EXPLANATION OF THE PLATES. 



PlatG in. a. Arcnga saccharifcra Labill. (Bagot.) Upper part of a tree, showing 

 the enormous fruiting inflorescences (halto), and, lower down, on 

 the left, the severed peduncle (hotohon i\i haunt) of a male inflores- 

 cence (mcang) from which is suspended a bamboo container (tagock) 

 for the juice (nira). The collector {maragot) is in the tree at the 

 right of the inflorescence which is being tapped. 



Plate III. b. Interior of a sugar grove, showing the rough trunks of the bagot, 

 clothed with the sheaths of dead fronds and with the black fiber 

 known as idjock. 



Plate IV. a. Base of a bagot showing the ladder {sige), made by lashing notched 

 poles together with rattan. 



Plate IV. b. The hive-shaped clay furnace (delihan) over which the juice is boiled 

 down in a large iron pan {halanga). 



Plate V. a. Smoking bamboo containers over a small furnace similar to that used 

 for boiling down the juice. The large tagock is inverted, and into 

 it is passed a smaller bamboo which conducts the smoke from the 

 furnace. Yeasts and other microorganisms are destroyed in this way 

 after each use of the container. The tngoek on the right shows 

 the rope, woven from idjock fiber, by which the tagock is sus- 

 pended from the mcnng. 



Plate V. b. The process of smoking containers over small, individual, conical fur- 

 naces made out of sheet iron. 



Plate VI. a. Pouring the melted sugar from the balanga into the mold (tocangan) . 

 The mold is first wet with water, so that the truncated cones of 

 sugar (kotocl) will come out readily. 



Plate VI. b. Packages of sugar ready for market. Each package (tirocsan) con- 

 sists of two kotocl wrapped in banana leaf. 



All of the plates are from photographs taken by the writer in Asahaii. Figures Ilia 

 to Va show scones at a sugar camp on the path from Kampong Ajer Tolock to Ladang 

 Si Djaboet. The photographs for figures Vb and Vib were made at Silo Maradja, and 

 that for plate Via at Mariadoge.
