It appears from the researches of Liebig and other eminent chemists, that when wood and vegetable matter are buried in the earth exposed to moisture, and partially or entirely excluded from the air, they decompose slowly and evolve carbonic acid gas, thus parting with a portion of their original oxygen.
Hence the necessity of regularly flushing the sewer with water, which removes from the sides the substances that have attached themselves thereto, and which, without such precaution, soon decompose. In a word, it is necessary that a perfect washing shall be assured, and this can be done only by heavy rains or by strong currents of water.
Each coop is high and wide enough to comfortably accommodate the chickens, and long enough to contain from five to twelve chickens. The chickens stand on slats, beneath which are dropping-boards that may be drawn out for cleaning. The dropping-boards and feeding-troughs are often made of metal. Strict cleanliness is enforced. No droppings or feed are allowed to accumulate and decompose.
I believe artists are already giving up the worst of vehicles, the meguilp, made of mastic, of all the varnishes the most ready to decompose, as well as to separate the paint, and produce those unseemly gashes which have been the ruin of so many pictures.
It is necessary to have a system of compression which does not require the constant introduction of grease or of foreign materials into the machine. 4. The liquid must be stable, it must not decompose by the frequent changes of condition, and it must not exert chemical action on the metals of which the apparatus is constructed. 5.
But if the same substances be submerged in water, they decompose more gradually; and if buried in earth, still more slowly; as in the familiar example of wooden piles or other buried timber.
They are fashioned like perfect vegetable structures, opening fan-shaped upon crystal stems, and catching the sunbeams with the brilliancy of diamonds. Taken at certain angles, they decompose light into iridescent colours, appearing now like emeralds, rubies, or topazes, and now like Labrador spar, blending all hues in a wondrous sheen.
A refractory clay sleeve, 41, protects the lower part of the cylinder, 15, from the fire, and diminishes the smoke passages at 42. The vapor produced makes its way vertically through a layer of charcoal placed between the evaporating vessel, 14, and the receiver, 17, and serving to decompose the aqueous vapor formed.
Glue waste is a very coarse, lumpy manure, and requires a great deal of severe manipulation, if it is to be applied the first season. A better way is to compost it with soil, layer with layer, having each layer about a foot in thickness, and so allow it to remain over until the next season, before using. This will decompose most of the straw, and break down the hard, tough lumps.
At one place a whole family had been crushed by a projectile. Dead Dervishes, already in the fierce heat beginning to decompose, dotted the ground. The houses were crammed with wounded. Hundreds of decaying carcasses of animals filled the air with a sickening smell.
