 of them,&quot; replied Wallace. &quot; In my mind, only one 

 thing possible accounts for their position. You 

 observe they appear to be about level with each 

 other. Well, once the canon floor ran along that 

 line, and in the ages gone by it has lowered, washed 

 away by the rains.&quot; 



This conception staggered us, but it was the only 

 one conceivable. No doubt we all thought at the 

 same time of the little rainfall in that arid section of 

 Arizona. 



&quot; How many years? &quot; queried Jones. 



&quot;Years! What are years?&quot; said Wallace. 

 &quot; Thousands of years, ages have passed since the 

 race who built these tombs lived.&quot; 



Some persuasion was necessary to drag our scien 

 tific friend from the spot, where obviously helple 

 to do anything else, he stood and gazed longingly

 fissures, caverns and ruins had to be passed by, for 

 lack of time. 



Still, a more interesting and important discovery
