(bj The extension of the system of plot control 
adopted in the manurial experiments to trials of selected 
varieties of seedlings. This is considered desirable to 
enable it to be ascertained with certainty the characters 
of the various seedling varieties. An area of 6 acres 
will for the next few years suffice for this purpose. 
(c) The extension of the present experiments with nitro- 
genous manures to a few selected seedling varieties. This 
is of some importance, as probably the various varieties 
may show different requirements, — with regard to the 
amounts of manurial nitrogen, owing to the different 
lengths of time required by them to arrive at maturity. 
An area of 3 acres should suffice for this. 
[d) The extension of the area at present occupied in 
raising selected seedlings for supplying canes to the 
planters for experiments on a large scale. It is desir- 
able to set free for use for other purposes the land at 
present under cultivation with this object in the nursery 
at the Botanic Gardens. The adoption of suggestions 
(a) and (bJ will to a certain extent effect this, but an 
area of 4 acres used solely for the purpose of raising 
seedlings for the June planting season will be desirable. 
fej The removal of all experiments with seedling 
canes from the present field to land nearer the Govern- 
ment Botanist's house. This will set free a sufficient 
area of land upon whicli the duplicate series of manu- 
rial experiments can be conducted and facilitate the 
exercise of the constant supervision necessary to enable 
a correct judgment to be arrived at with regard to the 
merits of a seedling cane during its first year of exis- 
tence. An area of say 4 acres may be requisite for 
this purpose. 
(/) The growth of small areas of different varieties 
of canes selected for the purpose of raising seed for 
propagation ; two acres will be necessary for this purpose. 
(g) Experimental examinations of theories adduced 
with regard to the influence of saccharine strength of 
the canes from which the tops have been taken for 
planting upon that of their offspring. An area of about 
2 acres will suffice for the examination of those theories 
and of others from time to time put forth upon the cor-
