SNOW AND ICE.

these lines was arranged in 1874, the stones painted 
yellow, and their position carefully marked. When 
they came to the fall they disappeared for four 
years, after which some of them again emerged at 
the surface, and some of the central ones have 
reached the lower end of the glacier, which has re- 
treated some yards from the spot at which they were 
deposited. 
As in many of the most accessible glaciers, a 
gallery has been cut into the ice, and is well worth 
a visit. 
The exquisite curves into which the ice is melted 
by the eddying currents of air are very lovely. Again, 
one can easily trace the glacier grains especially if a 
little ink or other coloured fluid is rubbed over the 
surface of the ice, when it runs down between the 
grains, marking them out with dark lines. Each 
grain, moreover, shows very fine lines of crystallisa- 
tion, which are parallel in each grain, but differ in 
different grains. The chief attraction, however, is 
naturally the splendid blue colour of the ice, and the 
lovely pink complementary tints of the reflections from 
the surface.
