Department of Agrlcultiire , "brings forth very strong arguments 

 for the belief that the good effect produced by planting trees 

 in coffee plantations is to Tae accounted for "by the fact that 

 nitrogen gathering trees, such as 'belong to the order Legumino- 

 sae, add fertility to the soil rather than "by the direct effect 

 of shade upon the coffee plant. The "building of pineapple 

 sheds is the greatest expense, and, aside from plants, the 

 cost of fertilizer the next roost Important consideration. If, 

 therefore, a shade can "be produced by the use of leguminous 

 trees, and they at the same time supply the amount of nitrogen 

 needed, it will greatly reduce the cost of producing the finer 

 varieties of pineapples. 



By-products 



The industry of raising the fruit for market is so 

 remunerative that no earnest attention is given "by the pine- 

 apple growers to the use of the "by-products. 



Some attention has "been paid to the preparation of extract 

 for flavoring and for medicinal pur'poses, but this was not for 

 the purpose of using up a waste product, but for the direct 

 profit of selling the extract. It is well knovrn that this 

 fruit contains an active principle called "ananas ine, " which 

 possesses active digestive properties. Advantage is taken of 

 this fact in the manufacture of pineapple digester and in 

 separating the active principle for medicinal purposes if 

 there should occur an over supply of pineapples.
