The strength of the Beaver in its fore teeth, so as to cut through the trunk of the largest aspen trees, is I believe beyond that of any other animal. _May 29._ Very early in the morning I quitted Genom in a haœp or small boat, such as shall be hereafter described, proceeding along the western branch of the river of Umoea; for the river which takes its name from that place divides into two branches near Gresele, two miles from Umoea. One branch comes from Lycksele, the other, as I was told, from Sorsele. By the western branch, as I have just mentioned, we proceeded to Lycksele. When the sun rose, nothing could be more pleasant than the view of this clear unruffled stream, neither contaminated by floods, nor disturbed by the breath of Æolus. All along its translucent margin the forests which clothed its banks were reflected like another landscape in the water. On both sides were several large level heaths, guarded by steep ramparts towards the river, and these were embellished with plants and bushes, the whole reversed in the water appearing to great advantage. The huge pines, which had hitherto braved Neptune's power, smiled with a fictitious shadow in the stream. Neptune however, in alliance with his brother Æolus, had already triumphed over many of their companions, the former by attacking their roots, while the latter had demolished their branches. We passed several small islets separated from the main land by the action of the current, as _Calnäsholm_ (the isle of Calnäs), &c. Close to the shore were many _Charadrii Hiaticulæ_ (Ringed Plovers) and _Tringæ_ (Sandpipers). One of the latter my companions shot, but destroyed it so completely that we obtained only a wing and a leg entire, the remaining parts being so torn that I could not make out the species. The foot consisted of four toes, of which the hinder one was very small, and the two external ones joined by a web at their base. A little further on a couple of young owls were suspended on a tree. On my inquiring what these birds had done to be so served, the rower made me remark, on the most lofty of the fir trees, concave cylinders of wood, closed at top and bottom, and having an aperture on one side. These cylinders are placed on the highest part of the trees, in order to tempt Wild ducks to lay their eggs in them, and they are afterwards plundered by the country people. In one of these nests a brood of young owls had been hatched instead of young ducks. Presently afterwards the breast of a Cock of the wood was given me to eat, by way of a bait. It had been shot this spring and dried in the sun, without being previously cooked; neither had it so many longitudinal cuts as that I have described in the foregoing pages.
