ALCOHOL FROM COCO-NUT PALMS 539 



Exhaustive study by Bureau of Science in the 

 Philippines Dr. H. D. Gibbs, a prominent inves- 

 tigator copra and oil exports from the Philip- 

 pinesextraction of sap tuba or toddy v. arrack 

 how the sap is obtained Dampier describes the 

 process in 1686 the Madras method the Javanese 

 method yields obtained two analyses of the sap 

 100 gals, toddy equal 25 gals, arrack sugar 

 from the sap - coco-nut, nipa and other palms 

 the supply of nipa palms inexhaustible nipa 

 sugar less costly than cane sugar trees yield 

 fifty years and more yield per hectare making 

 alcohol instead of sugar the question of yields 

 palm vinegar Gibbs reports it to be excellent 

 vinegar from coco-nut milk O. W. Barrett on 

 the Philippine coco-nut industry 75 per cent, of 

 their copra lost why this is so evils of close- 

 planting Barrett discusses palm sugar, toddy, 

 &c. varieties of nuts the old green and yellow 

 comprise, perhaps, 98 per cent, of the whole. 



PAPER-MAKING FROM COCO-NUT HUSKS ... ,.. 558 

 Philippines alone probably produce 250,000 to 300,000 

 tons of husks a year can rough paper from coco- 

 nut husks help relieve the demand for wood-pulp 

 paper? the matter discussed. 



THE MECHANICAL EXTRACTION OF COCO-NUT FIBRE 561 

 Coir prospects in the Philippines coir v. copra

 combings mattress fibre the willowing machine 

 the baling press hand-spinning recommended 

 coir fibre for insulating cables its advantages over 

 jute The Fibre Machinery Go's plant for treating 

 10,000 husks per day.
