The Nos. in fig. 3 refer to those given to the soils in Table VI. 

 Chemical and mechanical analyses of soils from Mountain 

 Province are given in Tables VI and VII. 



CAGAYAN 



The soils of the Cagayan Valley are generally considered to 

 be exceedingly fertile, and are used for the cultivation of corn, 

 tobacco, etc. Much of the district is inundated from time to 

 time, and the composition of the soils is continually changing. 

 The general characteristics may be indicated by the chemical 

 and mechanical analyses given in Tables VIII and IX. 



LAGUNA AND TAYABAS 



Laguna and Tayabas Provinces have been found especially 

 suited to the production of coconuts, and the soil samples, the 

 analyses of which are given in Tables X and XI, have been 

 taken in an effort to give information with regard to some of 

 the controlling factors of the ideal soil for this crop. 



PAMPANGA, BATAAN, TARLAC, AND BULACAN
