Practical Agriculture. 
manures and feeding-stuffs are employed to enhance the yield cl> 
grain and augment the production of meat, milk, butter, cheea 
and wool ; how public spirit and emulation in the nationa 
county, and local exhibitions have promoted the improvement ( 
every breed of cattle, horses, sheep, and swine. And he ma 
treat still more concisely of prices and of the methods of corr 
mercial transactions by which the farmers' raw materials, motive 
powers, tools, and plant, are purchased, and by which the pn 
ducts of his land and premises are disposed of and distribute 
to consumers. 
Climate. The diversified and fickle climate of England and Wales m; 
be described in brief by reference to Tables of temperature, rai: 
fall, atmospheric moisture, and prevailing winds. 
Temi)eiatuiL. It will be observed that the range of the thermometer is mui 
shorter in the western than in the eastern districts ; the differen 
between the January and the July temperature being, for instant 
only 18'3 degrees at Truro, in Cornwall, while it is 29"6 degre 
at Cobham, in Kent ; and, again, only 21 "1 degrees at Lancasti 
while it is 30"1 at York. The differences between day and nig 
temperatures are quite as marked.

Thus, while the mean temperatures of two counties, suci: 
Cornwall and Middlesex, vary only 1"2 degrees in summer, tl 
are 7 degrees difference between their mean daily ranges; >T a 
at sunrise, in summer, the air in Cornwall is 2^ degrees war t 
than it is in Middlesex, but the extreme heat of the day in Cd- . 
wall falls 4^ degrees short of that in Middlesex. 
As a general rule, the annual temperature of England decrc *8 , 
one degree for every 111 miles from south to north, and >e 
degree for every GG miles from west to east, while the ir n 
temperature of the middle of England is from 2 to 4 deg 's
