Only one external source can be named: the falling of meteors into the sun must yield some heat just as a shooting star yields some heat to our atmosphere, but the question is whether the quantity of heat obtainable from the shooting stars is at all adequate for the purpose.
Although enormous single crops of mangels [[Table X]].--Decennial Average Yields in Great Britain of Wheat, Barley and Oats-Bushels per acre.
The general average yields of the corn crops are not fairly comparable one with the other, because they are given by measure and not by weight, whereas the weight per bushel varies considerably.
For purposes of comparison it would be much better if the yields of corn crops were estimated in cwt.
This, indeed, is the practice in Ireland, and in order to incorporate the Irish figures with those for Great Britain so as to obtain average values for the United Kingdom, the Irish yields are calculated into bushels at the rate of 60 lb to the bushel of wheat, of beans and of peas, 50 lb to the bushel of barley and 39 lb to the bushel of oats.
The yields in the experimental wheat-field at Rothamsted - where there is no change either of land or of treatment - indicate this.
The following figures show the average yields per acre of the selected plots at Rothamsted over six 8-yearly periods from 1852 to 1899, and afford evidence that the higher yield of later years is due to the seasons: Bushels (of 60 lb) Average of - per acre.
By far the greater proportion of those constituents remains in circulation in the manure of the farm, whilst the remainder yields highly valuable products for sale in the forms of meat and milk.
The process is repeated every alternate year, until the tree no longer yields the resin in abundance, which under favourable circumstances it will do for twenty years or more.
Its great value to the English forester is as a "nurse" for other trees, for which its dense leafage and tapering form render it admirably fitted, as it protects, without overshading, the young saplings, and yields saleable stakes and small poles when cut out.
Those who argue they should not say there is no way for poor countries to compete with mechanized Western farming and the extremely high yields it produces.
And, by the way, who estimates the value of the crop which nature yields in the still wilder fields unimproved by man?
Farmer Joe began using a new fertilizer in hopes that it would boost his crop yields.
It is hunted chiefly for the sake of the ivory of its immense tusks, of which it yields the principal source of supply to the European market, and the desire to obtain which is rapidly leading to the extermination of the species.
The acid, when distilled slowly, is decomposed and yields a and 0-angelica lactones.
Pasteur found that, when cane sugar was fermented by yeast, 49.4% of carbonic acid and 51.1% of alcohol were produced; with expressed yeast juice cane sugar yields 47% of carbonic acid and 47.7% of alcohol.
Mannheim is the chief commercial town on the upper Rhine, and yields in importance to Cologne alone among the lower Rhenish towns.
It is monobasic and yields salts which only crystallize with great difficulty; when liberated, from these salts by a mineral acid it forms a syrupy nonvolatile mass.
The sea produces three different seals, which often ascend rivers from the coast, and can live in lagoons of fresh water; many cetaceans, besides the " right whale " and sperm whale; and the dugong, found on the northern shores, which yields a valuable medicinal oil.

On oxidation with chromic or nitric acids, or potassium permanganate, it yields nicotinic acid or (3-pyridine carboxylic acid, C 5 H 4 N CO 2 H; alkaline potassium ferricyanide gives nicotyrine, C10H10N2, and hydrogen peroxide oxynicotine, C10H14N20.
By passing the vapour of this compound through a red-hot tube, it yields the isomeric a0- pyridylpyrrol, the potassium salt of which with methyl iodide gives a substance methylated both in the pyridine and pyrrol nuclei.

Cotton is grown in every county of the state, but the large yields are in the Delta (Bolivar, Coaohma, Washington, Yazoo and Leflore counties), the greatest cotton-producing region of the world, and in Monroe, Lowndes and Noxubee counties on the Alabama border.
The best wine grows in Kakhetia, a district lying north-east and east of Tiflis; this district alone yields nearly 8 million gallons annually.
But all these are insignificant in comparison with the mineral oil industry of Baku, which in normal times yields annually between ten and eleven million tons of crude oil (naphtha).
Sheep were small and their fleeces light, nevertheless, owing to the meagreness of the yields of cereals' and the demand for wool for export, sheep-farming was looked to, as early as the 12th century, as the chief source of profit.
Acreage and Yields of British Crops.
The effects of a prolonged [[Table Ix]].-Estimated Annual Average Yield per Acre of Crops in spring and summer drought, like that of 1893, are exemplified in the circumstance that four corn crops and the two hay crops all registered very low average yields that year, viz.
The mean values at the foot of the table-they are not, strictly speaking, exact averages-indicate the average yields per acre in the United Kingdom to be about 31 bushels of wheat, 33 bushels of barley, 40 bushels of oats, 28 bushels of beans, 26 bushels of peas, 44 tons of potatoes, 134 tons of turnips and swedes, 184 tons of mangels, 32 cwt.
