LORD LEICESTER’S ELEVEN-COURSE SHIFT. 53 
cause or permit the land to accumulate a sufficient store of 
nitrogen and other fertilising qualities, and render it capable 
of producing the four years alternate course before referred to. 
With all due respect to his lordship’s opinion, we would 
suggest that the interval, before the four-course system is 
taken, should be extended to seven or eight years at least, 
thereby favouring the grasses, which pay (if they do), in pref- 
erence to the grain, which does not, 
His lordship appends a list of seeds which he states he has 
found, after various trials at Holkham, to be best adapted for 
securing a pasture on poor soils for a period of not less than 
six years. 
Subjoined are the quantities and varieties of seed per acre, 
the total cost at the prices given barely exceeding 13s, :—

His lordship goes on to say: “It is very desirable that the 
pasture should not be too closely fed by sheep during the 
summer months of the first two or three years, and it is better 
when practicable to mow the seeds the first year after laying 
down. The ryegrasses insure a sufficiency of herbage during
