ARMADILLOS 83 



through the same layer but not immediately adjacent were 

 numerous limb bones which seem to belong to the same 

 form, judging from their excessive size and general elephan- 

 tine characteristics. This was the first time more than teeth 

 of this form had been found, and things grew exciting; so 

 our date for leaving was set ahead three more days. Next 

 day Billy found another smaller Pyrotherium skull, and 

 three other sorts of skulls ; then Shumway located a pair of 

 jaws and the limb bones of a small animal which has all 

 the appearance of being one of the early horses from the 

 Eocene of North America. We then gave up fixing a 

 date for closing work. 



During these days the horses began to bother us by 

 wandering off. The first time was Monday afternoon, when 

 we searched until dark and then returned to camp to find 

 that they had come in of themselves. Next morning they 

 were four miles away, and that night we did not find them 

 at all. Wednesday morning they were five miles away, 

 and when they have to be located by tracking them it takes 

 a great deal of time. This sort of trouble is typical when 

 traveling in such a country, where every second man one 

 meets, asks if you have seen a red, white, or black horse 

 with such and such peculiarities. 



When it was evident that we still had a week's work ahead 

 of us, we loaded all the specimens in camp into the wagon 

 and Saturday morning I started for Port Visser. For the 

 first four miles we made a new trail in order to escape 

 the heavy sand on the first slopes of the hills. With the 

 wagon box full of fossils it was slow traveling, but I made 

 clear across the pampa and camped on a spring under the 

 further side, reaching the Port about ten the next morning. 

 The rest of the day was occupied stowing away my stuff, 

 getting new supplies and visiting, during which I agreed to 

 sell Mr. Potts my wagon and harness, to be delivered in 

 Comodoro Rivadavia when we were through with them. 



With an early start Monday morning I pushed clear across
