[14] Its perpendicular height is two hundred Swedish ells. See _Dissert. de Angermanniâ_.
[15] This cavern has been visited by other naturalists since the time of Linnæus, among whom was Dr. Olaf Swartz, the present Bergian Professor of Botany at Stockholm, well known by his various excellent publications, who gathered here the same _Byssus_ (_cryptarum_) which Linnæus found in the other cavern at Brunæsberget. Both their original specimens are now in my possession.
Having taken leave of this mountain, I had scarcely continued my journey a quarter of a mile before I found a great part of the country covered with snow, in patches some inches deep. The pretty spring flowers had gradually disappeared. The buds of the birch, which so greatly contribute to the beauty of the forests, were not yet put forth. I saw nothing but wintry plants, the heath and the whortle-berry, peeping through the snow. The high mountains which surround this tract, and screen it from the genial southern and western breezes, added to the thick forests which will hardly allow the first mild showers of spring to reach the ground, may account for the long duration of the snow.
This part of the country is very mountainous, and is watered by many small rills, originating on the sides of the mountains from the copious rains falling upon them, and running from thence, by various channels, to swell the streams of Helsingland and Medelpad.
The cornfields afford a crop two years successively, and lie fallow the third. Rye is seldom or never sown here, being too slow in coming to perfection, so that the land, which must next receive the Barley, would be too much exhausted. The ploughs are made with two transverse beams on one side, that the sods may be turned the first time the land is ploughed, as will presently be more particularly explained.
After going to church at Natra, I remarked some cornfields, which the curate of that place had caused to be cultivated in a manner that appeared extraordinary to me. After the field has lain fallow three or four years, it is sown with one part rye and two parts barley, mixed together. The seed is committed to the ground in spring, as soon as the earth is capable of tillage. The barley grows rank, ripens its ears, and is reaped. The rye in the mean while goes into leaf, but shoots up no stem, as the barley smothers it and retards its growth. After the latter is reaped, the rye advances in growth, and ripens the year following, without any further cultivation, the crop being very abundant. The corn so produced is called Kappsäd.
