us or not, in the annual cutting of each species, culms of all ages must be 
dealt with mixed and as a whole or not at all. The effect of the Econo¬ 
mist’s report upon my department of the enquiry has therefore been to 
largely limit its scope, and to direct it into those channels which his care¬ 
ful and systematic investigation into the economic conditions governing 
the exploitation and growth of bamboo shows to be the most practical. 
3. My investigation has therefore been restricted to the five species, 
viz., Bambusa arundinacea, B. Tulda, B. polymorpha, Cephalostachyum 
pergracile and Melocanna bambusoides, found by the Economist to be the 
ones most worthy of serious attention in the districts he has reported 
upon, and the chief points to be investigated as ascertained from a 
careful study of former efforts and results, qualified and limited by the 
Economist’s conclusions, are :— 
{a) The suitability of the five species mentioned for the manufacture 
of cellulose at a marketable cost. 
(b) Whether the fact that culms of all ages must be dealt with mixed 
and as a whole constitutes a serious difficulty. 
(c) Whether the nodes must be cut out and rejected. 
(d) Whether the differences between species will permit of their being 
mixed during treatment. 
It will be convenient to divide the report into sections as follows :— 
A. —Physical. 
B. —Analytical. 
C. —Digestions. 
D. —Microscopical. 
E. —General conclusions. 
4. The following definitions and abbreviations will be made use of :— 
N.A.D., or normal air dry=containing 90 per cent, of absolutely dry 
substance and 10 per cent, of water. 
NaOH —Sodium hydroxide in its commercial form as Caustic Soda of 
76 per cent, strength. 
Na^S =: Sodium Sulphide . 
B. P. = Bleaching powder {calcium hypochlorite) containing 35 per 
cent, available chlorine.
