Dr. Dafert remarks :— 
1, In case it is desirable to replace one or the other of these materials 
by some equivalent substance, the tables of composition in Part 1. 
should be referred to. 
2. Where stable-manure, compost, &c., are not available, an increased 
artificial fertilisation must be resorted to. Hither the application 
of the easily soluble mixtures must be doubled, or they may be used 
in combination with more slowly available mixtures; in the latter 
case, Thomas’ slag especially should be taken into consideration. 
3. When the condition of the soil is abnormal, the above formule must 
be altered. For instance, it is wasteful to apply plaster to 
calcareous soils ; soils rich in potash require a much smaller quantity 
of this ingredient than that recommended above. If the soil is 
deficient in phosphoric acid, the percentage of this ingredient in 
the mixtures must be increased. 
4, The age limits given in the table should be changed to suit varying 
conditions, the figures being mean values and intended for average 
trees. 
SUCCESS OF PROPER COFFEE FERTILISATION 
Though the number of reliable observations regarding the effect of the 
applications recommended above is not large, the examples given below will 
convey an approximate idea of what can be accomplished by means of a rational 
cultivation of the coffee-plant. 
{nm 1893 the Agricultural Institute of the State of Sio Paulo assumed the 
management of an almost abandoned sixteen-year-old plantation, the returns 
from which scarcely covered the cost of harvesting. This field was of special 
interest to the institute, as many million coffee-trees in Brazil are in a similar, 
if not poorer, condition. The plantation was first carefully cleared, and its 
yield determined. The yield from 5,512 trees in 1893-94 was— 
1,426:57 gallons coffee = 1,786°8 lb. bean-coffee, 
or per tree L104 quarts ,, = OR3 ,, 2 
Immediately after harvesting, the poorer trees were fertilised with half 
of the quantities given in the table, and the soil thoroughly cultivated. At 
the end of three months, the soil had improved considerably, the blossoms 
were especially numerous on the fertilised trees, and the development of frnit 
was normal. 
These 5,512 trees yielded in 1894-95— 
7,483°36 gallons coffee = 9,911°9 lb. bean-coffee, 
or per tree ASE) aE 5, S= IAS, 1 
In 1893-94: the average value of the yield from each tree was 25 pf. ‘The 
expenses amounted to somewhat over 43’pf., and the loss was therefore 18 pf. 
Tn 1894-95 the value of the yield from each tree was 134 pf., while the 
total expenses did not amount to more than 44: pf.-—i.e., every tree produced a 
profit of 90 pf. The fertiliser applied to each tree was worth 16 pf. 
This is only the beginning, and, judging from the present favourable 
condition of the plantation, the next yield will be at least double that of the 
previous year. 
Dr. James Warne, of Itapira, Brazil, inaugurated a more intensive 
system upon his farm ten years ago, and procured— 
82,672°5 lb., or about 7-7 ib. of bean-coffee 
per tree, from 15,000 partly (two-thirds) very old trees, by means of fertilisation 
with stable-manure. 
During the last few years, artificial fertilisers have been largely used, 
although not to the exclusion of other manures; the mixtures were similar to 
those used in Campinas, but the percentage of nitrogen was higher. he
