although it may have attained the considerable length of twenty- 

 five feet. 



STEGOSAURTJS. Another of the Deinosaurs is named the Stego- 

 saurus, and is represented on Plate VII. This is the Plated Lizard, 

 protected, as the illustration shows, by spines and plates of bone 

 along its back. A skeleton of a Stegosaur found in Jurassic strata 

 in the neighbourhood of the Rocky Mountains shows a length of 

 twenty-five feet. The fore-legs are shorter than the hind limbs : 

 the former, however, were strong, although the remarkable size 

 and power of the hind-leg bones indicate their more extensive use. 

 The animal may have used these hind limbs and its tail as a kind 

 of tripod upon which to rest or support itself. Some of the plates, 

 already referred to, are two to three feet in diameter. These 

 remains are fully described and explained by the Rev. H. N. 

 Hutchinson in his Extinct Monsters and Creatures of Other Days. 



BRONTOSATJRTTS. The Brontosaurus was another of the Deino- 

 saurs. It was a huge beast which may have weighed anything 

 from twenty to thirty or mofe tons. Its remains have been dis- 

 covered in the Jurassic rocks of North America; they indicate an 

 animal from fifty to sixty feet long with a shortish, thick body, a 

 short, small-brained head on a long neck, and a long tail. Its feet 

 were of great size; they have left impressions nearly a yard square 

 in area. It had no bony plates as a protection to its body, such as 

 the Stegosaurus possessed, and it must have used its powerful tail 

 for aggressive or defensive purposes. It was a vegetarian. Its 

 remains are usually found where it had become bogged. We can 

 quite understand that an animal so bulky and heavy would have 

 difficulty in negotiating bogs. Mr. Henry R. Knipe, in his Nebula 

 to Man, speaks of the Brontosaurs in these terms 



" But forms surpassing Stegosaurs are seen, 

 In point of size, and of as weird a mien. 

 Some here there are that look like Plesiosaurs 

 With elephantine legs, as on all fours 

 They creep along. And some among the band 

 From nose to tail-end eighty feet command. 

 Some twenty tons a monster maybe weighs, 

 And woe to him if into bogs he strays, 

 For going there, for ever there he stays. 

 Small headed are these Brontosaurs, since named, 

 Although in trunk and limb they huge are framed. 

 Quite simple are their tastes. The trees and plants 

 Afford them all they need for sustenance."
