This was precisely what Antoine meant to do, and did, but it was not until more than an hour had been lost that a safe bridge was found. When they had crossed, the configuration of the ice forced them to adopt a route which they would willingly have avoided. A steep incline of snow rose on their right, on the heights above which loose ice-grags were poised as if on the point of falling. Indeed, two or three tracks were passed, down which, probably at no distant period, some of these avalanches had shot. It was nervous work passing under them. Even Antoine looked up at them with a grave, inquiring glance, and hastened his pace as much as was consistent with comfort and dignity.
Soon after this the sun began to rise, and the upper portions of the snow were irradiated with pink splendour, but to our travellers he had not yet risen, owing to the intervening peaks of the Aiguille du Midi. In the brightening light they emerged upon a plain named the Petit Plateau, which forms a reservoir for the avalanches of the Dôme du Gouté. Above them rose the mountain-crest in three grand masses, divided from each other by rents, which exposed that peculiar stratified form of the glacier caused by the annual bedding of the snow. From the heights, innumerable avalanches had descended, strewing the spot where they stood with huge blocks of ice and masses of rock.
Threading their way through these impediments was a matter not only of time, but of difficulty, for in some parts the spaces between the boulders and blocks were hollow, and covered with thin crusts of snow, which gave way the instant a foot was set on them, plunging up to their waists the unfortunates who trod there, with a shock which usually called forth shouts of astonishment not unmingled with consternation.
“Here, then, we draw near to the grand summit,” said the Professor, pointing to the snow-cliffs on the right, “whence originates the ice-fountain that supplies such mighty ice-rivers as the Glacier des Bossons and the Mer de Glace.”
“Oui, Monsieur,” replied Antoine, smiling, “we draw near, but we are not yet near.”
“We are nearer to the summit however, than we are to the plain,” retorted the Professor.
“Truly, yes,” assented the guide.
“I should think no one could doubt that,” observed Slingsby, looking upwards.
“It looks quite near now,” said Lewis.
“Not so near, however, as you think, and as you shall find,” rejoined the guide, as they resumed their upward march.
