Стр. 46 - which the Indians call Usquahuitl; it is held in great estimation, and grows in the hot country. It is not a very high tree; the leaves are round and of an ashy colour. This tree yields a white milky substance, thick and gummy, and in great abundance.
Стр. 325 - In the next place it is shown that the yield was very materially increased by the use of manures, either in the form of artificial or natural supplies, and the differences in yield derived from these two forms are very slight, indicating that very much smaller amounts of actual plant food in quick acting forms were quite as useful as larger amounts of the less available forms in which the food exists in natural manure products. For the ten years, the fertilized plot received...
Стр. 325 - In the third place it is interesting to observe — and it is a point of great importance — the effect of an abundance of food in overcoming unfavorable weather or seasonal conditions. The year 1889 was extremely unfavorable, and the crop throughout the State was small. In this experiment the unmanured plot yielded at the rate of...
Стр. 325 - The manure strengthened and stimulated the trees, and enabled them successfully to resist such conditions as were fatal to the crop on the unmanured land. This point is one that is seldom considered in calculating the advantages to be derived from proper manuring, though it is of extreme value, since the expenses of cultivation, trimming, and interest on investment are quite as great in one case as in the other.
Стр. 127 - In one instance we have over 415 males from a single female, and while the number of males would average somewhat less than the females, taking the summer through, yet, having underestimated the females, the males may be estimated at the same number, giving a total of 3,216,080,400 descendants from a single insect in a single season. It is not to be expected, of course, that all the individuals from a scale survive and perform their function in life, but under favorable conditions, or in the case...
Стр. 325 - The first point of importance and value observed is in reference to the number of crops that were secured. On the unmauured land, the crops secured after eight years were so small as to materially reduce the average for the whole period, while for the manured land the average for the whole period was not only not reduced, but very materially increased; that is, the crops secured on these after the trees on the unmanured land had practically ceased to bear were greater proportionately than those secured...
Стр. 325 - This point is one that is seldom considered in calculating the advantages to be derived from proper manuring, though it is of extreme value, since the expenses of cultivation, trimming and interest on investment are quite as great in one case as in the other. Another experiment bearing upon this point, recently reported by the Cornell experiment station,* is also very instructive as indicating the need of manures for fruit trees, not only in reference to the amount removed, but also in reference...
Стр. 325 - ... pounds of potash. These amounts of plant food are compared with the amounts that would be removed by 20 years...
Стр. 204 - ... localities where the winters come early and are of unusual severity will be found greater difficulties in the production of sugar from the sugar beet than in those localities where the winters are light and mild, although the mean summer temperature of both localities may be represented by 70 o F.
Стр. 227 - ... of quite fresh lean beef in one piece in distilled water, and boiled for five minutes. Below the boiling point the meat fell into several pieces, and at the close of the experiment it had separated into coarse shreds. In the control experiments made without the juice the boiled meat was visibly harder. Hard boiled albumen, digested with a little juice at a temperature of 20° C., could after twenty-four hours be easily broken up with a glass rod.
