Part II.] Pearson - : Antiseptic Treatment of Timber. 
The Chief Engineer, Madras and South Mahratta Railway, in his letter 
No. E-485-a-1925—9643 of the 28th April 1910, to the address of the 
Forest Economist, states that “ some timber pieces were treated with 
Solignum which is a preparation for preserving wood from the ravages of 
white-ants and tried in a small white-ant hill itself. None of the pieces 
have been touched by white-ants, It was very satisfactory.” 
Twelve species of timber treated with a hot solution and applied with 
a brush, were laid down on the 6th September 1909 ; their condition up to 
the date of inspection was as follows :—
