section shows numerous fine concentric lines, with pores in short pale wavy 1 

 bands arranged concentrically. 



Durability. -The wood is not usually proof against white-ants, but has 

 been found to last as long as 9 years in the ground without deterioration . 



Weight.- The wood is fairly heavy, the mean of recorded figures being 

 55 Ibs. From the Darjeeling terai a weight of 67 Ibs. has been recorded 

 (Gamble). 



Strength. The value of P, which represents the strength of a bar of 

 timber calculated from the length between supports, breadth, and thickness 

 of the bar, and the weight in pounds which when placed on the middle of 

 the bar causes it to break, has been calculated at 835. This is a high 

 figure as Sal gives 790, Teak 600 and Shisham 796 (Gamble). 



'Fissibility. The wood is very difficult to split being placed by Mr. 

 R. 8. Troup at the foot of a list of 61 Indian woods tested by him, its index 

 figure being 44-78, Teak giving 1-75, Toon 4'25, and Sal 9-33. 



Calorific power. If available in quantity for fuel it would be good, as 

 its calorific power is high, the number of British Thermal Units recorded 

 by Mr. Puran Singh being 8,368, Shisham giving 8,312, Teak 8,560 and 

 Sal 8,88 ! . 



Seasoning. In the Central Provinces the trees of this species, with 

 others, are usually felled during the rains and the stems left unbarked 

 leaning against others for a month or two. A paste of cowdung is also 

 used at times and the timber is sometimes immersed in water, but it can 

 be seasoned very well by being kept in the shade for a few months after 

 felling, as it is not liable to split badly. 



Uses. It is in great demand for ploughs, shafts of carts and of wheels, 

 handles of tools, bed-legs, yokes, spindles and other purposes requiring 

 strength and toughness. The supply is not equal to the demand for these 

 purposes and much more could be disposed of than is at present available. 

 It has been tried at Naini Tal for casks for beer and was found to be very 

 suitable. A small consignment was sold in London in 1878 for 3 per 

 ton. 



4. Minor Products. 



When blazed the tree yields an astringent red gum and a decoction of 

 the bark is used in Chota Nagpur when the urine is too dark coloured 

 (II. H. Haines) . The bark is pounded and used to intoxicate fish and the 

 twigs are lopped for cattle fodder. In the Yeotmal Division of Berar lac 

 is grown on the trees, which are soon killed by it. The fibre is
