as quill bark called by the natives canuto ; that from the 

 solid trunk is called tabla or planclia. It is sewn up in 

 coarse canvas, with an outer covering of fresh hide, forming 

 packages called serons. Thus prepared, it is transported to 

 the coast for shipment. 



From the careless way in which the bark-collectors have 

 hewn down the trees, often digging up the roots themselves, 

 the production has greatly decreased. When the root is 

 allowed to remain, and the stem hewn as near as possible to

 in the space of six years again produces bark. In the colder 

 regions twenty years are required before a tree is fit to be 

 cut down.

 years before been carried by the Dutch to Java, where, how- 

 ever, from want of sufficient care at first, its cultivation has 

 not been so successful as it appears to be in India.

 his mouth, which he chews, and replenishes from time to time. 

 Thus the coca leaf is a great source of comfort and enjoyment. 

 As he journeys, his ch-uspa or coca-bag, made of llama cloth,
