树深 meaning in Chinese

tree depth

In this frame of thankfulness , i went home to my castle , and began to be much easier now , as to the safety my circumstances , than ever i was before ; for i observ d , that these wretches never came to this island in search of what they could get ; perhaps not seeking , not wanting , or not expecting any thing here ; and having often , no doubt , been up in the cover d woody part of it , without finding any thing to their purpose
我比以往任何时候都感到自己的住所安全可靠，因而心里也宽慰多了。因为我看到，那些残忍的食人部落来到岛上并不是为了寻找什么他们所需要的东西他们到这儿来根本不是为了寻求什么，需求什么或指望得到什么。因为，有一点是毫无疑问的：那就是他们一般在树深林密的地方登岸后，从未发现过任何他们所需要的东西。
