ol6 Report on the Exhibition and Trial of Implements 
Eobey's cultivator, manufactured by J. and F. Ho-\vard, consists of a 3-fur- 
row plough, driven by a stationary engine, with windlass, &c., and works on 
the triangular system. The plough consists of a strong iron frame, with three 
sets of coulters, mould-boards, &c., arranged on one end, and three on the 
other contrariwise, the one being raised and the other lowered by means of a 
joint at the middle of the frame. This implement was not sufficiently sub- 
stantial for the hard ground. It was also with difficulty kept in the work 
with two or three men riding on it. The quantity of work done was at the 
rate of 45 perches per hour, requiring 9-horse power. The time required for 
changing position was 25 minutes. 
The steam cultivator exhibited by J. and F. Howard, and invented by Smith 
of Woolstone, is too well known to need any description here as to its working 
arrangements ; but during the years it has been in use it perhaps was never 
more severely tested than at Warwick. This system requires two operations : 
the first with a cultivator having three strong wrought-iron shares, taking a 
breadth of 26 inches, and the second with one of larger dimensions, fitted with 
five shares, taking a breadth of 48 inches, and worked at the same depth as 
the other, but in a transverse direction, thereby removing the whole of the soil 
to a given depth, and leaving the surface in a rough state, well suited for 
autumnal cultivation. The draught of this implement was irregialar, and we 
noticed a jerking, caused probably by the very hard state of the land. The 
quantity of work done by this cultivator was at the rate of 114 jierches ^\ 
hour, for only one operation, requiring llf-horse power. The time required 
for changing position was 30 minutes. 
Lastly, we come to Fowler's well-known system of steam cultivation ; and 
we may here mention that considerable improvements have been carried out 
since last year in simplifying the various parts of the apparatus, by which the 
loss of pow er from friction has been diminished, and consequentlj' a consider- 
able saving in the wear and tear effected ; and another feature is the simple and 
very easy mode of changing the plough into' a cultivator, bj" putting on pecu- 
liarly constructed shares and mould-boards, thereby retaining all the steady 
cutting properties of the plough, while the cultivator breaks up the land in 
beautiful style, and leaves it in a thoroughly rough and irrcgidar state for the 
action of the atmosphere. The work done by the 4-furrow plough or cultivator 
was at the rate of 105 perches per hour, requiring llJ-horse power. The time- 
required to change jiosition was 57 minutes. 
The Cotgreave plough was also tried with the same apparatus, and made 
very good work. 
Fowler's 3-furrow plough or cultivator is worked by an engine of less power 
but on the same principle as the 4-furrow plough : this is a very good imple- 
ment, making a complete fallow of the hardest land at one operation. The 
quantity of work done was at the rate of 100 perches per hour, requiring 
T^-horse power. 
The comparative trials of the four last-mentioned cultivators will stand 
thus : —
