 174 THE FUR COUNTRY. For some time not another word was spoken. All involuntarily turned towards the south, where the broken isthmus was situated ; but from their position they could only see the sea horizon on the north. Had Cape Bathurst been situated a few hundred feet more above the level of the ocean, they would have been able at a glance to ascertain the limits of their island home. All were deeply moved at the sight of Fort Hope and all its occupants borne away from all solid ground, and floating at the mercy of winds and waves. " Then, Lieutenant," said Mrs Barnett at last, "all the strange phenomena you observed are now explained ! " " Yes, madam," he replied, " everything is explained. The peninsula of Victoria, now an island, which we thought firm ground with an immovable foundation, is nothing more than a vast sheet of ice welded for centuries to the American continent. Gradually the wind has strewn it with earth and sand, and scattered over them the seeds from which have sprung the trees and mosses with which it is clothed. Rain-water filled the lagoon, and produced the little river ; vegetation transformed the appearance of the ground ; but beneath the lake, beneath the soil of earth and sand — in a word, beneath our feet is a foundation of ice, which floats upon the water by reason of its being specifically lighter than it. Yes, it is a sheet of ice which bears us up, and is carrying us away ; and this is why we have not found a single flint or stone upon its surface ! This is why its shores are perpendicular, this is why we found ice ten feet below the surface when we dug the reindeer pit — this, in short, is why the tide was not noticeable on the peninsula, which rose and sank with the ebb and flow of the waves ! " " Everything is indeed explained," said Mrs Barnett, " and your presentiments did not deceive you ; but can you explain why the tides, which do not aflTect us at all now, were to a slight extent per* ceptible on our arrival % " " Simply because, madam, on our arrival the peninsula was still connected by means of its flexible isthmus with the American continent. It offered a certain resistance to the current, and on its northern shores the tide rose two feet beyond low- water mark, instead of the twenty we reasonably expected. But from the moment when the earthquake broke the connecting link, from the moment when tlie peninsula became an island free from all control, it rose and sank with the ebb and flow of the tide; and, as we noticed together
