Drill for distributing Superphosphate. 
of a mile from the tank or river ; and in the same proportion 
with the larger drills. 
The merits of this implement will be more clearly explained 
by stating that dissolved bones (superphosphate of lime), or any 
soluble manure, are more evenly distributed in liquid than in 
compost; inasmuch as the difficulty of mixing properly the super- 
phosphate in a sufficiently friable state for drilling is entirely 
superseded by the revolution of the cups keeping the liquid in a 
constant state of motion from the bottom of the drill, thereby 
giving to each plant an equal share of the manure. 
It is an admitted fact that vegetables cannot take up as food 
anything solid ; therefore the advantage of liquid manure must 
be apparent to every one. 
The various enemies to which the turnip is subject in its 
earlier stages are, by this system, in a great measure defeated, 
the manure being so regularly deposited in the drills, that im.me- 
diately the seed germinates it finds its food so congenial to its 
growth that it is soon placed in safety. 
The drill is very simple in its construction, and may be made 
to any size. Of the two sizes that have been found most con- 
venient, that for one horse is 4^ feet wide, which is best adapted 
for the ridge system, depositing two rows at 27 inches (this has 
been highly approved of for drilling mangolds) ; it can also be 
worked on the flat at the same distance, or three rows at 18 
inches. The other is 6 feet wide, the coulters of which may be 
varied to five rows at 14 inches, four at 18, four at 20, three at 
24, or seven rows for corn at 9 inches, with liquid manure, or ten 
rows of corn without manure, and for spreading liquid broadcast. 
The liquid-manure box can be removed, and the drill worked 
as a common corn- drill, when manure is not required.
