Gorge near Rosseck. (Valvasor, _Die Ehre des Herzogthumes Crain_, vol. I., page 243 and page 517 ; Petruzzi in Haidinger's _Berichte_, etc., vol. VII., page 64.)--Behind the ruined castle of Rosseck, on the Pograca Mountain in the Krain, is a gorge, at whose bottom are four little holes containing ice most of the year. Valvasor wrote of this cave in 1689: "Near Rosseck immediately back of the castle there opens a mighty cavern entirely in stony rock, and yawns in the shape of a cauldron down into the earth. Above as wide as a good rifle shot, but below quite narrow. And there underneath there are many holes where the ice remains through the whole summer. From such ice have Duke Frederick Graf and Duke von Gallenberg daily made use in summer to cool their wine. Six years ago I descended there in the month of August, and found ice enough in all the holes." In the same volume Freiherr Valvasor elaborates his remarks about this cave and that at Latzenberg, repeating in the main the observations in the paragraph just given. He says: "There hang also long icicles which are quite pleasant to look at. * * * This ice breaks all too easily and quickly. * * * Contrarywise, however, this ice lasts much longer in the sun and the heat than other ice. * * * Some might think it would eventually turn into stone: this, however, does not happen: for it remains only in summer and disappears in winter: as I can say for certain, as I have been in myself in the winter as well as in the summer time. * * * For as in the summer the floor is quite covered with ice: it makes walking so dangerous and bad that one cannot take a step without climbing irons; but in the winter time one goes safely and well. * * *" Freiherr Valvasor was evidently an accurate observer, and, if for his word "winter" we substitute "autumn," his account will be much more nearly correct than might have been expected two centuries ago.
