After trimming off all but a few of the upper leaves, which should be clipped to reduce transpiration, the cuttings never more than 4 or 5 inches long should be plunged nearly full depth in well-shaded, rather light, porous, well-drained loam where they should remain undisturbed until they show evidences of growth. Then they may be transplanted.
"The amount of water taken from the soil by the trees of a forest and passed into the air by transpiration is not so large as that accumulated in the soil by the diminished evaporation under the branches. Hence, there is an accumulation of water in the shade of forests which is released slowly by drainage.
Does not public morality demand that it should be so considered? There has been a mutual exchange of hearts, of transpiration." On the right of children to be supported and fed although of age, he says: "Will you allow a father to drive a girl of fifteen out of his house?
Through the stomata, when open, free interchange may take place between the external air and that within the leaf, and thus transpiration be much facilitated. When closed, this interchange will be interrupted or impeded." In these lessons, however, it is not desirable to enter upon subjects involving the use of the compound microscope. Dr.
If one of these wattles is burnt to the ground, but yet retains sufficient life to enable it to shoot from the charred stem, the new growth will be of pinnate leaves, shortly to be abandoned for the substitutes, which are of a form which checks transpiration and fits the plant to survive in specially dry localities.
A flowing thing, shapeless and nameless, is all that the animal is, if we add abundant ramified air ducts, some nervous filaments and, under the skin, a thin layer of muscular fibers. A condition of this kind accounts for a fatty transpiration through the skin when the Anthrax' sucker is at work.
Neither is transpiration, as in plants, a thing to be valued, nor respiration, as in domesticated animals and wild beasts, nor the receiving of impressions by the appearances of things, nor being moved by desires as puppets by strings, nor assembling in herds, nor being nourished by food; for this is just like the act of separating and parting with the useless part of our food.
To prevent undue evaporation, the surface also is covered with a thick, shiny skin a sort of vegetable macintosh, which effectually checks all unnecessary transpiration. Of this desert type, then, the cactus is the furthest possible term.
To differentiate between cacti and other plants that look like cacti is very easy. All cacti have fine hair at the base of each thorn. The so-called thorns are in fact highly modified leaves which prevent loss of water through transpiration. If one ever gets pricked by cacti thorns, one should take cellotape, place it over the area where the thorns have penetrated the skin and then peel it off.
Indeed, in the summer time, I have found wonderful benefit in bathing my head with a decoction of some hot and aromatical herbs, in a lixivium made of the ashes of vine branches; and when my head is well washed with this, I immediately cause abundance of cold fountain water to be poured upon me stillatim, for a good half-hour together; which for the present is not only one of the most voluptuous and grateful refreshments imaginable, but an incredible benefit to me the whole year after: for I never need other powdering to my hair, to preserve it bright and clean, as the gallants do; but which does certainly greatly prejudice transpiration by filling up, or lying heavy upon the pores.
