ton, while the Richmond increase with $65 manure per acre is only one 
ton. Ritchie's manure has done much better this time. The following is 
the analysis of Henrietta soil. Judging by the eye, this soil looks better 
" cured" than that of Richmond.

This is a very rich soil, all it wants is the application of Lime to 
decompose the large amount of sour vegetable matter it contains. 
General conclusions arrived at. 
(1.) That the ash and glucose are both increased in proportion to 
the amount of manure used, and that the increase is greater the more 
highly nitrogenous the manure is. 
(2). That the stronger a manure is, the less there is of fibre in the 
cane. 
(3). That canes appear to require chiefly Phosphoric Acid, Sulphu- 
ric Acid, and Nitrogen, that the best way to apply them is by 
Dissolved Guano mixed with Sulphate of Ammonia. 
(4). That it is difficult to give the preference to any of the manures 
of this nature used in these trials. I consider it is more satisfactory to 
import a good simple Dissolved Guano and mix it on the estate with 
Sulphate of Ammonia. 
(5). That Sulphate of Ammonia and Nitrate of Soda will stimulate 
canes when applied alone ; but their addition must always be accompa- 
nied with the burial of the " trash," when this is done I consider there 
is no fear of the Soil becoming exhausted by their use. 
(6). That I am of opinion that Nitrate of Soda is better for young 
canes than Sulphate of Ammonia, because its action is quicker. The 
canes are stronger at their birth, so to speak, and consequently are 
more able to stand droughts and heavy rains in their after life,
