The wing, breast, andother bones are now fastened on by drilling holes trans-versely through the ends and running wires through andtwisting them (r, d). The skeletons of mammals, fishes, etc. are mounted inmuch the same manner. If large, they are supported oniron rods. The wire used must be composed of brass orcopper, as iron corrodes easily. The fleshy or cartilaginousparts of the feet should be removed, but not the outer orhorny portion of the bill. PREPARING SKELETONS. 75. CHAPTER VI. COLLECTING AND PRESERVING EGGS. No portion of natural history has received more atten-tion than the science of Oology; yet in very many casescollections of eggs are made in such a careless manner asto render them worthless, except as ornaments, on accountof the collectors not paying sufficient attention to identifi-cation and authentication. Let identification, then, be the collectors first care; lethim make it a rule never to take an egg or nest untilhe can surely tell to what species it belongs. The bestmethod of learning the name of the owner of the nest is toshoot her, especially by collectors who have had but littleexperience in studying birds; while the more practisedornithologist can generally tell at a glance, if the bird islarge, what it is. While collecting the eggs of the War-blers and other small birds, the most ex
