Query 1 — Crushing Clods. 
Query 2— Strong Lands. 
John DRABWEr.i,, 
Thm-crul't Hall, by 
Ui)thevhara. 
I purchased my clod-crusher of you iu the 
spring of 1842, and have made several opera- 
tions with it, the results of which I have now 
much pleasure ine{)mmunicatingto you. Alter 
a heavy crop of turnips on strong limestone 
land, which was eaten off by sheep during the 
wet weather, it \\as plouglu'd up for barley. 
The soil tore up in cakes and clods as hard as 
bricks. I know no implement which would 
ha\e enabled me toreducethis land to a proper 
tilth, to sow barley, but your clod-crusher. 
Its cost of 20 guineas was ab\uidantly repaid 
by the crop. I have Ibund it equally service- 
able in preparing ray stronger lands for tur- 
nips last season ; and have this year 17 acres 
of strong hazel land upon a strong clay sub- 
soil, which is now drained every 4i lands, 
burying 60 full loads ot stone per acre, besides 
tiles, &o. The whole was done in March and 
April ; and we have now growing upon this 
land 13 acres of tuinips, and 4 of rape, as pro- 
mising as any in the neighbourhood. The soil 
has always been considered much too strong 
for turnips, and without the clod-crusher any 
atlempt to prepare it tliis season would have 
been quite out of the question. 
I have used your patent clod- 
crusher, for wheat, upon land 
consisting of limestone, gritstone, 
and strong laud, sown partly in 
autumn and partly in the spring." 
I have in each instance left a 
portion unrolled ; and those parts 
show the evil arising from the 
grub, wireworm, and Might, in 
different situations, tothe amount 
of 6 to 18 bushels to the acre. 
T. C. Johnson, 
Clievit Gran^'c, by 
Wakefield. 
I am perfectly satisfied that it is a goed im- 
plement, and has been of great benefit in 
breaking up my hard turnip-land. 
Right Hon. Lord Hawke, 
Womersley Park, 
Pontel'ract. 
I have tried your patent clod -crushing roller 
which I purchased of you last spring, and it 
fully answers my expectation. 
Sir J. V.B. Johnstone Bt.. 
HackneaS, 
near Scarborough. 
My agent informs roe that he has found it 
most useful in the preparation of land for 
sow ing turnips : without it, indeed, it would 
have been very difficult to obtain a sufficiently 
fine surface for the reception of the seed. One 
of the principal tenants also used it, with 
great success, for the same purpose. 
J. Beaumont, 
Brantingham. 
I think it most invaluable. 
Excellent for this purpose. 
William Stickney, 
Ridgmount, Holderness. 
8th mo., 2, 1843. 
A most excellent implement for bre.iking up 
clods upon our strong land fallow, and thereby 
liberating the seeds of weeds, which then come 
in contact witli finer and moi^ter mould, by 
which means they vegetate, and after-opera- 
tions destroy them. Also, it frequently liap- 
])ens that a considerable cpiantity of the roots 
of couch-grass are enveloped in the large 
clods, which our harrows and the common 
roller will not break ; tlie clod-crusher will 
scratch them out, and expose them to the sun 
and atmosphere, by which means they wither 
and die. 
Sometimes most excellent. I 
mention one circumstance in 
particular: — A neiglibour of 
mine had sown a large field with 
oats, very dry and cloddy. The 
harrows had but little effect ia 
covering the seed, but were borne 
up Ijy the cliids. which were only 
rolled from one place to ano- 
ther, the land being very dry 
on the surface. Both my neigh- 
bour and I thought there was 
little prospector a crop. I lent 
him my clod-crusher, and he 
rolled it. The points of the 
roller ]>ressed a large portion of 
the seed in contact with the little 
moisture left in the land, llie 
soil from the crushed clods co- 
vered the seed, and it soon vege- 
tated, and produced a good crop, 
much beyond our expectation.
