 ern form, of which we had already shot specimens near its 

 northern, or at least north-eastern, limit. The distinction 

 proved sharp. 



On the day in question we breakfasted at six in the 

 morning, and were off immediately afterward; and we did 

 not eat anything again until supper at quarter to ten in the

 afternoon. Hour after hour we plodded across the plain, 

 now walking, now riding, in the burning heat. The withered 

 grass was as dry as a bone, for the country had been many

 to a bend in a little river, where flat shelves of limestone 

 bordered a kind of pool in the current where there were
