Once Frank and Muriel excitedly watched a snow-leopard stalking one of these big-horned sheep sixteen thousand feet above the sea-level . And in these heights they even saw an occasional lynx or wolf , generally only to be found in the highest elevations bordering on Tibet . Silver-haired _ langur _ apes , the white fringes around their black faces giving them a comic resemblance to aged negroes , awoke the echoes of the mountains with their deep booming cry ; while in the lower valleys little brown monkeys mopped and mowed from the trees at the fugitives as they passed . On one occasion Muriel , exhilarated by the keen , life-giving air , ran gaily on ahead of the others in a wood -- and came on a tiger enjoying its midday siesta . But the striped brute only uttered a startled `` Wough ! Wough ! '' like a big dog and dashed away through the undergrowth .
