I led the Canadian to the room where the Nautilus's men were putting on their diving suits. I informed the captain of Ned's proposition, which was promptly accepted. The Canadian got into his underwater costume and was ready as soon as his fellow workers. Each of them carried on his back a Rouquayrol device that the air tanks had supplied with a generous allowance of fresh oxygen. A considerable but necessary drain on the Nautilus's reserves. As for the Ruhmkorff lamps, they were unnecessary in the midst of these brilliant waters saturated with our electric rays.

我带加拿大人到诺第留斯号的船员穿潜水衣的房子中。我把尼德·兰的提议告诉船长，船长接受了。加拿大人穿上他的海中衣服，不久就跟他的工作同伴们一样准备好了。每人背上一个卢格罗尔的空气箱，由储藏库供应了大量的纯空气。对诺第留斯号的空气储藏库来说，这是大量的，然而是必要的支出。至于兰可夫灯，在这满是电光的明亮海水中间是没有用的。

After Ned was dressed, I reentered the lounge, whose windows had been uncovered; stationed next to Conseil, I examined the strata surrounding and supporting the Nautilus.

当尼德装备好了，我回到客厅，厅中的嵌板都开了，我站在康塞尔旁边，细看那顶住诺第留斯号的周围冰层。

Some moments later, we saw a dozen crewmen set foot on the shelf of ice, among them Ned Land, easily recognized by his tall figure. Captain Nemo was with them.

几分钟后，我们看见十多个船员下到冰地上，其中有尼德·兰，由于他的身材高大，很容易认出。尼摩船长跟他门在一起。

Before digging into the ice, the captain had to obtain borings, to insure working in the best direction. Long bores were driven into the side walls; but after fifteen meters, the instruments were still impeded by the thickness of those walls. It was futile to attack the ceiling since that surface was the Ice Bank itself, more than 400 meters high. Captain Nemo then bored into the lower surface. There we were separated from the sea by a ten-meter barrier. That's how thick the iceberg was. From this point on, it was an issue of cutting out a piece equal in surface area to the Nautilus's waterline. This meant detaching about 6,500 cubic meters, to dig a hole through which the ship could descend below this tract of ice.

在进行穿凿冰墙之前，他让人先做种种探测，保证工作是向顺利方面进行。很长的探测绳放人上下两面的冰墙。上面到了十五米，仍然被厚冰墙挡住，所以从上层冰板来厂凿是不成的，因为那就是四百米高的冰山本身。尼摩船长于是使人探测下部冰层的厚度。下部有十米厚的冰板把我们跟海水隔开。就是这片冰场有十米厚。自后就是要把冰场凿开一片，大小等于诺第留斯号从浮标线上来计算的面积。要凿开这么一个大孔，我们可以从这孔下到这冰地的下面去，那大约需挖掘六千五百立方米的冰。

Work began immediately and was carried on with tireless tenacity. Instead of digging all around the Nautilus, which would have entailed even greater difficulties, Captain Nemo had an immense trench outlined on the ice, eight meters from our port quarter. Then his men simultaneously staked it off at several points around its circumference. Soon their picks were vigorously attacking this compact matter, and huge chunks were loosened from its mass. These chunks weighed less than the water, and by an unusual effect of specific gravity, each chunk took wing, as it were, to the roof of the tunnel, which thickened above by as much as it diminished below. But this hardly mattered so long as the lower surface kept growing thinner.

工作立即开始，以十分坚持的顽强力气来进行。不是在诺第留斯号周围挖掘，这样可能带来更大的困难，尼摩船长是另外在距船左舷八米远的地方画了一个巨大的圆圈他的人员就在这圆圈的周围数处同时挖掘，不久，铁锨很有劲的打进了坚硬的冰，一块一块的冰从冰场凿开来。由于体重的新奇作用，这些冰块没有水重，它们于是飞跑到冰们顶上去了，这样一来，下面是减薄，上面就增厚了。但没关系，下层的冰总是削薄了。
