YIELD AND DENSITY OF LATEX 89 



this amount, less 10 per cent, for loss in weight and 

 10 per cent, for expenses on fine, with no deduction on 

 scrap, or 210*58 pounds of fine and 46*9 pounds of 

 scrap. With the price in London at 33. per pound, 

 the equivalent rate on the Lower Purus is 2s. per 

 pound ; therefore the money value to the collector 

 is 21 is. for the fine rubber, and 3 2s. 6d. for 

 scrap, a total of 24 35. 6d. for seven months* work. 

 Against this sum take the cost of the absolute neces- 

 sities of life at the comparatively moderate prices 

 charged on this estate. The monthly requirements for 



each man are

Living in the most frugal manner possible on the 

 above scale, a collector will spend not less than 27 in 

 the tapping season of seven months, receiving 24 for 

 his work during that period. He remains with a debt 

 of 3, and no credit to help him to tide over the five 

 months of the year before he can resume his occupa- 

 tion. In the circumstances the situation for many 

 properties must be considered most precarious.
