THE GEAR A RUBBER TREE. 
Nahiku, Maui, May 4, 1911. 
Editor Forester and Agriculturist: — I beg to enclose herewith 
an extract from a very interesting article on the Ceara rubber 
tree, which has been found to be the tree best suited to our local 
conditions, for cultivation. 
The prejudice against this tree for plantation purposes is being 
gradually removed, and it occurs to me that this article may prove 
of interest to your readers, both as indicating the position of a 
recognized authority, and as tending to show that the Ceara tree 
appears to have found the Hawaiian climate peculiarly favorable 
for latex production. 
Very truly yours, 
W. A. Anderson. 
Extract from Paper by JVilliaiii Wichcrlcy, E. R. H. S., in the 
Rubber World for Dec. /p/o, on the Ceara Rubber Tree 
( M anihot Glaziovii) . 
"The Manihot Glaziovii, which produces the Ceara rubber of 
commerce, enjoys a much wider sovereignty as plantation rubber 
then does the Hevea or Para rubber tree, and it is therefore 
astonishing to find existing throughout the whole of the Mid-East 
a grounded prejudice against this valuable and exceedingly profit- 
able tree. ... 
"After making careful inquiries in other districts, I found that 
the real cause why these trees had been condemned was that the 
planter, after having got his tree to maturity, did not know what 
to do with it ; and there appeared to be nobody who could assist 
him in the matter. The areas of Ceara rubber that would be 
]:>riceless now as producing lands had been sacrificed to this want 
of knowledge. 
"From my own observation I should say that the tree, which 
was introduced into Ceylon by the botanist Cross, was from seed 
obtained in the Rio de Janeiro district, with the result that most 
of the Ceara in Ceylon is of a hybrid character, and therefore the 
true Manihot is only met with in a few isolated districts. It is, 
nevertheless, a very good tree, and, if properly handled, will 
always be more profitable to the planter than any other kind of 
rubber he can grozv, provided that the district and the rainfall 
are suitable." 
The paper goes on to describe proper conditions and methods 
of cultivation and continues : 
"There should not be the slightest diflficulty associated with the
