1of their parts in contact, in order that individual rigidity may afford the combined strength necessary to withstand the strains of flexure and torsion to which the various parts of the plant are subjected.
3The rope-maker takes a quantity of hemp, reduced, by suitable means, to long fibres composed of bundles of elongated cells attached to each other by some agglutinant. He twists numbers of these into the form of a cord. He again twists a number of these cords into a strand. From several of the strands, in a similar manner, he finally constructs the rope; which is, in fact, composed of a complicated system of fibrous spiral springs. If this new, dry rope be strained between two fixed points, the amount of its tension may be ascertained by weights or other equivalent arrangement. If the rope be now saturated with water, the tension which it exerts at the two fixed points will be largely increased. This phenomenon is again due to the stiffening or increased rigidity of the fibrous spiral springs caused by the water absorbed by the cells; in short, to turgescence, each individual cell being suitably attached or agglutinated to its fellows by a substance naturally or artificially introduced for this purpose.
5Wood consists of numbers of elongated cells similarly attached to each other. If dry wood be saturated with water it will be found to change its form; it will be considerably enlarged laterally but not appreciably longitudinally—in common language, it swells. As it dries it resumes its original dimensions. This phenomenon is once more to be attributed to turgidity—to the increase and decrease of the strength or rigidity of the tiny cells, firmly attached to each other
