300 Experiments upon Wheat, Barley, and Swedes. 
lowing gentlemen undertook to carry out the suggestions of the 
Committee : — The Right Hon. Earl Bathurst, the Rojal Agri- 
cultural College, Mr, E. Ruck, Mr. W. J. Edmonds, Mr. William 
Smith, Mr. Plumbe, and Mr. T. Little. The College undertooii 
to send out weighed quantities of the required manures, and to 
provide analyses, the Chamber paying for the manure and other 
expenses. 
Wide Drilling and Tillage Experiments upon Wheat, 
The usual width of drilling wheat being about 9 inches, it 
was resolved — (1) to omit every alternate row, leaving a sj)ace of 
18 inches between the rows ; (2) to omit two drills, and leave 
two, making a space of 27 inches between double rows 9 inches 
apart; (3) to omit two drills and leave two, forking the inter- 
spaces during the summer; (4) to attempt the cultivation of 
carrots or potatoes between wheat-rows arranged as just de- 
scribed ; (5) to try the effect of firmly pressing land with the 
foot in winter and spring. 
In carrying out these experiments the wheat was in some cases 
sown witti the drill in the usual manner, and the surplus rows 
were obliterated by the hand-hoe soon after the blades of corn 
appeared above ground. In other cases the drill was set so as to 
deposit the seed at the required width. 
The objects of these experiments were as follows : — To show 
(1) how far a free admission of air and light influences the 
growth of the wheat-plant; (2) how far interculture is beneficial 
or the reverse ; (3) the effect of thin seeding. 
Similar experiments upon barley were also undertaken with 
interesting results. The following is a list of the plots required 
for carrying out these trials : — 
2 plots in which 2 rows were alternately omitted and left. 
2 in which 2 rows were alternately omitted and left, the 
interspaces being forked twice through the summer. 
2 3, the same as the last, but with carrots or potatoes 
planted in the interspaces. 
2 ,, firmly pressed with the foot. 
2 „ untouched for comparison. 
' JVide DrUlimj and Interculture. — " In wide intervals," says 
Tull, " we can raise a good crop with less labour, less seed, no 
dung, no fallow ; but not without a competent quantity of earth, 
which is the least expensive of anything given to corn." Tull 
has had a few ardent followers, among whom the late Mr. Smith, 
of Lois Weedon, may be mentioned as a faithful disciple. Some 
encouraging results, obtained by Mr. J. A. Clarke from a field 
cultivated upon modified Tullian principles, were published in
