1 6 PERRY, Terraced Cultivation and Irrigation. 



Irrigation is found in Sumba, and among the Dusum 

 and coast people of Borneo. Also in central Celebes in, 46 

 the Sadang district and among the mountain group of 

 the Toradja. Terraced irrigation is also found among 

 the Bontoc, Infugao and Igorot of northern Luzon in the 

 Philippines. The cultivation is on an immense scale, the 

 terraces rising for thousands of feet up the sides of the 

 mountains. Terraced irrigation is also found in Formosa 

 and Japan. 47 



Miss Semple tells us that " the islands of Melanesia 

 show generally fenced fields, terrace farming on mountain 

 sides, irrigation canals, fertilised soils, well trimmed shade 

 trees, and beautiful flower gardens." 4? Irrigated taro gardens 

 are found in the Pelews and in Micronesia. 49 Irrigated 

 terraces are reported in New Britain, New Guinea, the 

 Solomons and the New Hebrides. 50 Dr. Haddon tells me 

 that irrigation in British New Guinea is confined to the 

 Massim District, but that drainage canals are made in 

 the Fly river district " and perhaps elsewhere in the 

 west." He says that " the irrigation in the east is for taro, 

 and very elaborate irrigation works have been made a 

 long time ago which are still kept up." Near Wamira, 

 Bartle Bay, is an aqueduct about 60 feet long over a gully 

 30 feet deep, " a very fine piece of work." (Newton. In 

 far New Guinea, pp. 123-4.) 



Terraced cultivation is found in the d'entrecasteaux 

 islands, and in Aurora.' 1 Mr. A. M. Hocart tells me that 

 " terraced irrigation (for taro always) occurs on a large
