One book below was bought for its cover and illos, the Ibex story; one excellent series, published by Putnam's in Boston in the early years of the last century, is made up of good natural history books, but I started collecting them only after I bought three separately, and realized that the volumes I nostalgically remembered from my childhood days at the Ames Free Library in Easton, Mass. all had gilt images embossed on their covers.
abeBooks for more realistic prices), which has a golden warthog; The Tribes on my Frontier, "EHA's" accounts of birds and beasts who were human commensals in Colonial India, and doubtless still are today (those little things are what Kipling called "muskrats" in "Rikki Tikki Tavi", a kind of smelly house shrew), and the Ibex in a slightly sub- Seton but beautifully illustrated biography of that animal. The Rod in India, which I got from the late Datus Proper in Bozeman and which contains one of my favorite chapter titles anywhere, the nearly self- parodic "Circumventing the Mahseer", also has one of my favorite cover emblems, said mahseer hanging from a tree.
The second edition of Patterson's Man Eaters of Tsavo has a splendid but unexplained sabertooth; John Lockwood Kipling, father of Rudyard and the keeper of the "Treasure House" museum in Kim, has a rather more understandable elephant.
