With the DFO&rsquos blessing I take another elephant ride in the afternoon. Unlike the ride in the morning this one is deep within the core area of the sanctuary there are no roads and no tourists. And no effete howdahs either. This time I am riding a patrol elephant practically bareback. Robi Biswas Sharma, the mahout, was born in Hollong and has lived in the sanctuary all his life. His elephant, Champakali, is the ultimate ATV. She effortlessly negotiates rivers, taking on four-foot drops along muddy banks and climbing back up. On occasion we saunter on dry riverbeds sometimes the terrain is dense jungle with thick vines hanging down to a verdant undergrowth of ferns. But mostly, we float through acres of elephant grass. As far as the eye can see is a vast pristine savannah with scattered trees, extending to a forest-line at the horizon. Here, finally, is rhino country. Robi points out giant piles of rhino dung, some nearly three feet high (how did the last individual scale this pile without flattening it). In this neighbourhood, a neat array of egrets floating above the vegetation is a dead giveaway. The birds ride on the rhino&rsquos back keeping the rhino skin bug-free and their own bellies full. As we approach, the animal pauses grazing, lifts its head and cocks its ears. It does not really see much due to poor vision, and often goes right back to grazing. A grazing rhino cuts an idyllic, nearly bovine figure. But it is really a two-tonne steel-plated tank that can do zero to 45 in a minute. I see this first-hand when we spot two rhinos getting into a conflict. In the five minutes it takes Champakali to get closer, the silent prairie echoes with squeals and grunts as one chases the other clear to the horizon.
