22 ON THE OLDER FORMS OF 



So fill- as museum specimens and photographs have en- 

 abled me to judge, the roofing-tiles used everywhere in 

 India are of the normal type (usually imh.). Judging by 

 the form of the imbrex as shown in photographs of Bom- 

 bay houses, it would seem that in their manufacture a 

 tapering cylinder of clay is turned on a potter's-wheel, and 

 then cut in halves longitudinally, and these halves are used 

 as tegula and imbrex. As an evidence of this, in the Bora- 

 bay roof the tiles bordering the eaves terminate as cylin- 

 drical tiles, the tapering end entire and projecting slightly 

 beyond the eaves, while the larger end is cut half-way 

 through to acconnnodate the overlapping and inverted tiles 



that cover the under courses, as shown in fig. 33 (sketched 

 from a photograph in the India Museum, London). 



In Madras the normal tile {leg.) is used. In some cases 

 the eaves have two thicknesses of tegulte below and three 

 above (fig. 34). The tiles used at Poona, near Bombay, 

 are a variety of the normal type (fig. 35), the teguloe 

 being flat with upturned edges. 



This tile is 23 centimetres long ; the exposed edge is 

 14 centimetres wide and tapers rapidly to a width of 9 

 centimetres, with rounded ends. The imbrex is semi- 

 cylindrical, 28 centimetres long, 10 centimetres across at 

 the exposed end, and tapers to a width of 6 centimetres.
