I noticed also the Pondweed with leaves clasping the stem (_Potamogeton perfoliatum_, rare in Lapland); and a very large branched floating Water-grass, with cylindrical spikes, which I hesitate whether to separate from the _Gramen aquaticum geniculatum spicatum_, (of Bauhin and Rudbeck. _Alopecurus geniculatus_ of Linnæus. The grass of which he here speaks is _n._ 38 of his _Flora Lapponica._ _A. geniculatus_ β, _Sp. Pl._ 89.) The annexed figure represents the Norwegian cross-bow, used for shooting squirrels, which it will hit at the distance of twenty or thirty paces as certainly as a gun. It was curious to observe the dexterity with which one of the Laplanders hit a small fly, which I had set up for a mark, at the distance of thirty paces. [Illustration] The bow itself, a, a, a, made of steel, is two feet and a half long, two inches wide in the middle, gradually sloping off to the extremities, which are only one inch in width. Each end is rounded, with a notch, where the cord is fixed, which, when the bow is drawn, seems in danger of immediately slipping off, but it never does. The whole bow when at rest makes a curve of two inches; when strongly bent it forms one of seven. The cord b, fixed on at the ends b, b, is made of twisted hemp, as thick as one's finger, bound round with hempen thread, especially in the middle, where it is to receive the bolt. The stock c, c, made of wood ornamented with inlaid work of bone, is two feet and a half long, and half a palm broad, being half an inch thick towards the top, and an inch at the base. Its upper side is entirely covered with the above-mentioned inlaying, and quite even or flat, except towards the base or handle, where it is slightly concave. The part marked d on the bow, and D on a larger scale annexed, is the catch, like a pulley, which turns on an iron pin, and in the side of which is a projection, with a rectangular notch, see _fig._ 1 and 2. When the bow is bent, the angle at _fig._ 2 catches the cord, and is let go by means of the apparatus represented at c, c, by the side. As no human being is sufficiently strong to draw this bow with the hands alone, a strap of leather is fixed round the loins, ending in two iron hooks, which lay hold of the cord. One foot is put into the strap at the top of the bow, h, and then, by the exertion of the body, the bow is drawn till the cord catches the angle of the pulley D. [Illustration]
