关于你这个问题,我思考了很久.我也搜了其他网友的回答,我都不能感到满意.
他们似都有意或无意地回避了为什么这里不可以用from which的问题.
接下来是我的回答
1.首先我们要了解英语中的一种语法现象：介词连用的问题.
例如：他从床下找到了十块钱
He found 10 yuan from under the bed.
这里from和under缺一不可
from自不必说,under缺了的话句意不明（不能提先是从床下,也可能在床上）
再给你两个例句供参考：
两个介词是可以连用的,在语法中叫做"二重介词"比如:
He jumped from behind the tree.
He waited there until after 8:00.
2.明白了这个现象你的问题就不难解决
我还是先带你看一个教材中的句子
We climbed up a mountain from where we had fantastic views.
这的确是定语从句,可不可以用from which?
如果用from which,那我们还原一下we had fantastic views from the mountain.
从山可以看到美景,我在山脚下可以看到吗?答案是否定的.
应该是we had fantastic views from on he mountain.
which可以指代on he mountain吗?显然不能,这时地点状语需要where指代.
讲到这里我想你应该差不多明白了.
最后来看你的句子
His head soon appear out of one of the second windows ,form where he could see no thing but trees.
先行词是window
还原回去是he could see no thing but trees from the window（从窗户他什么都看不到）
应该是从窗户外面（这个地方）他只能看到树.
he could see no thing but trees from out of the window the window
where指代out of the window
可惜你是匿名否一定hi你.因为确实不好解释.还有疑问就站内或者hi'我吧
