» Data for 8 months only available. 



These data led to the belief that the daily and annual production 

 obtained by the distillers from the trees was much below that which 

 could be secured by proper management. A test of 100 trees over a 

 period of one month was planned in order to demonstrate the results 

 which could be achieved by the employment and efficient supervision of 

 sufficient and competent labor to gather the tuba and keep the trees in 

 good condition to produce the greatest flow of sap. A distiller in the 

 Province of Tayabas cooperated with us, and 100 average trees in a 

 grove in which his distillery was located, were properly marked so that 

 they could be distinguished readily, and sufficiently experienced tuba 

 gatherers were detailed to collect the tuba and perform the daily routine 

 of cutting the stems. The supervision of these laborers and the details 

 of the test were conducted by Mr. Thomas Hoey, agent of the Bureau of 

 Internal Eevenue in the district, to whom the credit for the successful 

 prosecution of the investigation, and my thanks for assistance to me 

 while carrying on the work in the Province of Tayabas, are due. 



The tuba was gathered twice during the day, in the morning and 

 evening, and the flowing flower stems were cut twice daily at the time 

 the tuba was coUected.^^ 



"Mr. Hoey states: "Two men did the work, one in the morning and one in 

 the afternoon. The walks are so arranged that the mangitero starts in at the 

 first tree of the walk and travels from tree to tree on bamboo bridges, taking 

 the tuba until he comes to the last tree of the walk. This work was under the 

 close supervision of the Government ganger stationed at the distillery and tlie 

 tuba was measured by him. 



Slices were cut from the flower stem twice a day, at the time of gathering 

 the tuba in the moi'ning and evening. It has been found that, while an increased 

 daily yield may be obtained by cutting the flower stem oftener, the stem will 

 be entirely cut away before the flow is at an end. A test by me showed that a 

 tree produced 1.5 liters for two slicings and 2.0 liters for three slieings in twenty- 

 four hours."
