"Fire!"

A formidable report followed his order, and the blocks, shaken by the atmospheric commotion, were suddenly precipitated into the sea; the disturbance amongst the strata of the air had been sufficient to accomplish this.

"All steam on, Brunton! Straight for the pass, Johnson!"

The latter was at the helm; the brig, driven along by her screw, which turned in the foaming waves, dashed into the middle of the then opened pass; it was time, for scarcely had the Forward cleared the opening than her prison closed up again behind her. It was a thrilling moment, and on board there was only one stout and undisturbed heart—that of the captain. The crew, astonished at the manoeuvre, cried out:

"Hurrah for the captain!"

CHAPTER XIV

EXPEDITION IN SEARCH OF FRANKLIN

On Wednesday, the 23rd of May, the Forward had again taken up her adventurous navigation, cleverly tacking amongst the packs and icebergs. Thanks to steam, that obedient force which so many of our Polar sea navigators have had to do without, she appeared to be playing in the midst of the moving rocks. She seemed to recognise the hand of an experienced master, and like a horse under an able rider, she obeyed the thought of her captain. The temperature rose. At six o'clock in the morning the thermometer marked twenty-six degrees, at six in the evening twenty-nine degrees, and at midnight twenty-five degrees; the wind was lightly blowing from the south-east.

On Thursday, towards three in the morning, the Forward was in sight of Possession Bay, on the coast of America. At the entrance to Lancaster Strait, shortly after, the crew caught a glimpse of Burney Cape. A few Esquimaux pulled off towards the vessel, but Hatteras did not take the trouble to wait for them. The Byam-Martin peaks, which overlook Cape Liverpool, were sighted to the left, and soon disappeared in the evening mists, which also prevented any observation being taken from Cape Hay. This cape is so low that it gets confounded with the ice on the coast, a circumstance which often renders the hydrographic determination of the Polar seas extremely difficult.
