Well-financed by Andrew Carnegie and by his own writings, Roosevelt's large party hunted for specimens for the Smithsonian Institution and for the American Museum of Natural History in New York.[224] The group, led by the hunter-tracker R.J. Cunninghame, included scientists from the Smithsonian, and was joined from time to time by Frederick Selous, the famous big game hunter and explorer. Participants on the expedition included Kermit Roosevelt, Edgar Alexander Mearns, Edmund Heller, and John Alden Loring.[225]
The team killed or trapped 11,400 animals,[224] from insects and moles to hippopotamuses and elephants. The 1,000 large animals included 512 big game animals, including six rare white rhinos. Tons of salted carcases and skins were shipped to Washington; it took years to mount them all, and the Smithsonian shared duplicate specimens with other museums. Regarding the large number of animals taken, Roosevelt said, "I can be condemned only if the existence of the National Museum, the American Museum of Natural History, and all similar zoological institutions are to be condemned".
