142 THE FORMS OF WATER IN 



we assail the Riffelhorn on its upper side. It is capital 

 •ock-practice to reach the summit; and from it we 

 command a most extraordinary scene. 



357. The huge and many-peaked mass of Monte 

 Rosa faces us, and we scan its snows from bottom to 

 top. To the right is the mighty ridge of the Lyskamm, 

 also laden with snow; and between both lies the 

 Western Glacier of Monte Rosa. This glacier meets 

 another from the vast snow-fields of the Cima di Jazzi ; 

 they join to form the Gorner glacier, and from their place 

 of junction stretches the customary medial moraine. 

 On this side of the Lyskamm rise two beautiful snowy 

 eminences, the Twins Castor and Pollux; then come 

 the brown crags of the Breithorn, then the Little Mat- 

 terhorn, and then the broad snow- field of the Theodule, 

 out of which springs the Great Matterhorn, and which 

 you and I will cross subsequently into Italy. 



358. The valleys and depressions between these moun- 

 tains are filled with glaciers. Down the flanks of the 

 Twin Castor comes the Glacier des Jumeaux, from Pollux 

 comes the Schwartze glacier, from the Breithorn the 

 Trifti glacier, then come the Little Matterhorn glacier 

 and the Theodule glacier, each, as it welds itself to the 

 trunk, carrying with it its medial moraine. We can 

 count nine such moraines from our present position. 

 Ajid to a still more surprising degree than on the Mer 

 de Glace, we notice the power of the ice to yield to 

 pressure ; the broad neves being squeezed on the trunk
