(Here follow, in the manuscript, sketches of the leaves, with Latin descriptions, of _Salix phylicifolia β_, _pentandra_, _caprea_ and _myrtilloides_, to be found more complete in the _Flora Lapponica_.) Close to the shore, on the right of the ferry of Gaddewick, is a considerable spring, named Kall Källa, or Cold Spring, having a strong current and abounding with ochre, which is deposited abundantly along its course. The water bears a silvery film, and has a mineral taste, though not a strong one. It gushes forth with impetuosity, and never freezes in its course to the river, which is about eighteen ells distant. No high hill is near, but it springs from a swelling bank about two ells in perpendicular height above the level of the river. The mouth of the spring is towards the north-east. The inhabitants use it for washing. In places near the highway, where the people had laid bridges, the soil appeared very thin. The gravel and sand were commonly about a span deep in moist places; in dry ones much more. The clay was often two ells in thickness, under which gravel again occurred. Between the dark-coloured sand and the clay, as well as where the clay terminated, especially near the sand, runs water, which deposits clay, as the abovementioned spring does ochre. I noticed the following insects. [Illustration] 1. A large black Capricorn Beetle, variegated with a lighter hue. (_Cerambyx Sutor_, the female.) The horns were longer than the body, black, consisting of ten joints, each joint ash-coloured at its base. Body black, rugged, its wing-cases besprinkled here and there with clustered dirty spots. Abdomen cylindrical, covered towards the thorax with beautiful red lice, (_Acarus coleoptratorum_). 2. A minute black fly, with a roundish body and white wings, (_Culex equinus_). This infested the horses in infinite multitudes, running under their mane, and attacking them with great fierceness, being not easily driven off. (See its figure subjoined to the former.) 3. A grey Gnat, with striated wings, a blackish body, and black legs surrounded with white rings. (Mentioned, in the _Fauna Suecica_, as a large variety of _Culex pipiens_, the Common Gnat.) This cruelly tormented me and my most miserable horse. Its wings are whitish, appearing striated near the veins by the refraction of the sun's rays. The thorax was hairy, especially underneath. Abdomen oblong, dotted with black at the sides. All the other parts were grey. While the insect feeds, it raises up its hind feet into a horizontal posture. If I stooped ever so little whilst walking in the meadows, my nostrils and eyes were filled with these gnats. _June 22._
