machine did excellent work. 
Messrs Hartjen showed an apparatus tor 
charging’ several sprayers simultaneously 
with both fluid and air by what they term 
their battery system, which should be useful 
where several machines are in use. 
Vnother machine working on the pneu¬ 
matic principle was the Alpha, exhibited by 
Messrs. Robinson Bros., Lim., Ryders Green, 
West Bromwich. This machine has no in¬ 
terior working parts, it being simply a cylin¬ 
der of lead-coated steel, which, after being 
o-tbirds filled with liquid, is charged by 
I ordinary bicycle tyre pump, eighty to 
a hundred strokes sufficing to fully charge 
the machine. The Alpha is fitted with capital 
nozzles that produce an extremely fine, mist- 
like spray. The great advantage of a pneu¬ 
matic machine is that the operator has both 
hands free for . directing the spray, since 
there is no continuous pumping to do. 
A new and improved pattern of the well- 
known Four Oaks machine was shown by the 
Four Oaks Spraying Machine Company, Sut¬ 
ton Coldfield. The usual copper tank is fitted 
with a detachable inner lining of tin, making 
the machine acid proof. Air chamber and

instead of at the side. It is at the best jj x.- i fyninihr -rmf 
a fatiguing task to pump continuously with pump, and an additional strainer p t

a Conner m'acHnr‘'lined'and covered with open tank on the carriage, so that once 
■ and an agitator has been fixed to the charged with air, the pressure ^u *>e re- 
n ntlflitional strainer put into tamed ns long as desired. Tlie tank is of 
course, kept well filled by buckets, and a 
semi-rotary pump forces the liquid into the 
cylinder, an agitator attached to the pump 
keeping the mixture in proper suspension. 
The carriage stands on four broad-faced iron 
wheels, and is fitted with pony shafts. It is 
a machine capable of getting through a 
great amount of work, two 6ft. corrugated 
brass lances and two 2()ft. lengths of stout 
rubber hose giving reach enough for hops 
or tall trees. Another big tank machine 
that aroused considerable interest was the 
Enots Utility, shown by Messrs. Benton and 
Stone, Bracebridge Street, Birmingham. A 
strong pump is fixed in the centre of the 
tank, with a strainer at its b^. M ith 
each descent of the pump handle a cir¬ 
cular brush passes over the strainer so 
that sediment or powder is removed, keep¬ 
ing the gauze clean and in free working 
^^Bot’h jets of the long lances are under 
control of a handle on the tank, so that 
the man at the pump can turn either or both 
spravs off or on at will. An ingenious at- 
taqhment to the nozzle automatically re¬ 
moves any obstruction from the jet by simply 
turning off the spray. The pump \yorks very 
easily, and the only criticism of this machine 
we have to offer is that a more effective 
agitator is required to keep such mixtures as 
lime-sulphur or Paris green in suspension. 
The Four Oaks Battle machine is very use¬ 
ful, suitable for either garden, nursery, 
or fruit plantation. It consists of a strong 
oaken tub of narrow oval shape, slung on 
wheels after the style of a water Harrow 
The widest measurement, from the hub of 
the wheels, is 23 inches, so that it is of handy 
size for narrow rows or pathways. A double 
action pump forces the fluid up a central 
column branching at the top into two out¬ 
lets. Armoured hose and long lances car^y
