In the smaller group, the Monocotyledons, the bundles are more numerous in the young stem and scattered through the ground tissue. Moreover they contain no cambium and the stem once formed increases in diameter only in exceptional cases. Vegetative organs.
The right of the campsor to some remuneration for risk was only gradually admitted, and forms the subject of much discussion amongst the jurists. This hesitation in allowing remuneration for risk was not peculiar to cambium, but, as we have seen above, was common to all commerce.
By the time the tree was eighty years old, only the small area of cambium indicated by the thin line marked 80 was still alive; and soon afterward the stem was completely "ringed," and dead, all the tissues being suffused with resin. Putting everything together, it is not difficult to explain the symptoms of the disease.
I saw one of these curious trees in full bloom a few days since between Edmonton and Enfield. The sap is changed into a viscid fluid, which circulates under the bark: this is called cambium. When it is too abundant it is effused, part of its water evaporates, and it becomes gum.
I now observed what at first appeared to be the hind leg of the farther side of the body protruding beneath, but in another moment noted my error, and saw that its sharp point had penetrated the bark, into which it soon sank quite deeply, and I realized that the ovipositor was now conducting its tiny eggs into the cambium layer of the bark.
The cells of each seem to know what particular elements they want from the soil, as of course they do. The vital activity of the tree goes on at three points in the leaves, in the rootlets, and in the cambium layer.
We know that the roots of trees insert themselves into seams in the rocks, and force the parts asunder. This force is measurable and is often very great. Its seat seems to be in the soft, milky substance called the cambium layer under the bark. These minute cells when their force is combined may become regular rock-splitters.
Those spines he must fold very close, even to the withdrawing of them into his orange colored cambium layers, for there is never an ouch from the group. These are summer's flowers for remembrance, the goldenrod and asters. She gives them to us and goes, making all early autumn glow with her memory thereby. But old man Barberry may have these if he will.
This is practically saying that cambium may be carried on under the same conditions as any other species of commerce. Biel says that cambium is only legitimate if the campsor has the motive of keeping up a family or benefiting the State, and that the contract may become usurious if the gain is not fair and moderate.
Endemann points out how the theologians and jurists unanimously insisted that cambium could not be justified except when the just price was observed, and that, when the doctrine attained its full development, the element of labour was but one of the constituents in the estimation of that price. Lib. The former two species of cambium were justifiable, whereas the last was condemned.
