In the Goalpara Division of Assam, 100 Sal trees, with a girth of 
5' 1" at breast-height, taken at random and measured for the purpose 
gave an average outturn per tree of 39 ‘67 cubic feet of merchantable 
timber roughly squared. Approximately the same result was also ob- 
tained in the Banjar Valley Reserve, Central Provinces, from the mea- 
surement of 6,954 Sal trees (sound and partly unsound), 6 feet in girth : 
6,954 trees, 6 feet in girth, yielding 256,630 cubic feet of merchantable 
timber. J

{Mr. R. Tiiompson, Divisional Forest Oflicer, Mandla, reports that from measure- 
ments taken in the Banjar Valley reserve, a 6. foot Sal tree will yield an average of .‘50 
narrow gauge or 10 broad gauge sleepers ; a Sal tree with a mean girth of 5 ' 3' yielding 
1.5 narrow gauge or 5 broad gauge sleepers. ^
