Traces are sometimes attached to the axle- 

 tree of two-wheel carriages for the purpose of 

 rendering the horse's draught more effectual 

 when in a direct line from the centre of the 

 wheels, but this is erroneous, because the ex- 

 treme length from the horse's collar to the 

 axletree, and the increased vibration of the 

 traces reduce the power of draught, and fatigue 

 the horse. All powers of draught have a 

 limit, beyond which, the operation of that 

 power diminishes. Traces should always be 

 attached to a splinter-bar.
