controlled by Laboratory analyses and observations. A small 50 gal- 

 lons still with telescopic head and detachable retorts will be constructed 

 to deal with the various types of distillation at present existing in the 

 island. A sufficient quantity of rum will thus be obtained to enable 

 it to be tested commercially and chemically. Careful data as to atten- 

 uation and yields will be recorded and tables for use in Jamaica Distil- 

 leries will be (irawn up and made available. 



Nursery for Cane Varieties — bome six acres of laid at the Hope 

 Experiment Station have been established in the cultivation of cane 

 varieties. This is to be exclusively a nursery and distributing medium, 

 the merits of the canes will be worked out on the estates by the varie- 

 tal test^. At Hope, seedling canes will be raised from selected and 

 cross fertilized seed, the best can s from Barbados and Demerara will 

 be grown for distribution To ensure the cane cultivation it is pro- 

 posed to set aside the new reservoir exclusively for the_ irrigation of 

 the canes. All canes will be distributed from Hope gratis. 



^'/wca^ton.— Special courses for the study of sugar and rum have 

 been arranged. Ten book keep rs each year will be offered £10 each 

 to cover the expense of attending at the Laboratory in Kingston. 

 The.-^e courses will be held o t of crop 



Management.— T\ie Board of Agriculture is the Q-overnment autho- 

 rity in cjntfol of this scbeme and of the finance^ but it is considered 

 desirable to have a special comm ttee of maiigement consisting of 

 representatives of the Su^^ar Industry, to supervise the working of the 

 Scheme and to ensure that the experiment.s are properly^ directed to 

 meet the practical needs of the industry as a whole. It is proposed 

 that this Committee sbould report to the Board of Agriculture from 

 time to time as to the progress of the work and shall be responsible 

 for the proper conduct of the Scheme as authorised by the Governor 

 in Privy Council 



The Island Chemist is to be the executive officer in charge of all 

 the operations of this scheme and will ac;. as Secretary of the Com-
