ONE YEAR’S LEY. 31 
because it must be remembered that trefoil is fit to cut some 
ten days earlier than clover. 
On land which will not grow clover well, ten years’ interval 
is good, but where this cannot be entertained and trefoil mix. 
ture is undesirable, we recommend the perennial cow grass, or 
a mixture of half clover and half cow grass, which also app'ies 
to doubtful or clover-sick land. On heavy or retentive land 
the cow grass and clover will probably be found the best 
mixture, but on light lands the alsike, trefoil, and white clover 
mixture will do best. 
No sane man, however, would think of growing anything 
else when he was sure of his clover. 
Trefoil, or, as it is commonly,called, “the black and white 
mixture,” black inferring the black seed pods of the trefoil, 
and white the white suckling, is properly mixed by adding to 
24 lb. to 32 Ib. of trefoil, 2 1b. to 4 1b. of white suckling, and 6 lb. 
of perennial or pacey grass, or 12 lb. to 16 lb. of Italian. This 
is sometimes varied by adding to the white suckling, or 
replacing it with a little red suckling, which, if the spring 
happens to be wet and cold, will be found of great advantage. 
But if the spring be dry the red suckling will make a poor 
show. Where the feed is not required on a trefoil stubble, or 
if the land requires cleaning, it is an excellent plan to break it 
as soon as the hay is off, and, if one is fortunate enough 
to obtain sufficient moisture to bring the seeds up, sow during 
the month of July three bushels of spring tares with or without 
one bushel of barley bere. This will cover the land and 
produce either autumn feed, silage, hay, or soiling food. It 
comes on about Michaelmas, just at a time when second crop 
clovers are over, and cut daily and given with old hay is 
appreciated by every kind of stock. Should you not require 
the produce at all, plough all in, and such a course will be 
found equal to a heavy coat of manure, as the tares will collect 
nitrogen from the air and deposit it in your soil instead of the
