The Petite Glacière du Pré de Saint-Livres. (Browne, _Ice Caves_, page 46.)--This is near the last cave at a slightly higher altitude. There is first a small pit, then a little cave, in which there is an ice slope. This passes under a low arch in the rock wall, and leads down into another small cave. Mr. Browne descended this ice stream, which was itself practically a fissure column and spread into the fan shape at the base. The lower cave was 22 meters long and 11 meters wide, and contained an ice floor and several fissure columns. The Glacière de Naye, above Montreux, Switzerland. (E. A. Martel, _Les Abimes_, page 397; _Spélunca_, 1895, vol. I., pages 107, 108; _Mémoires de la Société de Spéléologie_, vol. III., pages 246-254.)--This is called a _glacier souterrain_. It was discovered in 1893 by Professor Dutoit. There are fifty-four caves known among the Rochers de Naye, and only this one contains ice. It is a long narrow cave with two entrances and widest towards the base, which opens over a precipice. The altitude is high, the upper entrance being at an altitude of 1820 meters, and the lower of 1750 meters. The place is both a passage cave and a windhole. The snow falls into the upper entrance, and slides down, becoming ice in the lower portion. There are other connecting passages and hollows where the cold air cannot get in, and there ice does not form. Mons. Martel thinks that the ice formed during the winter is preserved by the draughts--due to the difference in level of the two openings--causing an evaporation and chill sufficient for the purpose. The Creux Bourquin. (E. A. Martel, _Les Abimes_, page 397.)--At Mauberget, near Grandson. This is a rock gorge 25 meters deep. At the bottom, on the 9th of July, 1893, was a mass of ice 38 meters long and 8 meters wide. The Glacière de Monthézy. (Browne, _Ice Caves_, page 97.)--This lies to the west of Neufchâtel, between the Val de Travers and the Val de Brévine, on the path between the villages of Couvet and Le Brévine, at an altitude of 1100 meters. The cave is nearly oval in shape, with a length of 34 meters and a width of 29 meters. The roof is from 1 meter to 3 meters high. There are three pits, about 20 meters deep, on different sides of the cave. The descent is made through the largest pit. On the 6th of July, 1864, Mr. Browne found the floor of the cave covered with ice, and icicles and columns in some places; he also saw a clump of cowslips (_primula elatior_) overhanging the snow at the bottom of the pit through which he descended. Pertius Freiss. (T. G. Bonney, _Nature_, vol. XI., page 327.)--It lies on the way to the Pic d'Arzinol, near Evolène, in the Val d'Hérens. A slip or subsidence of part of a cliff has opened two joints in the rock, in both of which fissures Professor Bonney found ice on July 23d.
