Vindhya mountains; a red gravelly undulating formation had given place
to basaltic rocks. They passed from groups of _mhowa_ trees and left
behind a wide shallow stream, its bed dotted with pools fringed by
great _kowa_ trees, and its banks lined by a thick green cover of
_jamun_ and _karonda_. Thorny _babul_ thrust their spiked branches out

the blue tint to the white moons in his finger nails. Barlow
shuddered. Why contemplate the matter at all--it was impossible. Nana
Sahib had named the barrier when he had spoken of _varna_, meaning
