Page 158 - Heat the solution of soap, and add it boiling hot to the kerosene. Churn the mixture by means of a force pump and spray nozzle for five or ten minutes. The emulsion, if perfect, forms a cream, which thickens on cooling, and should adhere without oiliness to the surface of glass. Dilute before using one part of the emulsion with nine parts of hot water. The above formula gives three gallons of emulsion, and makes, when diluted, thirty gallons of wash.
Page 153 - ... repeated two and perhaps three summers is sufficient to either kill the tree outright, or so weaken it that bark-boring beetles can complete the work of destruction. We are now inclined to the opinion, then, that the Bud Tortrix is the sole or at least main cause of the destruction of spruces and firs in Cumberland...
Page 172 - When this is once observable, no leaf-eater thrives npon the foliage. Slight overpoisoning seems to have a tonic or invigorating effect on the tree. Preventive Effects of the Poison. — In this grove the elms that were poisoned in 1882 were attacked in the spring of 1883 less severely than were those which were not poisoned the previous year. This would seem to imply that the insects deposit mostly on the trees nearest to where they develop, and are only partially migratory before ovipositing.
Page 155 - This broad band extends out towards or connects with a preapical brown patch on the costa; it also sends an angle inwards behind the median vein, and again another angle outward opposite the inwardly-directed angle. There are often two distinct, costal, whitish dots (sometimes wanting) just before the apex, while the apex itself is brown. There is also a large brown patch in the middle of the wings near the outer edge. There are numerous fine, short, transverse, brown lines dividing the wing into...
Page 467 - In 1876 another writer says of this same region : " Within thirty years this was one of the most fertile spots of central Asia, a country which, when well wooded and watered, was a terrestrial paradise. But within the last twentyfive years a mania of clearing has seized upon the...

Page 137 - Hot water. — Every worm visible upon the cabbages may bo killed by the use of water at the temperature of 130° Fahrenheit or 55° Centigrade. The water may be boiling hot when put in the watering can, but it will not be too hot when it reaches the cabbage leaves. The thick fleshy nature of the. leaves enables them to withstand considerable heat with very little injury.
Page 185 - Two important facts shonld always be borne in mind in using these bagging-machines : 1st, that they should always be drawn, as far as possible, against the wind, if this be stirring ; 2d, that in proportion as the insects and the grain are advanced in growth, and the former become predisposed to roost, in that proportion the machines will prove more serviceable at night.
Page 471 - Azores, are inhabited by oxen without a hunch, which derive their origin from the aurochs. Every part of South America is inhabited by oxen without hunches, which the Spaniards and others have successively transported. Thus the wild and the tame ox, the European, the Asian, the American, and the African ox, the bonasus, the aurochs, the bison, and the zebu are, say historians, all animals of one and the same species, which, according to climate, food, and the different usages to which they have been...
Page 175 - The hose and bamboo combination was conceived of, and used as the lightest, long, stiff tube practicable for these purposes, and it has answered admirably. A similar pole, with a metallic tube in its interior, with a nozzle not producing the very fine mist desired, and lacking the side discharge, &c., was afterward learned of as being used in California.
