to the osteologist, Mr. Frederic A. Lucas. It was a labor of enormous difficulty, re- quiring the highest order of knowledge. All of the parts of the skeleton not being at hand, it was necessary to supply the miss- ing bones, and this had to be done with scientific accuracy and not by guesswork. Of course, some small latitude of imagina- tion was allowable. The original bones were too heavy, too fragile and too precious to be employed in the restoration, which is built of wood, wire cloth and papier mache. Mr. Lucas and his assistants have been engaged on the job for three months, and now the skeleton of the fossil cetacean is finished and ready to be packed up for transportation. Nobody would imagine that it was artificial, so natural do the "bones" look. It is a huge affair. If it were set up in an ordinary house, with the nose of the creature at the front door, the end of the tail would stick out of the gate of the back yard. It is fifty feet long. But that is not very big for a zeuglodon, individuals of whose kind attain a length of seventy feet or more. There are stories of modern sperm whales as long as that, but nobody ever put a tape line on a specimen that was over fifty feet. Zeuglods in their time must have been exceedingly numerous, judging from the astonishing quantities of their remains that are dug up. The first specimen to attract scientific attention was found in Alabama by Dr. Harlan, in 1834. Along in the forties Judge Creagh was clearing a farm in the same state and came across so many of the bones that they were actually an obstacle to agriculture. To get rid of them, they were piled in heaps with brush and burned. The latest edition of Dana's "Geology" re- peats an old and quite erroneous statement to the effect that farmers in Alabama use the fossil bones of zeuglods for building stone walls. Though not so numerous as this yarn would imply, they are frequently dup up in the fields. One reason for the in- completeness of the remains is found in the great size of the animals. When a skeleton sixty or seventy feet long has lain buried near the surface of the ground for hun- dreds of thousands of years, rain is pretty sure to cut gullies across it, and carry away sections of it. What happens to be left is exposed to the disintegrating action of water and frost.
