The grandest picture of these ancient events is offered by the Mosenberg, near Manderscheid, a mighty volcano which commands an extensive view of the country. Two old craters lie on its double top, one of which has fallen in, forming a short rocky valley, but the other retains its original regular shape. In the circular funnel, whose walls consist of masses of lava stone, rests a quiet, black lake, that looks very mysterious to the wanderer. Only low juniper bushes grow near the crater, bearing witness to the barrenness of the land. From the foot of this mountain an immense stream of lava, as wide and deep as a glacier, broke forth and flowed into the valley, where the end of the stream is still to be seen in a high, steep wall of rock.
THE "CHEESE GROTTO" AT BERTRICH BATHS.
Similar sights are met all through this western volcanic region, and we can consider the mineral and acid springs, which are very numerous, as the last traces of the former disturbances, the products of the decomposition of the volcanic stones buried in the earth. At Bertrich Baths there are hot springs which were known to the Romans, for numerous antiquities dating from their time have been excavated here. Near these springs, at Bertrich, there is a "Cheese Grotto," which is a break through the foot of a stream of lava, the stones of which have not assumed the usual form of solidified columns, but have taken flat, round shapes which resemble the forms of cheeses.
Now we have completed our wanderings, which required only a few days, although they extended over this whole volcanic region, and which end here on the Moselle.—Ueber Land und Meer; Allgemeine Illustrirte Zeitung.

THE "METEOROLOGISKE INSTITUT" AT UPSALA, AND CLOUD MEASUREMENTS.
The Meteorological Institute at Upsala has gained so much fame by the investigations on clouds which have been carried on there during the last few years, that a few notes on a recent visit to that establishment will interest many readers.
The Institute is not a government establishment; it is entirely maintained by the University of Upsala. The personnel consists of Prof. Hildebrandsson, as director; M. Ekholm and one other male assistant, besides a lady who does the telegraphic and some of the computing work.
