less than 25 ft. apart each way, and planted in 

 ordinary orchard form, but 30 ft. by 30 ft., or 

 forty- eight palms to the acre, is generally found 

 to be best, and some even advocate 40 ft. apart. 

 Mr. Herbert S. Walker, of the Chemical 

 Laboratory, Manila, also writing in the Philip- 

 pine Journal of Science^ on the nuts from San

On a hectare (nearly 2\ acres) at seventy 

 trees to the acre, 175 trees should be growing 

 from which, at forty nuts per tree, a total of 

 about 7,000 nuts may be expected. For San 

 Ramon this is considered a high average, 

 but for the sake of comparison it will serve 

 the purpose. On the basis, therefore, of the 

 analyses given above, the nuts would annually

 per hectare, from the soil ; and to this must
