SMITH. 



Feldspar — Quartz and building stone. — These have all been sufficiently 

 commented upon in previous pages so that repetition is not necessary. 

 However, one thing should be mentioned, namely that analysis shows 

 the feldspar to be albite, the soda plagioclose. A physical examination 

 of the quartz grains proves this material to be suitable for glass manu- 

 facture, etc.

Prospecting and development work. — There are several prospectors in 

 this field, but only one organized company was doing any systematic 

 development work at the time of my visit. This is known as the "Ilocos 

 Mining Company," whose representative in the field is Mr. F. D. Bur- 

 dette, a man of considerable familiarity with Oriental mining operations, 

 geology and labor. Mr. Burdette's efforts are now being concentrated on 

 the asbestos of the Dungn-Dungan estate, and the manganese of Punta 

 Negra. The Punta Negra property is known as the "Cecile group." 



It is my opinion that tin might be discovered in this region, and it 

 might be recommended that efforts be concentrated on the streams head- 

 ing near or in the granulite dike which runs northeast from Dalumat. 



TRANSPORTATION. 



This is one of the worst features connected with mining operations 

 in this region. The roads which exist are in wretched condition; in 

 the Nagpartian district there is only one, which closely follows the coast. 

 To my knowledge there is not a single steel or stone bridge in the 

 province, and many of the Avooden ones are in a deplorable state of pres- 

 ervation. There are no bridges over the Laoag, the Bacarra, the Baruyen, 

 and Bamban Eivers, only bamboo rafts are available, and at certain seasons 

 of the year these can not be used. The transportation of supplies is 

 entirely dependent upon bull-carts and cargadores. The distance from 

 Pasuquin to ISTagpartian is only about one-fifth that from Pasuquin
