It must be clearly understood that the above figures represent only 
a very rough, estimate of the number of trees available for tapping, and 
also that the species occurs in many other localities, though most 
commonly in those mentioned. 
2. Method of Tapping. 
(i) Nimar Experiments. 
A good deal of difficulty has been experienced in ascertaining the 
best method of tapping Boswellia , which has necessitated a series of 
experiments being carried out, not only in widely separated areas but 
at different times of the year, as the season of‘tapping has a marked 
effect on the yield. Moreover, as little was known about the tapping 
of this tree when the enquiry was first taken in hand, a number of diff¬ 
erent methods were tried, most of which gave poor results. Pre¬ 
liminary experiments were undertaken in the Siwalik Division, United 
Provinces, and in the Melghat Division, Central Provinces, the results of 
which were sufficiently encouraging to justify more detailed experiments 
being carried out in the Nimar Division, Central Provinces. It was, 
therefore, decided to send the Assistant Forest Economist, Mr. E. 
Benskin, to Nimar, for this purpose. The results of his experiments 
are summarized as follows :— 
* NOTE— The Conservator of Forests, Berar Circie, in forwarding the reports from the D. F. 
expresses the opinion that the estimates are high and should be treated with caution.
