124 Another Strange Homed Dinosaur 



on it nearly all one winter cleaning off the bog- 

 iron that covered it completely. If you will no- 

 tice closely the rough skull, especially with a 

 glass, you will see the bones were fractured in 

 aU directions. The first thing I had to do, was to 

 fasten these fragments securely in their places, 

 so I could remove the iron rust that clung firmly 

 to them. After many experiments with shellac, 

 I found a thin solution of ambroid was the most 

 satisfactory. It would penetrate better than 

 shellac, and when dry, was hard as the flinty 

 rock itself. If any of the fragments broke loose 

 under the tools I used, I must filU them again 

 and again and wait twenty-four hours or more 

 for the cement to set firmly. You will notice the 

 lower jaw and crest seem rather smooth com- 

 pared with the rest of the skull, and they are, 

 because they are restored in plaster, from the 

 complete skull Charlie found. The crest was 

 chiefiy prepared by Levi. This was done while it 

 was still in the plaster jacket. It was first re- 

 stored in moulding wax, copying exactly the per- 

 fect crest. I mean by that, the wax on the jacket 

 was manipulated by my son until it was a fac- 

 simile of the original parts so as to be beyond 

 criticism. Then a cast was made in plaster of 

 the wax model, the wax taken away, and the 

 place it occupied replaced with plaster colored 

 as near the original color of the bone as possible, 

 to prevent a discord, or lack of harmony in the 

 completed skeleton. You see, then, we must be
