sils. Six days were spent collecting at Cercado, the party stop- 

 ping at the house of Senor Jose Fraden, a very intelligent and 

 kindly man. He said there were many badly disposed people 

 (muc/10 malo gente) in the neighborhood and therefore was so good 

 as to send the young man of the house with the party and with 

 the guide as a protection. 



Three fossiliferous cliffs were found above Cercado and one 

 or two below. Large collections were made from these bluffs. 

 This occupied about a week's time. A trip was also made to the 

 Rio Amina as far as Hato Vie jo on the Amina (14 on the sketch 

 map); and thence to Potrero (15 on map). At Potrero Ostrea 

 and Spondylns were found, but badly preserved. 



Returning to Cercado the work was interrupted by a ten 

 foot rise of the Rio Mao. Indeed, even before this rise the cur- 

 rent had been very swift and the fording deep. Politically also 

 the situation was becoming daily more dangerous, especially on 

 approaching nearer to Santiago, where Desiderio Arias, the leader 

 of the revolution, was entrenched. It was deemed best to take 

 the fossils secured back to Monte Cristi and so get them safely 

 out of the interior to the port, then to obtain supplies that were 

 needed, and try a fresh start for Santiago. 



The furthest point reached up the Mao was Hato Viejo (the 

 one mentioned by Gabb, not Hato Viejo on the Amina); and on 

 the summit of the last accessible bluff, which rises some 300 feet 

 above the river at that point, the aneroid read 650 feet, but we 

 feel little confidence in this and give it only as approximate. 

 There is a splendid view from the top of this cliff, looking south- 

 ward, of the broken foothills of the main range. Gabb men- 

 tions four terraces here. Our party saw one very striking high 

 level terrace about 700 feet, and a lower less pronounced terrace 

 about 640 feet, giving an approximate difference of 50 feet. 

 There were also other levels at a lower altitude and to the south- 

 west, but they were ill-defined. 



The party returned along the outward trail as far as Las
