contents are of a propagandist nature and of popular character, mak- 

 ing irrigation projects, water-power development, and domestic water 

 supply appear dependent on forest conditions. The few isolated ex- 

 amples of torrential action cited suggest the propriety for the Forest 

 Service of enlarging in this field of inquiry and collecting with dis- 

 cretion all the cases which can be truly authenticated of changed water 

 conditions due to deforestation and reforestation.

A Further Note on the Antiseptic Treatment of Timber. By R. S. 

 Pearson. The Indian Forest Records, Vol. VI, Pt. IV, Pp. 128. 



The book gives in great detail the results of treatments of several 

 species of Indian timber by brush and tank treatments with a variety 

 of preservatives. Most of the preservatives were patented prepara- 

 tions or materials sold under patented names, but coal-tar creosote, 

 zinc chloride, and sodium fluoride were also used. Although the ex- 

 periments are not complete, practically all the treatments have ma- 

 terially increased the life of the wood. Creosote oils are giving better 

 service than soluble salts. 



Pressure-creosoted ties are being used to some extent in India, al- 

 though they have to be imported. The author points out that there is 

 a shortage of naturally durable timber in India which is cheap enough 

 for ties, and that considerable quantities of ties are being imported 

 from Australia and the United States. These conditions could be very 

 largely corrected by the use, after preservative treatment, of some of 

 the less durable Indian woods. 



While the book is in much greater detail than will appeal to the 

 average reader and is not summarized as well as could be desired, it 

 gives an idea of the status of the use of treated wood in India.

"Overwhelming" is the first thought which comes to the reviewer 

 who contemplates the task of wading through the two volumes which 

 record the work of the Swedish Forest Experiment Station for the 

 years 1916-17, comprising not less than 1,300 pages. "Magnificent" is 

 the first impression on opening the book, for it is made up in first-class 

 style, on paper such as we are not accustomed to, as a rule, in our
