The word "auction" usually conjures  images  priceless art, fine wines or celebrity memorabilia. It rarely makes us think  a near-threatened species  rhinoceros. However, those rich enough to splash  in excess of $10 million can bid  1,993 white rhinos on May the 1st, which is International Save the Rhino Day. The majestic beasts are being sold  multi-millionaire conservationist John Hume, a South African entrepreneur. He started a rhino breeding project  about 200 animals 30 years ago. He managed to increase his stock  the animals ten-fold. Mr Hume is also selling the 8,500-hectare ranch 100 miles south-east  Johannesburg where the rhinos live.
Mr Hume's ranch is home  more than 10 per cent  the world's total rhino population. Hume has spent $150 million  his personal fortune  increasing rhino numbers, but can no longer afford to maintain the creatures. His expenses include vets' bills, security guards to keep poachers  bay and a helicopter  air patrols. He told reporters: "I've used all my life savings spending  that population of rhinos for 30 years and I finally ran  of money. I'm hoping that there is a millionaire that would rather save the population  rhinos from extinction than own a super-yacht." Hume lamented that: "Rhinos are underdogs. They stand the least chance  surviving poaching."
