for hardness and durability; the white ant will not touch 
it; it shrinks in seasoning one-eighth inch per foot of 
sui face, and the density is 5 lbs. 10 oz. per foot super¬ 
ficial. It is one of seven or eight species of trees which 
Dr. Falconer, in his report of the Teak forests of Tenas- 
serim, earnestly requests the Indian Government to pre¬ 
serve.” 
Five specimen logs of the Pyengadu, each about 
20 feet in length, and 20 to 24 inches square, were sent 
to Woolwich Dockyard in 1863, for trial experimentally 
in ship-building; but, as they were found to have exten¬ 
sive heart-shake, they were scarcely fit for constructive 
purposes. If, therefore, the heart-shake defect seen in 
these logs fairly indicates the character of this wood, its 
value as building timber would be seriously affected. I 
am, however, of opinion that this is not the case, and 
that these were probably some chance pieces which 
happened to be in the way when specimen logs were 
required. Three of the logs here referred to were kept 
for several years at Woolwich without any good oppor¬ 
tunity offering for their employment, and after this lapse 
of time they did not appear to have undergone any 
change, or to be in the slightest degree deteriorated. 
The specific gravity of these logs was about 1176, 
while that given by Dr. Hooker is 1080 ; the difference 
is therefore not very important. 
I found in the Commissariat Stores at Moulmein, 
besides the Teak and Pyengadu, many other valuable 
woods of building sizes, and the following are especially 
worthy of notice, namely, the Padouk (Pterocarpus) of 
a deep ice! coloui , the I arewah, and the Penthityah, both 
of a dark reddish-brown colour; the Kammone ; the 
Annan ( FcigrcBu cius), and the Kamonpew, each
