earth movements as indicated by the present folded condition of 

 these sediments. 



One would get the impression from von Drasche that con- 

 siderable quantities of plant remains are to be found in the marl 

 beds. I found none in the marl, but all were in the tuff beds. 

 I saw no schist in that part of the area I explored. 



ECONOMIC GEOLOGY 



The economic portion of this report will of necessity be brief. 

 The semiwild state of most of the territory and the comparatively 

 untutored condition of the people, of course, precludes any but 

 the most rudimentary utilization of the mineral resources. In 

 the following discussion I shall consider not only the useful 

 minerals known to exist but some possibilities as well. 



NONMETALS 



Clay products. — There are undoubtedly many localities within 

 this territory where both residual and transported clays can be 

 obtained. Pottery making is here, as throughout the Philippines, 

 a household industry. The chief locality for its manufacture 

 is at the town of Samoqui, just across the river from Bontoc. 

 The clay is very poor and sandy and burns red. There is some 

 attempt at decoration, and there is a slight glaze given to the 

 pots by the use of resin, if I am correctly informed. This indus- 

 try has been described by Jenks." 



On the Bontoc side a fair grade of red brick is made by Igorots 

 under the superintendence of Americans. All of the public build- 

 ings of the capital of the province have been constructed of 

 this brick. The industry was started by John Early, formerly 

 a school-teacher stationed at Bontoc. The effect of these brick 

 structures is a very pleasing one. Apparently there have been no 

 earthquakes of sufficient importance to cause any damage, and 

 with the exception of this danger this type of construction seems 

 to be excellently adapted to the country. 



Sand-lime brick could easily be made in many localities in 

 this section. The principal cost would lie in the generation of 

 steam, and the manufacture might not be economical on that 

 score. 



Coal. — Thin streaks of coal have been reported from various 

 places in Mountain Province, but I have not seen any that 

 promise to be of commercial value. I believe that the changes
