are applied in greater quantities than the more expensive soluble 
fertilizers. Is this not largely due to the present ignorance re- 
garding time, quantity and location, coupled, possibly, with the 
difficulties hitherto met with in administering the dose at the 
roper moment and in the correct place? For a man to attempt

to a depletion of organic matter, it is equally possible that ways 
and means will be discovered not only for maintaining it at its 
present level but also for increasing it in the ordinary course ot 
cultivation.
