excepting perhaps those which are deep feeders, without liberal 

 supplies of manure, will suffer from starvation. As the same class of 

 soil extends southward through the Queen's Park in the direction of 

 the town of Port-of-Spain, the analysis of our soil will afford a 

 hint which should not be lost sight of by those having land under 

 cultivation. The following is the analysis : —

It is evident that with soil of the description obtaining at the 

 Eoyal Botanic Gardens, a large proportion of the material constituents 

 for plant growth must be furnished by the air, by the annual 

 Eainfall or by artificial means. It is therefore important for the 

 cultivator to know the amount and composition of the annual Rain- 

 fall and also of the chemical constituents of the atmosphere before 

 it can be accurately shewn what is really the best manure to 

 apply and the best methods of applying it. An example of an 

 effort in this direction is afforded in the report issued conjointly 

 by the Government Botanist and Government Analyst of Demerara 

 on experimental cane cultivation. The Rainfall for 1891 is shewn
