are laid close to each other, and across these laths of split 

 bamboo about an inch wide are fastened down with filaments 

 of rattan-cane. The sides of the houses are closed in with 

 the bamboo opened and rendered flat by splitting or notching 

 the circular joints on the outside, clipping away the corres- 

 ponding divisions within and laying in the sun to dry pressed 

 down with weights. Whole bamboos often form the upright 

 timbers, and the house is generally roofed in with a thatch 

 of narrow split bamboos six feet long, placed in regular 

 layers, each reaching within two feet of the extremity of 

 that beneath it, by which a treble covering is formed.

Another and most ingenious roof is also formed, by cutting 

 large straight bamboos of sufficient length to reach from 

 the ridge to the eaves, then splitting them exactly in two, 

 knocking out the partitions and arranging them in close 

 order, with the hollow or inner sides uppermost; after 

 which a second layer with the outer or convex sides up, is 

 placed upon the other in such a manner that each of the convex 

 falls into the two contiguous concave pieces, covering their 

 edges, the latter serving as gutters to carry off the rain that 

 falls upon the upper or convex layer."
