weight of the driver. This implement does excellent work in 
eradicating weeds and cultivating the soil thoroughly. 
Tue Disc CuLrivators. 
have now become quite a favourite. They are made of different 
sizes. For orchard and vineyard work the one horse dise eultiva- 
tors have two gangs of four dises each and the two horse dises two 
gangs of five dises each. They have a forecarriage, carried on 
wheels, which is operated by means of a lever from the riding seat 
and can thus turn on narrow headlands in a smaller circle than 
the shaft or pole cultivators. They are very suitable for chopping 
up and turning in long weeds and trefoil and also cover crops of 
field peas in the spring time. They cut through and pulverise 
heavy clods of clay which would hardly be touched by other im- 
plements and are particularly suitable for clay soil which clogs 
the mouldboard of share ploughs or fail to be pulverised by 
others. A very good two horse dise cultivator is manufactured by 
the State Implement Works at Rocky Bay and sold for £15 each. 
The dises are British made and the framework made in Western 
Australia. The cost at present is £15 but will very likely come 
down when discs and steel become cheaper. 
Tue Acme Harrow. 
is also a very good implement (cost, two-horse £6) for reducing 
the surface of the field to a fine tilth. 
It is also a riding harrow, and consists of sets of two curved 
blades or coulters made of spring steel, one of which performs a 
paring action, and the other one.a crushing action, the implement 
performing the three operations of clod-crushing, levelling, and 
harrowing at one time. It is of light draught, simple and durable; 
unlike the spading harrow, it does not turn under the soil like a 
plough. In very mellow soil, and in covering in seed in such soil, 
the driver should not ride.
