Practical Opiidoiis on the Effect 
Query 1 — Cr\ishing Clods. 
Query 2 — Strong Lands.

shire, Wales. 
It reduces clods perfectly in the driest sea- 
sons, although it sometimes has required a 
second application, more particularly for bar- 
ley after turni|)9. I have found it a most 
valuable im|^lement upon strong lands. 
I was so much satisfied with 
its results, both last year and the 
year before, when I tried it upon 
some of my wheals in the spring, 
that I have this year applied it to 
the whole of my wheats with the 
same beneficial results.

I can merely state that I have tried your 
clod'Crusher for breaking up rough, cloddy 
land, and also for preparing land for turnips, 
and have found it to answer very well, pro- 
vided the soil be in a dry state. 
G. Jacson, 
Barton Lodge, iiear 
Preston, Lancashire. 
I have only the experience of this season, 
during which I have found it a valuable imple- 
ment. 
Exceedingly useful. 
Rev. C. Glynk, 
Hawarden Rectory, 
Chester. 
I am very glad to have'this opportunity of 
bearing witness of the efficiency of your patent 
clod-crusher. I have used it entirely upon the 
strongest fallow, and am confident that with- 
out it, in a dry season, one particular field 
of blue clay in my occupation could not have 
been worked at all. I have lent it to many of 
my neighbours, who all express their unqua- 
lified approbation of its usefulness. 
W. JoBSON, 
ChilUngham Newtown, 
Wooler, 
Northumberland . 
I have found it most valuable in crushing 
clods, on soils which are tenacious, in pre- 
paring them for turnips in a dry season. Also 
for similar soils, after turnips, in a dry season. 
In the month of April, in preparing for bar- 
ley, I have found it a most useful and eflScient 
implement. It was my steward's opinion, in 
consequence of very dry spring seasons, some 
of my clay-soils, intended for green crops, 
would have remained fallow hadi been with- 
out the implement. 
I ploughed, harrowed, and 
clod-crushed a field of this de- 
scription of 24 acres, after turnips, 
and had a crop of barley of 6ii 
bushels per acre, by which I 
reckoned t he produce was nearly 
doubled. 
H. Cliffe, 
Bellevue, Enniscorthy, 
Ireland. 
I have used it in rolling wheat 
with good effect, and in prepar- 
ing light land for turnip-crops. 
XVIII. — On the Improvement of Marsh Land. 
By John Murton. 
Having tried an experiment on some second-rate marsh land in this 
part of the county, for the last ten years, and now being able to prove, 
to the satisfaction of every one, its great advantage to labourer, tenant, 
and landlord, and intending to continue my plan, I much regret my 
want of ability to do justice to it, with the view of persuading others to 
give it a trial. 
I have been in the occupation of upwards of 30O acres of marsh land, 
more or less subject to a coarse grass we call sword-grass, with the ditch- 
bank 2^ feet above the level of the land, and 3 feet above the water. 
To improve this gras.^^, or get stock to eat it, I have tried salt, lime, and 
chalk ; but as none of these answered to my satisfaction,^ in the year 1831 
I commenced, on a marsh of 4 acres, by first cutting the ant-hills, and
