“Which, the view or the victuals?” asked Lewis. “Both,” cried the Professor, helping himself to another half-dozen sandwiches.
“Thank you—no more at present,” said Nita to the disappointed Slingsby, who placed the rejected limb of a fowl on his own plate with a deep sigh.
“Professor,” said Nita, half-turning her back on the afflicted artist, “how, when, and where be all this ice formed?”
“A comprehensive question!” cried the Professor. “Thank you—yes, a wing and a leg; also, if you can spare it, a piece of the—ah! so, you are right. The whole fowl is best. I can then help myself. Miss Gray, shall I assist you to a—no? Well, as I was about to remark, in reply to your comprehensive question, Mademoiselle, this basin, in which our Jardin lies, may be styled a mighty collector of the material which forms that great tributary of the Mer de Glace, named the Glacier du Talèfre. This material is called névé.”
“An’ what’s nevy?” asked Captain Wopper, as well as a full mouth would allow him.
“Névé,” replied the Professor, “is snow altered by partial melting, and freezing, and compression—snow in the process of being squeezed into ice. You must know that there is a line on all high mountains which is called the snow-line. Above this line, the snow that falls each year never disappears; below it the snow, and ice too, undergoes the melting process continually. The portion below the snow-line is always being diminished; that above it is always augmenting; thus the loss of the one is counterbalanced by the gain of the other; and thus the continuity of glaciers is maintained. That part of a glacier which lies above the snow-line is styled névé; it is the fountain-head and source of supply to the glacier proper, which is the part that lies below the snow-line. Sometimes, for a series of years, perhaps, the supply from above is greater than the diminution below, the result being that the snout of a glacier advances into its valley, ploughs up the land, and sometimes overturns the cottages. (See Note 1.) On the other hand the reverse process goes on, it may be for years, and a glacier recedes somewhat, leaving a whole valley of débris, or terminal moraine, which is sometimes, after centuries perhaps, clothed with vegetation and dotted with cottages.”
“This basin, or collector of névé, on whose beautiful oasis I have the felicity to lunch in such charming society (the jovial Professor bowed to the ladies), is, according to your talented Professor Forbes (he bowed to Lawrence), about four thousand two hundred yards wide, and all the ice it contains is, farther down, squeezed through a gorge not more than seven hundred yards wide, thus forming that grand ice-cascade of the Talèfre which you have seen on the way hither. It is a splendid, as well as interesting amphitheatre, for it is bounded, as you see, on one side by the Grandes Jorasses, on the other by Mont Mallet, while elsewhere you have the vast plateau whence the Glacier du Géant is fed; the Aiguille du Géant, the Aiguille Noire, the Montagnes Mandites, and Mont Blanc. Another wing, if you please—ah, finished? No matter, pass the loaf. It will do as well.”
The Professor devoted himself for some minutes in silence to the loaf, which was much shorn of its proportions on leaving his hand. Like many great men, he was a great eater. The fires of intellect that burned within him seemed to require a more than ordinary supply of fuel. He slept, too, like an infant Hercules, and, as a natural consequence, toiled like a giant when awake.
Little Gillie White regarded him with feelings of undisguised awe, astonishment and delight, and was often sorely perplexed within himself as to whether he or Captain Wopper was the greater man. Both were colossal in size and energetic in body, and both were free and easy in manners, as well as good-humoured. No doubt, as Gillie argued with himself (and sometimes with Susan), the Professor was uncommon larned an’ deep, but then the Captain had a humorous vein, which fully counterbalanced that in Gillie’s estimation.
The philosophic urchin was deeply engaged in debating this point with himself, and gazing open-mouthed at the Professor, when there suddenly occurred an avalanche so peculiar and destructive that it threw the whole party into the utmost consternation. While removing a pile of plates, Gillie, in his abstraction, tripped on a stone, tumbled over the artist, crushed that gentleman’s head into Nita’s lap, and, descending head foremost, plates and all, into the midst of the feast, scattered very moraine of crockery and bottles all round. It was an appalling smash, and when the Captain seized Gillie by the back of his trousers with one hand and lifted him tenderly out of the midst of the débris, the limp way in which he hung suggested the idea that a broken bottle must have penetrated his vitals and finished him.
