mark to invent a method for obtaining a pure culture of each yeast- 

 plant, and so enable brewers and others to grow the particular yeast 

 desired in order to obtain a special product. 



Prof. Hansen is still continuing his researches at Carlsberg, near Co- 

 penhagen, and a former pupil of his, Mr. A. Jorgensen, is the Director 

 of a Laboratory in the same place where students from all parts of the 

 world come to learn the technical methods of investigation of yeasts. 



There is nothing certainly known as yet about the fermentation of 

 Rum, — the morphology of the yeast-plants or other microbes that 

 cause the fermentation, the cause of the general superiority of Ja- 

 maica Rum, and the reasons for different qualities of that spirit on 

 neighbouring estates. 



The investigation is likely to prove intricate from the necessity of 

 cultivating separately each kind of microbe to be found during the fer- 

 mentative process ; and the difficulty is enhanced by the possibility that 

 forms that appear exactly similar under the highest powers of the 

 microscope may prove to differ widely in their life-history and the pro- 

 ducts to which they give rise. It may take years to thoroughly work 

 out the problem, but it is an interesting one both from the scientific 

 point of view, and also from the practical bearing it may have on the 

 manufacture of rum. 



Mr. P. H. Greg, from Jamaica, studied under Prof. Jorgensen for 

 some months, and is continuing his studies here. My object was to 

 gain an insight into the subject, so that I might be able to give advice 

 or help to any planters or students working at it in the island. 



Whenever opportunities occurred, I took note of Institutions for the 

 advancement of Agricultural Science, or for education and training in 

 Agriculture. 



Although Denmark is a comparatively small and poor country, large 

 sums of money are devoted to the furtherance of agriculture. There is 

 an excellent Agricultural College in the capital, Copenhagen.. The 

 veterinary branch includes three large buildings with stalls for horses 

 suffering from various diseases on which a veterinary surgeon demon- 

 strates to the students. There are large Gardens and Grounds : a Bo- 

 tanic Garden for the illustration of lectures in Systematic Botany with 

 a special area for economic plants ; an Arboretum for the culture of 

 forest trees ; a Fruit Garden where various Apple and Pear Trees are 

 grown trained as espaliers in different ways, and where varieties of 

 strawberries, etc., are cultivated. The influence of various manures is 

 illustrated by a collection of plants growing in large flower pots. There 

 are large and well-equipped laboratories for the study of the physi- 

 ology of plants and of chemistry. Amongst the collections of plants 

 there is a fine seri s illustrating the diseases of plants consisting of dried 

 specimens of woods attacked by fungi, and of plants in the herbarium, 

 and of others preserved in alcohol. There is a large staff of Professors 

 who lecture on the theory and practice of agriculture. 



In Copenhagen itself, and at other places on the Continent, there are 

 Institutions founded and supported in many cases by the liberality and 

 enthusiasm of private individuals ; they are known as Experimental 

 Stations and are designed for the scientific study of some particular 

 branch of Agricultural Science. A good example of such an Institution 

 exists at Copenhagen, founded by Mr. Fjord., for the study of milk and
