I was told that the cattle grazing on a certain declivity at Tornoea die to the number of two or three hundred in the course of the summer. I must examine whether the cause of this may not be the Water Hemlock (_Cicuta aquatica_). Could not meadows be freed from their wart-like tumps by burning? These swellings might be cut off with an oblique hatchet, in spring after the frost ceases, and burnt in a heap; their ashes would serve as a valuable manure for the corn-field. Sandy grounds are rendered fertile with bog-earth; clay with sand. _Ledum_ (_palustre_) is laid among corn in the barns, to drive away mice. I here obtained some of Nasaphiel's silver ore, and the curious iron ore of Lulean Lapmark, called _gubbsilfver_ (old man's silver). The mine is not yet exhausted. The working of it had been for some time discontinued, but it is now resumed. It yields sixty per cent. It is situated a mile distant from Jockmock, and is called Rutawari. I procured also from the parish of Pithoea some pencil lead, or lead-like _mica_ (black lead) which blackens the fingers. The weather continued extremely fine, which in the opinion of the common people portended a good harvest. _June 25._ Sunday.--After divine service, I took leave of Lulea, in order to proceed to Lulean Lapmark, and arrived at the river of Lulea. I was informed that the salmon, which remain all winter in the Western Ocean, proceed gradually, as spring advances, up the river to this place to spawn. They enter the river about the middle of May, and reach this part of it by midsummer. Hooks have been found sticking in the side of some of the fish, which proved their having been here before. The _Subularia_, a new _Melampyrum_[53], and _Pedicularis_ (_sylvatica_) with a white flower, occurred to me at Sunnerby. The white bog-moss (_Sphagnum palustre_) powdered, is applied to excoriations in the skin of young children. Towards evening I found in a sand-hill a loose kind of sandstone containing three per cent of iron. [53] What this was does not appear. _M. pratense_ and _sylvaticum_ only have been found in Lapland. _June 26._ I gathered _Gramen paleaceum_ (_Juncus bufonius_), both kinds of _Tetrahit_ (_Galeopsis Tetrahit_ and _G. versicolor_, _Fl. Brit._), _Geranium_ (_sylvaticum_) with a pale white flower. At Bredacker I noticed the _Conyza_ (_Erigeron uniflorum_ or _E. acre_), the purple-flowered Millefoil (_Achillea Millefolium_), and the _Cirsium_ (_Carduus heterophyllus_.) The Laplanders boil all their meat very thoroughly, and treat their guests with grease, by way of dainty, which is eaten with a spoon. They milk their reindeer twice a day. Each gives not more at a time than half a pint, or at the utmost three quarters.
