THE PHYSIOLOGY AND DISEASES 

 OF HEVEA BRASILIENSIS. 



By T. Petch, b.sc, b.a., 

 Mycologist to the Government of Ceylon. 

 London, Dulau & Co., 1911. 



That Mr. Petch's book on the botany 

 and diseases of the great plantation 

 rubber tree of the East would constitute 

 a valuable contribution to the subject 

 was a statement which we should 

 scarcely have hesitated to make before 

 even turning over its pages ; that it 

 should be the best book on the general 

 physiology and pathology of rubber yet 

 published was also no more than we had 

 a natural right to expect. We have no 

 hesitation in saying that our expect- 

 ations are fully justified by the ably 

 written volume before us. Having said 

 so much we have still less hesitation in 

 subjecting it to a careful scrutiuy with 

 the object of bringing to the author's 

 attention any defects we may be able to 

 discover. For from defects of some kind 

 the best written book can never be 

 wholly free. 



The book is remarkable tor the absence 

 of any preface or introduction, so that 

 the author's object in writing it is now- 

 where explicitly stated. We may there- 

 fore be wrong in supposing that he has 

 desired to cater at the same time for the 

 wants of the scientific expert and those 

 of the planter. If this supposition is 

 correct, however, it is scarcely a matter 

 for surprise that the scientific botanist 

 should find in it a good deal that is 

 already familiar, or that the planter 

 should find it necessary, as we antici- 

 pate, to apply a good deal of concentra- 

 tion to its persual. 



Seventy-nine pages only out of 263 

 deal with actual fungus diseases. The 

 remainder of the book is devoted to the 

 structure and physiology of Hevea — 

 particularly of its laticiferous system. 

 Tapping experiments and the effect of 

 different tapping systems are discussed 

 at considerable length. Other chapters 

 deal with the merits and defects of pre- 

 pared plantation rubber, with general 

 questions of sanitation and with various 

 abnormalities. There is also a chapter 

 on the " Art of Experiment" which is, 

 we think, unique in a book of this kind.
