384 SMITH. 



have been taken from one hole and 5,000 from another. The owner of 

 one of the mines' said he had taken 2,000 tael (2,800^* pesos) from it 

 in 16 years, but he did not state how many men he worked. The report 

 of the Spanish Government gives the production for one year at 600 taels 

 (840 pesos). 



Ickis ^^ published a report interesting for the confirmatory evidence 

 of vulcanism in this region and for the data he obtained regarding the 

 country farther to the south in the vicinity of Sevilla, which is on the 

 upper waters of the Pulangui much farther in the interior than either 

 Abella or Nichols ever reached. 



I have already discussed the physiography of the Tagoloan Kiver in 

 the chapter on that topic. The main point of interest in this connec- 

 tion is the fact that after the gorge of the Tagoloan is passed, some 25 

 kilometers back of Agusan, the country opens and is much gentler in 

 topography. 



Ickis found only alluvial land covered with talaliih (Saccharum spon- 

 taneum L.) in the region of the Pulangui Eiver. This land contains a 

 great amount of gravel and, according to Ickis, is of considerable area. 

 He thought that the country would be well adapted to dredging opera- 

 tions. He says : 



The gravel beds along the Pulangui River are extensive, and promising colors 

 ■ were obtained by washing the surface near Sevilla in gold pans. It is believed 

 that these gravels are worthy of careful investigation by prospectors who have 

 testing machines, or who are equipped to sink test pits. The head waters of 

 this river also afford a virgin field, since no prospector or miner has ever been 

 known to visit the region. Gold is known to occur in the river gravels and the 

 rock is of a nature favorable for the formation of mineral deposits. At the present 

 time transportation is a difl&cult problem, but it is expected that a wagon road 

 will soon be constructed from Agusan to the Pulangui River." 



Before closing the discussion concerning this district I will refer once 

 more to Catarman Volcano on the Island of Camiguin. 



The mountain and volcano of Catarman on the Island of Camiguin. — 

 In Part II of this work I gave some excerpts from a report by Father 

 Maso, S. J., relating to Catarman Volcano. Since the preparation of 

 that manuscript some interesting water color sketches were found in 

 Catarman by Mr. Dean C. Worcester, Secretary of the Interior, and 

 kindly loaned to the Bureau of Science by him. These were made on 

 the spot by an old Spanish resident (Plates III and IV). 



I have only one sample of the rock from the mountain, collected by 

 Mr. H. D. McCaskey, formerly chief of the Mining Bureau. The rock 

 is a grayish, vesicular lava with numerous glassy feldspar and a few ferro-
