must then have an assistant for carrying and smoking. The 
yearly production of a seringueiro amounts, in the better rubber 
forest properties, to upwards of 1,000 kilos of dry rubber. 
Some owners offer a reward, such as for instance, a gold 
watch, for the most industrious and luckiest seringueiro. On 
the Seringal S. Francisco, for the crop year 1911-1912, a serin- 
gueiro won the gold watch who had collected 2,500 kilos. The 
annual highest yield of caoutchouc from the Castilloa was only 
1,700 kilos, for the forest there in regard to Castilloa is already 
very much exhausted. Otherwise the yields of this rubber are 
more variable and higher than those of fine rubber. 
If the price of rubber rules high, a seringueiro has quite a 
considerable income and with a little frugality can acquire a 
property. 
If, on the other hand, the price of rubber drops below five 
milreis, the seringueiro has trouble to make both ends meet 
with his income and easily gets into debt. The supplies that he 
must purchase from the proprietor or his representative (lessee) 
are very expensive. The customs duties, the long haul and 
consequently high freight, the risk, the different losses, which 
the proprietor suffers through debtor workmen, and the occasional 
high price of fine rubber, which forces all prices upward, makes 
everything in upper Acre very dear.
