 and labor are available. Fresh bark should not cost more than 8 

 pesos per ton. On a basis of 50 per cent moisture and a 90 per cent 

 extraction, 4.3 tons of this bark will produce 1 ton of cutch, worth 140 

 to 150 pesos. It is believed that at present prices a net profit can be 

 made of 50 to 60 pesos per ton. As there is a large demand for the 

 product, its manufacture offers a promising field for investment. 



Further data and suggestions as to manufacture can be furnished to 

 prospective investors.
