At this business I think I was quite skillful, not having forgotten my experience years before on the Champlain canal.

在这行我觉得我很熟练，没有忘记我多年前在尚普兰运河上的经历。

During the winter I was employed with others repairing the Champlain Canal, on that section over which William Van Nortwick was superintendent.

冬天， 我和其他人一起受雇修复尚普兰运河，威廉·范·诺特威克 (William Van Nortwick) 负责这一段的管理。
