The following experiments have been made to determine the weight and transverse 

 strength : 



Skinner, No. 101, 1862 



Benson, Burma wood, bars 3' X 1'4" X I'l" 

 Brand is, No. 46, Burma List, 1862 .

 pieces and sapwood) ......

The wood is used for spear-shafts, scabbards, wheel-spokes, cattle-yokes, oil-presses 

 and rice-pounders ; it might be good for cabinet work. It has been tried for sleepers 

 both in Madras and in the Oudh and Rohilkhand Line, but has not succeeded. The 

 tree is pollarded for fodder, especially for elephants ; its bark is used for tanning ; it 

 gives a brown, clear, brittle gum used by the Nepalese as paper-sizing, by weavers in 

 cloth-printing, and in native medicine. With regard to this gum, Captain Campbell, 

 writing from Kumaun, says : " It sells at Rs. 2 per maund, and is used in mixing with 

 lime when white-washing ; it is also used for pasting, and is exported annually to the 

 amount of about 100 maunds from Garibolchand forest in the Kuinaon Bhabar."

10. SEMECARPUS, Linn. fil. 



Contains about 6 Indian species, mostly Burmese. Amongst them, besides the 

 species described, the most important are : S. travancorica, Beddome t. 232 ; Hook. 

 El. Ind. ii. 31. Vern. Natu shengote, Tarn. ; and S. aur iculata, Bedd., large handsome 

 trees of the Tinnevelly and Travancore hills.

 Gheru, Kari gheru, Kan. ; Bibwa, bibu, Mar. ; Chyai beng, Burm. 



A deciduous tree, bark J inch thick, dark brown, rough, exfoliating 

 in very irregular inner patches; inner bark fibrous. Wood greyish 

 brown, often with yellow streaks, soft, no annual rings. Pores scanty, 

 moderate-sized, frequently subdivided, well marked on a vertical sec- 

 tion. Medullary rays numerous, moderately broad, reddish ; prominent 

 on a radial section as long, narrow, dark-coloured plates. 



Sub-Himalayan tract from the Sutlej eastwards, ascending to 3,500 feet ; forests of 

 India, extending to Chittagong but not to Burma. 



Weight, 42 Ibs. per cubic foot (Brandis) ; 37 Ibs. (Wallich, Anacardium httifofium, 

 No. 4) ; 27 Ibs. (Kyd) ; the average of our specimens gave 37 Ibs. Kyd's experiments 

 with bars of Assam wood 2' X 1" X 1" gave P = 197. The wood contains an 

 acrid juice which causes swelling and irritation, and timber-cutters object to felling
