solid masonry gate, and the heading is cut for some distance 

 through a rock cliff. There are 10 canals in Bangui-Nagpartian, 

 each 1 kilometer or more in length. The two longest are about 

 3 kilometers long. 



The people of Pasuquin, south of Nagpartian, have "exploited 

 the available water supply to a considerable extent. In the 

 northern part of the territory of this municipality, 4 small 

 rivers are made to irrigate about 1,000 hectares of rice land 

 during the wet season, and in the southern part of the town 

 about half as much land is watered from a lateral of the Paratong 

 canal, which draws water from the Bacarra or Bubuisan River. 

 An attempt is made to water these 500 hectares the year 

 around, but complaints made by the landowners indicate that 

 the supply of water is unreliable owing to certain imperfections 

 in the canal. 



Laoag, the capital of the province, is badly off with regard 

 to irrigation. Certain works which formerly utilized the water 

 of one or two minor creeks for wet-season irrigation have been 

 destroyed in course of time, and according to the latest data 

 available only about 600 hectares of land in the municipality 

 are under irrigation. Of this land, about 100 hectares are 

 irrigated only during the wet season. The rest is watered by 

 a branch of the Kamungao canal, which draws water from 

 the Bacarra River. The people of Laoag who use this canal 

 complain of a shortage of supply during dry weather. This 

 shortage, in the opinion of an engineer of the Bureau of Public 

 Works, is due not to a failure of the supply in the river, but to 

 defects of an engineering order. 



Laoag is situated on the largest river in the province. There 

 is a gauge record of a quarter of a million second liters for 

 this stream, and it is probable that this amount of water is ex- 

 ceeded at times. The want of irrigation work on this river is 

 sufficiently accounted for by the size and the difficulty of the 

 problem of utilization. The problem is further complicated by 

 the circumstance that the river bears a heavy raft-traffic in 

 rice which is floated from towns on the upper reaches to Laoag, 

 and any obstructions to this traffic would cause an uproar from 

 those interested in it. 



San Miguel has 9 ditches which irrigate some 500 hectares 

 during the wet season. 



Piddig is better supplied with irrigation than any town in 

 the province except the three dependent on the Bacarra River. 

 Nearly 2,000 hectares of land in the municipality are under 

 irrigation, more than half of it all the year around. The water
