Fishing, fowling.

捕鱼，打鸟。

The earliest examples were the fowling pieces that appeared in 16th-century Europe.

最早的是16世纪时出现于欧洲的鸟枪。

A river would not be one and the same river were it not for the fact that the water fowling in it is always changing, as are the river Banks and even the course of the river.

一条河流不会永远是这一条河流，不仅仅是因为它的河水总是不断变化，甚至河源和河道都在不断改变着。
