sacerdotal order; but whether the reigning classes whO; 

 withheld their knowledge from the common people for 

 selfish purposes were annihilated by an uprising of the ser- 

 vile hordes or by an outside invasion, or whether some 

 great cataclysm of nature extinguished the progress of ages 

 at a stroke, may forever remain a secret. 



The bird hfe around San Agustin was varied and abun- 

 dant. Trees were in blossom, especially one with a feath- 

 ery, pinkish flower (Mimosa), and to this scores of hummers 

 came. One species had a slightly curved bill and was green 

 in color, with a patch of deepest purple on the throat; an- 

 other of a blue color had tail-feathers six inches long. la 

 the ravines there were many chachalacas that kept up a

We scouted the forests daily, confining our search to the

 stream that joins the Magdalena a short distance below. 

 Great precipices flank its sides and the water rushes through 

 dark, narrow gorges. Everywhere the river-bed is dotted 

 with great boulders against which the water dashes with a
