1911 Encyclopædia Britannica (1911)
“ The summit of the Nilgiri hills is an undulating plateau, frequently breaking into lofty ridges and steep rocky eminences. The descent to the plains is sudden and abrupt, the average fall from the crest to the general level below being about 6000 ft., save on the north, where the base of the mountains rests upon the elevated land of Wynaad and Mysore, standing between 2000 and 3000 ft. above sea-level. The Ochterlony valley and Wynaad country consist of a series of broken valleys, once forest-clad throughout, but now studded with tea and coffee-gardens. ”
