The shell was fired and exploded high up on the face of the crags. The effect was startling. The explosion brought down tons of the frosty marble. The débris fell like blocks of iron that rang with a piercing cry on the ice-bound breast of the ocean. Millions of sea-fowl of every conceivable variety darkened the air. Their rushing wings sounded like the hissing of a tornado. Thousands were killed by the shock. A detachment of sailors under First Officer Renwick brought in heavy loads of dead fowl for a change of diet. The food, however, proved indigestible, and made the men ill.
We resolved, as soon as the sun had mounted the heavens from his midnight declension, to retrace our course somewhat and discover the cause of the terrible outcry of the night. We had been sailing for weeks along the southern ice-foot that belonged to the interminable ice hills which formed an effectual barrier to the pole. Day after day the Polar King had forced its way through a gigantic floe of piled-up ice blocks, floating cakes of ice, and along ridges of frozen enormity, cracked, broken, and piled together in endless confusion. We were in quest of a northward passage out of the terrible ice prison that surrounded us, but failed to discover the slightest opening. It had become a question of abandoning our enterprise of discovering the North Pole and returning home again or abandoning the ship, and, taking our dogs and sledges, brave the nameless terrors of the icy hills. Of course in such case the ship would be our base of supplies and of action in whatever expedition might be set on foot for polar discovery.
About six o'clock in the morning of the 20th of July we began to work the ship around, to partially retrace our voyage. All hands were on the lookout for any sign of such a catastrophe as might have caused the midnight commotion. After travelling about ten miles we reached the creek where the bear had been killed the day before. The man on the lookout on the top-mast sung out:
"Creek bigger than yesterday!"
Before we had time to examine the creek with our glasses he sung out:
"Mountains split in two!"
Sure enough, a dark blue gash ran up the hills to their very summit, and as soon as the ship came abreast of the creek we saw that the range of frozen precipices had been riven apart, and a streak of dark blue water lay between, on which the ship might possibly reach the polar sea beyond.
Dare we venture into that inviting gulf?
The officers crowded around me. "Well, gentlemen," said I, "what do you say, shall we try the passage?"
"We only measure fifty feet on the beam, while the fissure is at least one hundred feet wide; so we have plenty of room to work the ship," said the captain.
