Página 207 - The horses fed the corn ration were used the same number of hours in the military drill and in the maneuvers, and were ridden at the same g-ait as those fed exclusively on oats, and it was practically impossible to perceive the least difference between the two classes.

A careful record showed that the sickness and mortality were the same with horses on the two rations.
Página 342 - ... small amounts of the less costly mineral fertilizers, even in the worn-out soils of the Eastern States. With this help it has gathered its nitrogen from natural sources, and holds it readily to be fed out on the farm and returned in the form of manure for other crops. In other words, the experiments thus far imply that corn has, somehow or other, the power to gather a great deal of nitrogen from soil or air, or both; that in this respect it comes nearer to the legumes than the cereals; that,...
Página 275 - The bisulphide is usually applied in tight bins at the rate of a pound to a pound and a half to the ton of grain, and in more open bins a larger quantity is used. Mr. HE Weed, who has experimented -with this insecticide in Mississippi, however, claims that 1 pound to 100 bushels of grain is amply sufficient to destroy all insects, even in open cribs. Bins may bo made nearly air-tight by a covering of cloths or blankets.
Página 341 - ... would half starve for lack of it, and this in the face of the fact that leguminous plants contain a great deal of nitrogen and cereals relatively little. Hence a heavy nitrogenous manuring may be profitable for wheat and be in large part lost on clover. To get some more definite information as to the relation of our more common cultivated plants to the nitrogen supply, a "special nitrogen experiment...

Página 342 - The important fact, however, is this: The corn plant has in these trials shown itself capable of getting on and bringing fair yields with small amounts of the less costly mineral fertilizers, even in the worn-out soils of the Eastern States. With this help it has gathered its nitrogen from natural sources, and holds it readily to be fed out on the farm and returned in the form of manure for other crops. In other words, the experiments thus far imply that corn has, somehow or other, the power to gather...
Página 264 - With the mom careful and thorough methods of cultivation in the North this insect will have no chance for its life. It will reach its maximum in localities like parts of South Carolina where corn is simply stripped for fodder in early August and the bare stalk with the ear attached stands until after the cotton is picked, ginned, and shipped, and where even after the ears are harvested the stalks are seldom burned. In Virginia, however, the conditions are nearly as favorable for the continuous development...
Página 250 - Rotting grain is, indeed undoubtedly preferred by this insect, but it has occasionally been seen to infest kernels which had begun to grow. It lives normally in old sod, feeding chiefly, or perhaps altogether, on decaying vegetation there, and will be found in noticeable numbers in corn fields only where the field was in grass the preceding year. These maggots penetrate and hollow out the kernel, often leaving nothing more than an empty hull. A score or more of them may infest a single grain.
