Naturalists say that within a short distance in this region may be found all the trees peculiar to the Amoor.

Some of them are three or four feet in diameter and very tall and straight.

The elm and larch attain the greatest size, while the ash and oak are but little inferior.

The cork-tree is two feet through, and the maackia--a species of oak with a brown, firm wood--grows to the diameter of a foot or more.
In summer the foliage is so dense that the sun's rays hardly penetrate, and there is a thick 'chapparel' that makes locomotion difficult.

Just below the Ousuree the settlers had removed the under growth over a small space and left the trees appearing taller than ever.
