It is estimated that about 2,50,000 viss of thitsi were exported 
during the years 1912-15 to Burma. East of Taunggyi the price is 
about Rs. 85 per 100 viss. In the Myelat and in the Lawksawk State, the 
price varies from Rs. 65 to Rs. 75 for red thitsi, and from Rs. 90 to 
Rs. 100 for black thitsi. 
XXI. In the Yaw division Rs. 957 only has been received during 
the last ten years as revenue on thitsi ; the trees are few and scattered 
and the trade is of little importance. 
XXII. Minbu. —The trade in these forests has never been of any 
great extent, but villagers have tapped the trees regularly for their own 
uses. Licenses are issued and the product is usually collected at Palan- 
gyin, Leinzu, Magyizu and Singaung in the Minbu district and Kyagan 
in the Magwe district, where a number of small traders live. Since 1906 
10,000 viss have been extracted in the Minbu district, for which Govern¬ 
ment received Rs. 1,329 as revenue; and during the same period 4,900 
viss have been obtained in the Magwe district, Rs. 490 being realised. 
Inside Reserved forests, the license fee is Rs. 20 per hundred viss, and in 
unreserved forests, it is half as much. 
General. 
Thitsi, when it comes on the market, is graded into 3 classes accord¬ 
ing to its drying capacity : these classes are known sometimes by the 
terms (i) Pure black thitsi, (ii) Mixed black thitsi and (Hi) Red thitsi. 
Pure black thitsi is the best available on the market, and should be 
the pure unadulterated product; the mixed black thitsi is said to be 
adulterated with the ash of rice husks, etc., and with a concoction made 
from the bark of Albizzia stipulata in order to improve the colour ; red 
thitsi is said to be still further adulterated, and to have derived its red 
colour from rain-water coming in contact with it at the time of collection. 
The three grades of material were analysed by Professor Dunstan at 
the Imperial Institute, London in 1914 with the following results :—
