This beetle not only eats the shoot or growing point but com- 

 pletely tunnels out the tree hollowing it to the base. This we have 

 never seen here. R. ferrugtneus never attacks the base of the 

 tree as this insect is said to do, nor is there any fear of its entering 

 the trunk by wounds made by the tree-climbers. It invades the 

 holes made by Oryctes rhinoceros but it more often attacks the shoot 

 without requiring any assistance from wounds, of any kind. 



Another Rhynchophorus is figured and desci 

 tree which seems more to resemble R.ferrugin 



Two other species of weevil are also described, which apparently 

 chiefly attack trees already damaged by the other larger species. 



'Rubber Cultivation as an Investment." 



illh 



and publis 



Agency in London, gives an account of cultivation and preparation 

 and uses of rubber, as well as calculations as to profits and valua- 

 tion of estates and an useful section on How to read a Rubber 

 cultivation Prospectus. The pamphlet is one which any one can 

 read with profit short as it is. It is of course chiefly for investors 

 and is certainly well suited for their needs. It contains a number 

 of pictures showing cultivation methods, tools, etc., but some ot tfte 

 latter are fast going out of date. Spiral tapping, and the short 

 taps are pretty well things of the past and perhaps few now use 

 the Bowman and Northway knives, and pricker. However, this is 

 of little importance as the book is a guide rather to investment 

 than cultivation. The figures as to cost and profit are very 

 moderate and give a very fair idea of what a planter or investo 

 stands *-
