Nilgiris has a number of grassy undulating hills. They are divided by narrow valleys and swamps. W. Francis observes, the plateau is a true table land, its average height being very uniform. But there is not a square mile of level ground in the whole of it, its surface being broken by endless undulations which in places swell into considerable and distinct ranges".
