Page 230 - And whosoever shall fall on this stone shall be broken: but on whomsoever it shall fall, it will grind him to powder.
Page 217 - The thing that hath been, it is that which shall be; and that which is done is that which shall be done : and there is no new thing under the sun. Is there anything whereof it may be said, See, this is new? it hath been already of old time, which was before us.
Page 284 - It is a marvellous reflection that the whole of the superficial mould over any such expanse has passed, and will again pass, every few years through the bodies of worms. The plough is one of the most ancient and most valuable of man's inventions ; but long before he existed the land was in fact regularly ploughed, and still continues to be thus ploughed by earth-worms.
Page 101 - ... fully recovered. He had no further trouble from the disease. I have not learned that the disease appeared among any other cattle in this town, but I have the impression that in the town of Haverhill, a few miles north of this place, several young creatures died with it. I cannot speak so positively in regard to that, but I think that Dr. OD Eastman, who was then living here (now lives at Woodsville), had knowledge of the facts, and thought it was the same disease that appeared here. If you should...
Page 404 - Once well incorporated with the soil, it gradually becomes reverted phosphoric acid. Reverted (reduced or precipitated) Phosphoric acid means strictly, phosphoric acid that was once easily soluble in water, but from chemical change has become insoluble in that liquid. In present usage the term signifies the phosphoric acid (of various phosphates) that is freely taken up by a strong solution of ammonium citrate, which is therefore used in analysis to determine its quantity.
Page 407 - But the rule has many exceptions, and in particular instances the trade- value cannot always be expected to fix or even to indicate the agricultural value. Fertilizing effect depends largely upon soil, crop and weather, and as these vary from place to place, and from year to year, it cannot be foretold or estimated except by the results of past experience, and then only in a general and probable manner.
Page 404 - When very finely pulverized (" floats ") they more often act well, especially in connection with abundance of decaying vegetable matters. The phosphate of calcium in raw bones is nearly insoluble, because of the animal matter of the bones, which envelops it ; but when the latter decays in the soil, the phosphate remains in essentially the " reverted

Page 406 - But the valuation is not to be too literally construed, for analysis cannot decide accurately what is the form of nitrogen, etc., while the mechanical condition of a fertilizer is an item whose influence cannot always be rightly expressed or appreciated.
Page 406 - Valuation" are two-fold: 1. To show whether a given lot or brand of fertilizer is worth, as a commodity of trade, what it costs. If the selling price is not higher than the valuation, the purchaser may be tolerably sure that the price is reasonable. If the selling price is twenty to twenty-five per cent, higher than the valuation, it may still be a fair price; but in proportion as the cost per ton exceeds the valuation there is reason to doubt the economy of its purchase.
