rotten condition of the frog, with a fetid discharge 
from the cleft, which cleft is absent or nearly so in 
the healthy foot. 
Cause-—Due to contracted feet, or standing on 
rotten litter. 
Treatment. Careful shoeing and paring of rotten 
parts ; constant washing and attention to litter; and 
a temporary introduction of Stockholm tow and tar 
into the cleft, with or without I part to 10 of 
sulphate of copper. The cleft which appears with 
thrush will extend if neglected. To avoid thrush, 
the litter in the stable should be kept dry and clean. 
If it is desirable to save straw, great economy may 
be practised by the use of sawdust, which can 
generally be obtained at a nominal price. When 
this is spread thickly, all droppings removed daily, 
and the sawdust raked over every morning, it forms 
a clean, wholesome, and cheap substitute for straw, 
and does not require renewing for weeks. Sawdust 
manure is good for all soils on arable lands, and can 
be applied conveniently for top-dressing, or ploughed 
in with any crop, so that farmers who require their 
straw may use sawdust without hesitation. Tan 
and sawdust mixed also makes an excellent bed. 
Acute Thrush 
Cause —“ Stopping” the feet with cow dung, 
clay, and other beastliness is often the cause of 
thrush. : 
Treatment——Fomentations ; poultices ; antiseptic 
lotions ; mashes ; green food ; constant washing of 
the feet.
