Those reports from the Shannon and the Helvetia had slightly exaggerated its dimensions, and I put its length at only 250 feet.

我随便地观察了一下。山农号和海尔维地亚号两船的报告对它的体积有些夸张，我估计一下，它不过二百五十英尺长。

This labour so rough at first sight is one of the industries which most surprises the traveller who penetrates for the first time the mountains which separate France and Helvetia.

这种乍一看如此艰苦的工作是最让第一次穿越分隔法国和赫尔维蒂亚的山脉的旅行者感到惊讶的行业之一。
