Ground nuts (Arachis hypogaeaj aic cuUivated to a limited extent 

 throughout the West Indies,'{or eating. They are however practi- 

 cally ignoied as a source of oil ior cooking purposes or oi oil cake. In 

 view of the extensive importations nf oil, oil nieal and oil cake into these 

 colonies it would appear that more attention should be given to the culti- 

 vation oi ground nuts, not necessarily in the first place for export, but 

 to supply local demands. 



The paper comprlses 1 The ascertained facts relative to the cuiti- 

 vation of ground nuts in the West In dies. 2. The uses made at pre- 

 sent oi the crop in the colonies and also, ior comparison, their uses in 

 other parts of the world. 3. Suggestions ior utilizing ground nuts to 

 replace some oi the expensive imported oil meals etc. 4. A discussion 

 oi the value of ground nuts as an article of export, with notes on the 

 result of an experiment in bleaching them to improve their market value.

The report gives a summary oi the work carried on during the year, 

 consisting mainly oi experiments with economic plants. Several new 

 plants v/ere introduced during the year including British Honduras 

 Mahogany, and select varieties oi Cotton and Colombian Cassavas. 



The results obtained irom the experiment plots demonstrate the 

 suitabllity of local conditions Ior the cultivation of onions, cotton, ginger, 

 pineapples etc. Nearly 20 00U plants, exclusive oi seeds and cuttings, 

 Vv-ere riistributed to planters during the year. W. G, Freeman.

An account, ior the use oi the practical agriculturalist, of the manner 

 in v/hich iixcd Nitrogen is lost and gained in the soil. The root tubercle 

 bacteria are described and fully figured in the plates. The matter oi the 

 artificiai inoculation of the soil is taken up and an improved method 

 recently experimented with, for accomplishing this is described. The 

 usual trouble with the cultures distributed, has been that the media on 

 which they were grown contained so much nitrogen that the organisms 

 seemed to lose their power of fixing the free nitrogen. By gradually 

 decreasing the amount of nitrogen in the culture medium it has been 

 found possible to even incrcase their natura! activity in fixing free ni- 

 trogen. A consideration of the best manner of distribution and of methods 

 oi use of the cultures, closes the article. H. M. Richards (New-York).
