-and sub-heads of enquiry are as follows :— 
1. — Burma. 
Based on the reports received from the Chief Conservator of Forests,

timber into planks and scantlings after being girdled for 
3 years and then felled, in order to compare it with the 
converted material prepared according to the methods 
described below. 
<h) To fell six other trees of each of the above species, in order 
to (i) (e ) prepare logs from the same 6 ft. long, and 
season two of each according to (i) (b), (i) ( c ), (i) (d) and 
(i) ( e ); after these logs are seasoned, they will be convert¬ 
ed into planks to be compared with those to be converted 
green as described in the next para. 
(Hi) (a) To convert green logs into planks of the above twelve 
species and also of (13) Xylia dolabriformis and (14) 
Fagrcea fragrans which will be (1) stacked in the shade in 
open piles and weighted above. (2) First immersed in 
water for six weeks after conversion and then stacked in 
open piles in the shade. 
(iv) To prepare 10 M. G. sleepers of (1) Dipterocarpus alatus, (2) 
Dipterocarpus tuberculatus, (3) Xylia dolabriformis, (4) 
Schleichera trijuga, (5) Lager stroemia Flos-Regince, (6) 
Pentacme sauvis from—

(d) Logs treated with cowdung and tar mixed and then sea¬ 
soned. 
(e) Seasoned logs and fix iron “ S 55 shaped clamps to each 
end of the sleeper after preparation. Such an experi¬
