from the air. Carbohydrates form especially good mediimis for their development, and it 

 has been found that the activities of these organisms are increased by an increased amount of 

 this substance. 



While e.xcellent results have been attained by the use of low-grade molasses for fertilizer 

 in other countries yet it remains for the planters here to determine results under Philipjjine 

 conditions, and the best method of handling their material. In some places where irrigation 

 water is applied, the molasses is mixed with the water and applied in the usual manner. 



The plant-food material contained in molasses will vary somewhat with the methods of 

 its production, clarifying agents previously used, etc. 



The following table will indicate the composition of ash from different molasses:

In order to make a wise selection of the method of handling the different liy-products the 

 manufacturer must take into consideration many factors. Among them will l)e the quantity of 

 his output, the facilities for handling it in any specified manner, the demand for different 

 finished products to be made therefrom, etc. .All of these and many other points must receive 

 due consideration by a manager who expects to attain success in his work. — -Philippine A^ricuZ

VUELTA ABAJO 



Senor de la Cruz, Inspector General of 

 Agriculture, is quoted as stating that after a 

 visit to Vuelta Abajo, he thought that the 

 Cuban farmers in that district paid entirely 

 too much attention to the growing of tobacco. 

 Double the quantity of tobacco that is neces- 

 sary is planted every season with consequent 

 low prices to the grower. He does not think 

 it feasible to erect any large sugar centrals 

 in the district, but seems to think that the 

 farmers should pay more attention to crops 

 other than sugar or tobacco.
