trucks are a great benefit wherever they can be used. In 
any of the treatments given, rest will accomplish much,

A disease which often affects work horses is azoturia. 
This is often called Monday morning sickness, due to the 
fact that it is an affliction which troubles the horses when 
they have been off work and are suddenly put into work 
again. It is usually due to heavy feeding when idle. It

in heaving flanks, sweaty condition, dilated nostrils, and 
pinched loin. The muscles become swollen and rigid and 
the subject moves stiffly or unsteadily. If any of the
