6S8 Report on the Exhibition of Implements 
in breadth, and being cleverly worked by four horses. It is en- 
tirely composed of wrought iron, with an excellent lever appa- 
ratus for adjusting depth and raising the tines out of the ground. 
This implement worked in a very lively manner, and was thought 
to offer less drag to the team than any of the others ; but it fell 
short of the Uley in surface-skimming. 
A scarifier by Messrs. Barrett and Ashton, of Hull, was also 
commended by the judges, who, however, conclude their observa- 
tions on this class of implements by remarking that they consider 
them yet open to great objections, and that they need consider- 
able imj)rovement. 
The silver medal was awarded to Messrs. H. Smith and Co. 
for their implement. 
Harroics.- — The judges report most * favourably of a new ex- 
panding harrow invented by Mr. Richard Coleman, of Col- 
chester. This implement is mounted on four light wheels, ad- 
justable by levers to govern the depth of penetration by the teeth 
into the soil, so that it becomes a light or heavy harrow at will. 
It is readily expanded to cover 12 feet, or contracted to the com- 
pass of 4 feet. It worked admirably on very rough land ; and 
the Society's prize of bl. was conferred on Mr. Coleman for this 
meritorious invention. 
The Norwegian harrow, which created so much interest at the 
Shrewsbury meeting, and a description of which will be found in 
that Report, was again produced by Mr. Siratton, of Bristol, with 
several improvements in its construction and means of manage- 
ment. The judges considered the specimen covering 5 feet in 
breadth to be the best adapted for all descriptions of soil ; and 
observed that it is capable of thoroughly breaking up the furrow 
slices from 3 to 6 inches deep, as the farmer may require, leaving 
the soil in a beautifully pulverized condition. An award of 5/. 
was given to Mr. Stratton for this implement; and a silver metlal 
to Messrs. Barrett and Ashton, of Hull, for a spiked roller or 
harrow — a powerful tool, which was thought well adapted lor re- 
ducing very hard cloddy land, but not calculated t(j leave it in 
such fine tilth as the Norwegian. 
Drills. — The competition for the three prizes offered by the 
Society was ably sustained by the several well-known skilful 
manufacturers of these machines. Mr. Hornsby, ol Grantham, 
obtained the prize for the drill for general pur])oses ; Mr. Hunter, 
of Ulceby, Lincolnshire, that for turnips on the flat; and INIr. 
Teasdale, of Burneston, near Bedale, Yorkshire, that for turnips 
on the ridge. 
The remark by the judges that these invaluable implements 
may now be considered to rank among the most perfect in the 
list of agricultural machinery will be appreciated by the members
