This is derived from the sap of the rock or sugar maple (Ater saccharinum), a large tree growing in Canada and the United States.
Hear me, then: I take that mast-head flame we saw for a sign of good luck; for those masts are rooted in a hold that is going to be chock a' block with sperm-oil, d'ye see; and so, all that sperm will work up into the masts, like sap in a tree.
The sap in these active tissues is alkaline, which has been interpreted as being in accordance with not appear to be concerned with digestion so directly as the others is pectase, which forms vegetable jelly from pectic substances occurring in the cell-wall.
During the development of the inflorescence there is a rush of sap to the base of the young flowerstalk.
The Hevea product is obtained annually by tapping the trees and coagulating the sap over a smoky fire, but the caucho is procured by felling the tree and collecting the sap in a hollow in the ground where it is coagulated by stirring in a mixture of soap and the juice of a plant called vetilla.
In his Statical Essays (1727) he gave an account of numerous experiments and observations which he had made on the nutrition of plants and the movement of sap in them.
The sap which flows in the spring is drawn off and boiled down to an agreeable spirit, or fermented with a birch-wine of considerable alcoholic strength.
In well-developed shoots the buds are generally double, or rather triple, a wood bud growing between two fruit buds; the shoot must be cut back to one of these, or else to a wood bud alone, so that a young shoot may be produced to draw up the sap beyond the fruit, this being generally desirable to secure its proper swelling.
This may possibly be the cell sap in their interior, which must exercise a slightly different hydrostatic pressure on the basal and, the lateral walls of the cells.
The best month for larch planting, whether for poles or timber, is November; larches are sometimes planted in the spring, but the practice cannot be commended, as the sap flows early, and, if a dry period follows, the growth is sure to be checked.
