CEARA OR MANICOBA RUBBER.* 



INSTRUCTIONS FOR ITS CULTURE AND EXTRACTION OF RUBBER. 



Owing to its easy acclimatisation and small requirements with 

 respect to soil, Manicoba will become a product of great im- 

 portance, coming next to that of coffee, to-day so depreciated in 

 its market value. 



It requires however constant care and work. 



Certain plants do not constitute what might be looked upon as 

 capital, they ripen in a few months and then disappear, others 

 like coffee, cocoa, and the Manicoba represent a real income 

 owing to their being long lived. 



It is therefore on account of its great interest that we endea- 

 vour to make known some particulars of this most useful plant. 

 Showing how its plantation should be made, how it should be 

 treated, and the manner of extracting the Rubber. This is what 

 we intend to do, making use of other works already issued, in- 



nding to add to them without damaging their clearness. 



THE TREE. 



The Manicoba (Manihot Glaziovii) belongs to the family of 

 of Euphorbiaceae to which also belong Hevea brasiliensis which 

 prodnces the excellent rubber of the Amazon. 



It grows not only in the interior, but also near the sea, and on 

 mountain sides doing well in the pastures ranging betwoen 15° 

 C. and 32 C.[59° F. and QO° F.] that is all over Brazil.
