Col. Burney [Journ. Asiat. Soc. of Bengal, Yol. I., p. 170) has 

 published some interesting remarks on its use. A tar is 

 extracted from the wood, which is used as an application to tlie 

 sores of draught cattle to prevent maggots breeding. As a rule 

 white ants will not touch teak wood, and the use of teakwood 

 tar has been suggested as a remedy against these destructive 

 pests. The wood is also not easily affected when exposed to 

 damp weather, and baskets for holding orchids are commonly 

 made of teak in Burmah ; while orchids are also preferably 

 mounted on teak blocks. 



At a meeting of the Nilgiri Natural History Society in 1 887, 

 Mr. Lawson showed a specimen of a whitish mineral substance 

 found in a teak tree growing in the Government Plantation at 

 Nilambur. This peculiar secretion is not altogether unknown 

 to officers in the Forest Department, and its composition has on 

 more than one occasion been investigated by chemists. 



In 1870 the fact of calcareous masses occurring in timber 

 was brought to the notice of the Asiatic Society of Bengal by 

 Mr. R. V. Stoney, who stated {ride P. A. S. B., May 1870, 

 p. 135) that many trees in Orissa had pieces of limestone or cal- 

 careous tufa in their fissures, but principally Asan [TerminaUa 

 tomenfosa, W. and A.), Sw^vm {Zizyphus rugosa, Lam.), Sissu 

 {Dalbergta Sissii, Eoxb.), and Abnus (Diospuros mclanoxylon, 



Koxb.). * ^^
