80 Hunting Horned Dinosaurs 



four papers on the Creation of the world, each 

 one was different and each man thought he was 

 right. I have proved too often in my own ex- 

 perience in the field that I was mistaken, to doubt 

 that other scientific men might be also. I could 

 write a book about the mistakes of scientific men 

 but will not burden my pages with them except 

 as I discover facts absolutely different from those 

 commonly accepted, as in the case of my Chasmo- 

 saurus under discussion. In the past men have 

 been too anxious to publish results before com- 

 plete skeletons have been found and almost in- 

 variably, when one is found, it does not bear out 

 in its own person the expectations of their 

 authors. 



This field, so rich in material, in which we get 

 the skin impressions, as well as complete skele- 

 tons enables us to speak "as one having author- 

 ity" about them. Here then, although we have 

 an animal with limbs of equal length, the body 

 was covered with thin scales arranged like mo- 

 saic-work in a pavement. Without much doubt 

 the skull had been subjected to great pressure 

 for many ages. The rock in which it was em- 

 bedded has been lifted some twenty-five hundred

 mud at the bottom of the lake. Mr. Lambe, the 

 Vertebrate Paleontologist of the Geological Sur-

 osaur Chasamosaurus, on account of the great 

 chasms or gaps cut into the crest and skull. As
