case  of  Castilloa  that  the  period  of  transition  or  change  in  the 
quality  of  the  rubber  yielded  by  the  trees,  namely,  from  a gummv 
substance  to  true  rubber,  coincides  with,  or  closely  follows,  the 
period  when  the  species  first  begins  to  produce  ripe  seeds. 
The  rubber  recently  obtained  possesses  a fair  amount  of  resi- 
liency with  very  little  gumminess.  It  is  anticipated  that  the 
trees  will  yield  rubber  of  good  quality  in  the  course  of  the  ensuing 
year.
