Hunting Horned Dinosaurs 83 



armed with smaller and blunter ones. The or- 

 bital horns are round and conical, not much over 

 six inches in length, .while the one on the bridge 

 of the nose is over a foot long. 



Now, with the rapidity of thought we will re- 

 turn to our work-shop. When George prepared 

 the head of this fine specimen, I found it was the 

 exact size of the one I found in 1913. I there- 

 fore took a cast of the parts that were missing in 

 mine. In order to accomplish this, I covered 

 the front of the head with lard oil and then with 

 molding wax, being careful to make it in sections 

 so it would come off and be heavy enough to pre- 

 vent distortion. When all was ready and we had 

 colored our plaster to resemble the fossil bone 

 no small task, by the way, as we had to learn to 

 mix colors as well as do the work of a sculptor 

 with wax. Then the mold is separated from the 

 skull and stuck together, plaster strengthened 

 with dextrine is poured into it, and on hardening 

 I got an exact fac-sirnile of the original speci- 

 men. This I fastened to my skull in which these 

 parts were missing, and this gave us two speci- 

 mens for public exhibition. Otherwise we could 

 not have exhibited this dinosaur, as it would not 

 have done to guess at these missing parts, as the 

 early scientists were in the habit of doing. Now 

 we can point to the complete specimen should 

 anyone doubt the truthfulness of the restoration. 

 All through the Belly River Series of rocks are 

 bone-beds. There are two below Steveville, one
