Jock Of The Bushveld by Sir Percy Fitzpatrick ( Chapter 18) ( Page 5 ) Snowball and Tsetse

Snarleyow was with us--I had left Jock at the waggons fearing that we would get into fly country on the Umbelusi--and the bank was too high and too steep for him; he huddled up against it half supported by reeds, and whined plaintively. To our relief Snowball faced the jump quite readily; indeed, the old sinner did it with much less effort and splash than the bigger Tsetse. But then came an extremely unpleasant spell.  Snowball got a scare,
because Hall in his anxiety to get me out rushed up to him on the warty side to get the reins off; and the old ruffian waltzed around, dragging Hall through the thorns, while Snarleyow and I waited in the water for help. At that moment I had a poorer opinion of Snowball and Snarley than at any other I can remember.  I wished Snarley dead twenty times in twenty
seconds.  Crocodiles love dogs; and it seemed to me a million to one that a pair of green eyes and a black snout must slide out of the water any moment, drawn to us by those advertising whines!  And the worst of it was, I was outside Snarley with my white legs gleaming in the open water, while his cringing form was tucked away half hidden by the reeds. What an age it seemed!  How each reed shaken by the river breeze caught the eye, giving me goose-flesh and sending waves of cold shudders creeping over me!  How the cold smooth touch of a reed stem against my leg made me want to jump and to get out with one huge plunge as the
horses had done!  And even when I had passed the struggling yowling Snarley up, the few remaining seconds seemed painfully long.  Hall had to lie flat and reach his furthest to grip my hand; and I nearly pulled him in, scrambling up that bank like a chased cat up a tree.
When one comes to think it out, the bank must have been nine feet high. It was mighty unpleasant; but it taught us what a horse can do when he puts, his back into it!
