Indian Forest Records. 
[VoL. I. 
It is proposed here to briefly enumerate, from reports subsequently 
received through the Eevenue Commissioner, Baluchistan, the steps 
taken by the Officers in charge of these forests to deal with the attack. 
During the autumn of 1905, 82 badly attacked trees were felled and 
burnt in New Shinghar and as many as 268 infected trees were counted 
in Old Shinghar. The latter could not be taken in hand during 1905 
owing to the want of funds and staff. In spite of the disparity in numbers 
of infested trees as shown by the countings made in the forest New Shin- 
ghar appears to have suffered more from the beetles than Old Shinghar. 
The large number of dead trees counted during the year in New Shinghar, 
982, probably accounted for the smaller number of green ones attacked, 
since the trees had become more scattered. 
Owing to difficulties in connexion with staff little work was undertaken 
during the year 1906, only 20 affected trees being cut out, making a total of 
92 affected trees cut out and burnt since the commencement of the cam- 
paign against the beetles. 
My examination of the infested trees in the Takht-i-Suleman area in 
November 1905 proved that the beetles pass through four generations in 
the year. From rough calculations made from measurements taken on 
the ground it was computed that an averaged sized tree in the Shinghar 
Forest could produce at a rough estimate a generation of 40,000 beetles. 
.Allowing for 50 per cent, casualties this would give rise by the end of the 
year to a progeny of 40,000,000 beetles on the supposition that the insect 
passed through four generations only during this period. 
From this calculation it follows that the removal of the 92 badly in- 
fested trees and the burning of the bark containing immature larvae, pupae 
and beetles may be safely estimated to have reduced the beetles that 
would have been present in the forest in the Spring of 1907 by some 
500.000,000, allowing for very heavy mortality amongst the over-winter- 
ing larvae and pupae. 
That the measures taken by the Political Agent, Colonel G. Chevenix- 
Trench, and the Extra Assistant Conservator of Forests, Bhai Sadhu Singh, 
were effective to a considerable degree in reducing very markedly the 
attack of these pests the following extract from a Note by Captain 
E. H. S. James, Pohtical Agent in Zhob, “ On the further ravages of the 
Borer Beetle of Shinghar for 1907 ”, will abundantly prove, although 
some of the conclusions arrived at by Captain James are perhaps suscep- 
tible of some modification. Captain James’ Report is as follows : — 
‘ ‘ Before proceeding to Shinghar, I was led to expect that I should find 
a forest of dead or dying Chilgoza (Pinus Gerardiana) trees due to the 
ravages of the Borer Beetle. On arrival I was agreeably surprised to 
find that the forest was by no means in such a bad state as was represented.
