Plot No. 4. On this plot are growing twenty-five trees 

 of Cola acuminata, a tree of West Africa, one of the species 

 which yield the Kola nuts of commerce. These nuts are 

 said to be used in Tropical Africa in the same manner as betel 

 nuts in Asia. They are chiefly valued in Africa for satisfying 

 the craving of hunger, and for enabling those who eat them 

 to endure prolonged labour without fatigue. There is a 

 large internal trade in the nuts in that country. 



Plot No. 5. Here may be seen twenty trees of the Para 

 rubber, (Hevea brasiliensis) , native to the forests of the valley 

 of the Amazon, and now extensively cultivated in the Middle 

 East. This species yields the best rubber. The enormous 

 demand which exists for rubber, and the many uses to which 

 it is put are well known. 



Plot No. 6. This is devoted to Spineless lime plants, a 

 variety of the common Spiny lime, (Citrus medica, var. acida). 

 The common lime was introduced into the West Indies by the 

 Spaniards. It is now extensively cultivated in Dominica. 

 The fruit when ripe falls to the ground, and is then collected 

 and placed in heaps for conveyance to the mill for crushing. 

 The juice is exported raw for making cordials, and, when 

 concentrated about 10 : 1, in order to reduce bulk, for making 

 citric acid. This process of concentration unless carefully 

 carried out is very wasteful, and, in order to overcome this 

 preventable loss, the manufacture of calcium citrate, which 

 represents a great advance over concentrated juice, was 

 commenced in 1906. Recently a factory has been erected by 

 the well-known firm of L. Rose <x Co., Ltd. for the local 

 production of the finished product, citric acid. Otto of limes 

 is prepared from the rind of the fruit by the ecuelling process, 

 and essential oil of limes by distillation of the juice before it is 

 concentrated or used in the manufacture of citrate of lime. 

 There is also a considerable trade in shipping green limes to 

 New York, Canada, and Great Britain, and a small business in 

 pickling limes in salt-water for export to Boston, U.S.A. 

 The value of the lime products exported from Dominica during 

 1919 amounted to /196.401. 



Plots Nos. 7 and 8. Both of these are manurial experiment 

 plots of cacao (Theobroma Cacao).
