THE ALCOHOL INDUSTRY. PART L

Hagonoy contained 2,700 trees per hectare, while a clean unbroken rectangular 

 area of 2,000 square meters showed a little over 2,800 plants per hectare. Eough 

 counts in various places on small plots confirmed the estimate for clean land 

 areas of about 2,500 to 2,700 plants per hectare. Water courses, ponds, and foul 

 patches will reduce the average for the whole region to about 2,250 or possibly 

 2,000. 



The yield of sap from each plant. — Four plants originally investigated 

 in the early stages of this work, yielded during a 17.5 hours' flow a 

 highest number of 890 cubic centimeters and a lowest of 240 cubic 

 centimeters, the average for the four plants was 606 cubic centimeters. 

 This observation, in view of later data, seems to be too high. 



Six average plants on the San Esteban estate were tapped by skilled 

 natives at 6 o'clock in the morning of November 21, 1910, and the sap 

 flow measured each twenty-iouT hours during the entire sap flow. The 

 duration of the shortest flow was fifty-three days, while that of the longest 

 was seventy-five days. 



The data are recorded in Table T. 



Table V. — The sap flow, in cubic centimeters, from six nipa palms during the 

 entire period of one season's production.
