Calthrop measured a tree 20 ft. in girth at 6 ft. from the ground, with a clear 

 bole of 60 ft. to the first branch. Two trees measured by me in 1906 in the 

 Mohnyin forest, Katha, had the following dimensions : 



(1) Girth at breast-height 10 ft. 3 in., height 152 ft., bole 93 ft., estimated to contain 282 cub. ft. 



of timber. 



(2) Girth at breast-height 11 ft. 4 in., height 135 ft., bole 93 ft., estimated to contain 320 cub. ft. 



of timber. 



These two trees are show^n in Figs. 263 and 264. 



Mr. C. G. Rogers ^ records the cubic contents of five trees recently felled 

 and logged in the Mehaw reserve, Pyinmana, as follows : 



These trees grew on rich well-drained soil at the foot of the hills east of 

 the Sittang river. Mr. Rogers also records in the Gamon reserve of the Zigon 

 forest division, a tree with a height of 153 ft. and a breast-height girth of 

 15 ft. 10 in. 



Among large logs recorded from Burma is one mentioned by Dr. J. 

 Nisbet.- It was cut in the Shweli forests, Ruby Mines district, by Messrs. 

 Darwood & Co., and launched in one of the floating streams about 1898 ; it 

 was quite sound, had a length of 82| ft., a butt girth between 12 and 13 ft., 

 a top girth between 7 and 8 ft., and a mean girth of 10 ft., and contained 

 516 cub. ft. of timber. Another sound log recorded by Mr. S. Carr ^ in the 

 Yamethin district had a length of 64 ft. and a mean girth of 13 ft. 9 in., giving 

 a volume of 756 cub. ft. 



General distribution. Teak is indigenous throughout the greater part 

 of Burma and the Indian Peninsula, in Siam, and in Java and other islands 

 of the Indian Archipelago. In Burma the northern limit of teak lies about 

 25 30' N. lat., that is, some distance outside the tropics, while its southern 

 limit is in the Amherst district between 15 and 16 N. lat. ,Qi\ the east it 

 extends beyond the frontiers of the province, wdiile on the west it does not 

 extend beyond the western watershed of the Irrawaddy and Chindwin rivers. 

 In the Indian Peninsula the northern limit of teak is in the western Aravallis 

 'in Rajputana at 24 42' N. lat., thence eastward through Central India to the 

 Jhansi district at 25 33', entering the Banda district, thence in a south- 

 easterly direction to the Mahanadi river. From this northern limit it extends^ 

 southward to Tinnevelly and Travancore. In Burma and the Indian Peninsula 

 it is by no means continuous within the limits mentioned, but is confined to 

 tracts of greater or less extent separated by other tracts where it is absent or 

 of very local occurrence. 



Although the teak reaches large dimensions in some of the forests of 

 western and southern India, Burma is the great source of supply of large-
