about, and a man with a few boys tear the turf in pieces about 3 inches 
square, and lay it, 8 or 9 inches apart, between the rows of wheat ; it is 
then trod in, which finishes the work. In the spring I sow 10 pounds 
an acre of white clover-seed — the first and second year I have always 
h;id plenty of feed, and the third year few people know it from old pas- 
ture. The price I pay is 8^. per acre for spreading, tearing, and laying 
the turf; and 4s. per acre for treading it in. In the autumn of 1842 
the men oflered to carry the turf on in baskets at 3.?. per acre, but, as 
they often lost half a day's work in consequence of rain, I paid them 4^., 
at which price they earned good wages. 
In one meadow of 8 acres I have taken nearly all the turf, with which 
I have laid down above 100 ; on some part of it I ploughed the turf fiv e 
separate times, but by giving the meadow a coat of dung after the turf is 
taken away, and a good rolling offer a frost, I find very little injury is 
done to the pasture. 
Perennial grasses spread rapidly by the roots, and seed at various 
times during the summer, consequently you cannot collect the seed of 
each sort : they also like to congregate together. Sinclair found thirty- 
two distinct species of grass in one square foot of turf in the Vale of 
Aylesbury. I transplanted a square foot from my meadow into my gar- 
den, and during the following summer I found twenty-eight. 
Landlords might very nmch improve their farms by getting their 
tenants to lay down in pasture, if only for a few years, some of their 
worn-out arable land, provided they have but an acre or two of good 
pasture from which to take their turf : I juy good, for if a good herbage 
once takes possession of the land, it keeps out bad.

XIIL— -Ort the Application of Sulphate of Ammonia to Wheat. 
By John Barton. 
As the effect of any system of management can only be known by com- 
paring the results of a great number of individual experiments, I venture 
to lay before the Society of Agriculture the result of an experiment just 
completed, . xhe application of Sulphate of Ammonia to wheat. 
In a field of o acres, consisting of gravel of indifTerent quality, worth 
perhaps 14s. or 15s. per acre, I sowed every other ridge, in the month 
of March last, with sulphate of ammonia : the whole quantity used was 
5 cwt. During the first tew weeks no difference was visible in the crop, 
but, as the spring advanced, the blades on the salted land became consi- 
derably darker in colour and more vigorous than the rest. Just before 
liarvesl I walked through the field with some agricultural friends, and 
Ave estimated the difference at 6 or 8 bushels per acre. As such esti- 
mates are, however, not to be depended on, I marked off' two spaces of
