. It can be successfully used for the titration of hydrochloric, nitric, sulphuric, phosphoric, and sulphurous acids, and is particularly useful in the determination of bases, such as sodium, potassium, barium, calcium, and ammonium hydroxides, and even many of the weak organic bases.
"You see this two-eight-two fertilizer contains eight per cent. of so-called 'phosphoric acid' and two per cent. of potash, and those constituents may be worth much more than the nitrogen; but, so far as nitrogen is concerned, the two hundred pounds would cost from thirty to forty dollars in the best nitrogen fertilizers in the market, such as dried blood or sodium nitrate."
"Now," said Peterkin gravely, "that brute is a heartless monster; I'll have nothing more to do with it." "I'm pretty sure now," said Jack, "that it is merely a phosphoric light; but I must say I'm puzzled at its staying always in that exact spot."
I also was much puzzled, and inclined to think with Jack that it must be phosphoric light, of which luminous appearance we had seen much while on our voyage to these seas. "But," said I, "there is nothing to hinder us from diving down to it, now that we are sure it is not a shark." "True," returned Jack, stripping off his clothes. "I'll go down, Ralph, as I'm better at diving than you are.
"Vah!" he cried, with a senseless burst of laughter. However, the movement of the bass was accelerated, and, in proportion as it described a wider angle, Quasimodo's eye opened also more and more widely, phosphoric and flaming. At length the grand peal began; the whole tower trembled; woodwork, leads, cut stones, all groaned at once, from the piles of the foundation to the trefoils of its summit.
The earth on which he walked, the black earth, leaving phosphoric footmarks behind him, was composed of the mouldered bodies of millions of men who had passed away in the centuries during which the city existed. He shuddered as he moved; he hastened, yet could not go fast, his numbed limbs would not permit him.
If called upon to name the exact quantity and kind of manure for tomatoes, without any knowledge of the soil or its previous condition, I would say 8 to 10 tons of good stable manure worked into the soil as late as possible in the fall or during the winter and early spring and 300 to 600 pounds of commercial fertilizer, of such composition as to furnish 2 per cent. nitrogen, 6 per cent. phosphoric acid and 8 per cent. potash scattered and worked into the row about the time that the plants are set.
The noise of a heavy sea beating against the ship's side in a gale. It was over now, and he was keeping the midnight watch on deck, gazing upon the liquid green of the waves, which, heaving and seething after storm, were lit with phosphoric light, and as the ship held steadily on her course, poured past at the rate of twelve knots an hour in a silvery stream.
