1. STATE OF MATTO-GROSSO 
The capital, Cuyaba, and the principal port, Curumba, belong 
to the hydrographical system of the Paraguay River. 
The boundaries of this State, formed by the Amazon River, 
embrace the upper basin of the Madeira River, which as the result 
of an agreement with the State of Amazonas appertains to Matto- 
Grosso, whereas it previously belonged to the former State. 
This territory constitutes the judicial and administrative prov- 
ince of Santo Antonio do Madeira. 
The executive and fiscal administration is entrusted to a Fis- 
cal Delegate in Manaos. The collection of duties is attended to 
by the State Customs of Amazonas. 
The rubber producing rivers, with total production of Matto- 
Grosso, are:

deira & Mamore.... 153,000 150,000 143,000 202,000 
During the first half of the current year the production has 
shown a considerable increase, this being largely due to the open- 
ing and developing of the Madeira Mamore Railway, which passes 
through the whole region of these rivers.
