The scow grounded on some rocks in shallow rapids.

之后船在潜流里的石头上得以搁浅。

It took twenty men to sail and row a five-ton scow up the river at a speed of from ten to twenty miles a day.

需要二十个人才能以每天 10 到 20 英里的速度航行和划一艘 5 吨重的平底船逆流而上。

Scows of from five to fifty tons were built at the towns along the rivers and piloted down the stream to the Crescent City.

在沿河的城镇建造了 5 到 50 吨的铲车，并沿着溪流行驶到新月城。

The men were eventually rescued the next morning and because it was too dangerous to try to remove the scow itself, it's been rusting there less than 2,000 feet from Horseshoe Falls ever since.

两名船员在次日上午获救，而船，由于移动它过于危险，就把它弃在了距霍斯舒瀑布不足2000英尺的地方。
