Five Years" Progress of Steam Cultivation.

is most hilly and uneven ; yet I am sup- 
ported by my last four years' i^ractice in 
expecting tlie produce of mine to be from 
one to two guineas per acre more than from 
either of them." 
Of course the fruits of a superior tillage ought to be manifested 
in a larger pioduce. Crops should be taken that horse-culture 
would not have given at all, and of all there should be a greater 
yield per acre. And, at the same time, there should be a per- 
manent amelioration of the soil, at least of strong land. Now, 
experiments in agriculture are of .necessity protracted, results 
being seldom of value unless deduced from the repeated observa- 
tions of years ; and the steam-plough is too young as yet to 
have furnished very extensive experience through several suc- 
cessive harvests. Still some very important and reliable instances 
of augmented production and improved condition of the land are 
already before the world ; and out of fifty good testimonies on 
this point, I will adduce a few specimens, premising that these 
are by no means more decided and satisfactory than the remainder, 
which considerations of type and paper compel me to withhold.

" The barley and oats after the steam-plough 
and gi-ubbing are decidedly better than after 
the horses — at least 3 sacks per acre ; also 
the tumif)s and swedes." 
On 300 acres arable, of mixed clay soil, 
some parts very tenacious, " I have been 
able to do away ■with 50 acres of dead fal- 
low, the same being now either in crop or 
seeds." 
" The barley-crop this year, on land steam- 
ploughed last winter and crossed in spring 
with the cultivator, is very much better rn 
quantity and quality than on land worked 
by horses, grown side by side." 
"I believe that it increases the value of 
strong land one-third, when it can be used 
l)roperly."
