INTRODUCTION. 
THIS Note on the Antiseptic Treatment of Timbers has been pre¬ 
pared with a view of briefly reviewing all past experiments made in this 
connection in India, especially with reference to sleeper timbers ; to re¬ 
cord the results of the experiments made at the Imperial Forest Research 
Institute during the last two years with a variety of antiseptic solutions ; 
and to lay down the lines on which it is proposed to conduct further 
enquiry on this subject. 
Chapter I deals with the present position of affairs in India, with spe¬ 
cial reference to the antiseptic treatment of sleeper woods, a brief sum¬ 
mary of the possible methods of treatment, and timbers suitable for 
sleepers. Chapter II discusses the various processes of injection by 
pneumatic and hydrostatic agencies. Chapter III deals with the Open 
Tank and Brush Methods of treating timber, and Chapter IV is a short 
resume of the work which it is proposed to carry out in the future. 
Where reports or other documents have been quoted in the body of 
the Note, the names of the authors, where possible, have been given. 
The writer's best thanks are due for advice and help given by Professor
