Rubber is the chief industry of the State, being its principal 
product and source of income. The predominance of this industry 
dates from 1863, and within a few years it superseded entirely 
the planting of rice, coffee, cocoa, sugar cane, beans and maize. 
Up to 1870 rubber was generally exported in the form of 
roughly made shoes, hats and caps, as well as in sacks and in 
bulk, the greater part of it going to New York, via Para. Later, 
the present system of biscuits or balls, cut and packed in cases, 
came into use. 
Considerable business has always been done in Amazon with 
the United States of America, although formerly the proportion 
shipped to America was greater than at present, as it was only 
in later years that the heavy competition by London and Liver- 
pool came into being.
