"Fire!" called out Johnson, and at once the electric spark was sent along the lines right into the keg of powder. A formidable explosion ensued; the house was shaken as if by an earthquake, and the walls cracked asunder. Hatteras, Altamont, and Bell hurried out with the guns, but they might spare their shot, for four of the bears lay dead, and the fifth, half roasted, though alive, was scampering away in terror as fast as his legs could carry him.
"Hurrah! Three cheers for Clawbonny," they shouted and overwhelmed the Doctor with plaudits and thanks.
The prisoners were free, and their joy found vent in the noisiest demonstrations. They employed the rest of the day in repairing the house, which had suffered greatly by the explosion. They cleared away the blocks piled up by the animals, and filled up the rents in the walls, working with might and main, enlivened by the many songs of old Johnson.
Next morning there was a singular rise in the temperature, the thermometer going up to 15° above zero.
This comparative heat lasted several days. In sheltered spots the glass rose as high as 31°, and symptoms of a thaw appeared.
The ice began to crack here and there, and jets of salt water were thrown up, like fountains in an English park. A few days later, the rain fell in torrents.
Thick vapour rose from the snow, giving promise of the speedy disappearance of these immense masses. The sun's pale disc became deeper in colour, and remained longer above the horizon. The night was scarcely longer than three hours.
Other tokens of spring's approach were manifest of equal significance, the birds were returning in flocks, and the air resounded with their deafening cries. Hares were seen on the shores of the bay, and mice in such abundance that their burrows completely honeycombed the ground.
The Doctor drew the attention of his companions to the fact, that almost all these animals were beginning to lose their white winter dress, and would soon put on summer attire, while nature was already providing mosses, and poppies, and saxifragas, and short grass for their sustenance. A new world lay beneath that melting snow.
But with these inoffensive animals came back their natural enemies. Foxes and wolves arrived in search of their prey, and dismal howls broke the silence of the short night.
