 piles, and perhaps lost. 



In the early morning we reached Quimili, at which place

 numerous stops but no towns of any importance. At 

 2.30 P. M., the train halted at Avia Terai, and we were soon 

 encamped in the rear of one of the two huts comprising 

 that station. 



About all we could see from our abode was an immense 

 area covered with tall weeds, surrounded by dense forest. 

 Sand-flies, called polvorinos, filled the air like flecks of dust
