168 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 



Work notes for each month of the year, Lists of trees for various 

 soils and situations, Prices of contract work, Tables of weights 

 and measures, etc., etc. This latter portion of the book occupies 

 thirty-five pages. 



For the assistant forester or young student, jottings, in tabu- 

 lated form, of occurrences in connection with his daily work 

 should prove interesting and useful for future reference, and for 

 the keeping of such records Webster's Diary seems well suited. 

 The recommendations in the monthly work notes are sound, so 

 far as they admit of general application. 



The book is neatly got up, bound in liui[» leather, and can be 

 carried in the pocket without inconvenience. Its price is not 

 prohibitive, and the Diary should receive a welcome from 

 foresters and their assistants. J. F. A.

This is a short manual treating of the many uses to which saw- 

 dust and some other forms of wood waste are now being applied. 

 A number of furnaces, specially constructed for the combustion of 

 sawdust as a fuel, are noticed and illustrated on a small scale. 

 The manufacture of oxalic acid Is treated of at some length, and a 

 short description of recently-introduced processes is given. The 

 production of artificial wood, and its employment for decorative 

 purposes, according to various methods, forms an interesting 

 chapter. The manufacture of blasting powder from sawdust 

 receives some notice, but the great industry of wood-pulp manufac- 

 ture for the making of paper and the like is dismissed in a few 

 sentences. A considerable number of minor uses to which sawdust 

 is put receive a {jassing reference.
