and if forcibly detached, die. I therefore bring the hammer and chisel into requisition, and split off a considerable fragment of the solid stone, which then, with the plant adhering to it, is placed in the Aquarium. This is often a difficult, always a delicate operation; the rock is frequently so hard as to resist the action of the chisel, or breaks at the wrong place; sometimes, on the other hand, it is so soft and friable as to crumble away under the implement, leaving only the isolated plant deprived of its attachment; and sometimes at the first blow, the sea-weed flies off with the vibration of the shock. Often we have to work under water, where the force of the blows is weakened and almost rendered powerless by the density of the medium, and where it is next to impossible to see with sufficient clearness to direct the assault.
As the plants are detached they are placed one by one in security. The finer and more delicate ones, as the Delesseria for instance, are immediately dropped into a jar of water; for only a few minutes' exposure of their lovely crimson fronds to the air, would turn them to that dull orange colour, already mentioned as the sign of incipient decay. The hardier sorts are laid in the basket,—a layer of damp refuse-weed being first put in to receive them,—and covered lightly with damp weed. The degree of moisture thus secured is sufficient to preserve many species from injury, for hours. Thus they are brought home.
