THE LIVING STRUCTURES 141 



become hard and then cements them together. These 

 pellets are as large as small peas and one bee has been 

 known to prepare as many as one hundred and fifty in a 

 single day." 



I have watched the action of bees, beetles, spiders and 

 ants and other insects and must say that their actions 

 show intelligence of a very high degree and will refer to 

 many of their acts later on, which are simply wonderful. 

 You might say if the insect building cells are so intelli- 

 gent, why do they not build larger and stronger struc- 

 tures like ourselves or other animals. Upon that point 

 we need but consider all the structures produced in the 

 past ages, like the Mastodon and thousands of others that 

 went too far in that direction and got the structures too 

 large. Their skeletons are now conclusive evidence to 

 the insects and ourselves that size is not necessarily a 

 quality that spells success. The size must be considered 

 in the light of permanent and perpetual existence on this 

 planet, as well as the other features. I quote the follow- 

 ing from the Scientific American, which is very signifi- 

 cant : "Rarely is it safe to speak of anything as ultimate 

 in prehistoric life, but there is little doubt that the 

 American Museum now exhibits a skeleton of the largest 

 flesh-eating animal that has ever lived. This is Tyran- 

 nosaurus, the tyrant lizard, a dinosaur that lived during 

 the close of the Cretaceous period. It was one of the very 

 last expressions of its race and, judged by size and struc- 

 ture, was king of its kind. An idea of its immense size 

 can be formed from measurements of the skeleton, 47 

 feet in length, and, as mounted, 18^2 feet in height. When 

 fully erect this animal would have reached a height of 20 

 feet. 



"Larger herb-eating dinosaurs have been found in 

 America and East Africa in older rocks of Jurassic or
