兽皮

The barterer exchanged trinkets for the natives furs.

货贩子用小件饰物换取土著兽皮。

In some tropical regions small boats used to be made of skins stretched over a wooden frame.

过去有些热小船是用兽皮绷在一个木头框子上造成。

Do a few withered grass, feather or hide lid to be on scree next, make it an incubative nest.

然后弄一些枯草、羽毛或兽皮盖在小石子上，做成了一个孵。
