250 Improvement in the Mode of Attaching Horses to Waggons. 
generally employed for farm purposes, and are found convenient and 
effective. 
The Belgian Government have applied the same principle to the 
yoking of the artillery-trains ; and it is certain that no guns of the same 
weight, and drawn by the same number of horses, would otherwise be 
able to traverse rough and uneven ground with the same facility. 
It may be remarked that provision is made to adjust the leverage to 
the power of each horse, so that the pairs may be always equally 
rarttched, if not in strength, at least in their effective efforts. To explain 
this more clearly, I liave subjoined a diagram representing the fore-train 
of a waggon adapted for five horses. It will be observed that spare 
holes are provided in the swing-bars to change the leverage. 
N.B. It is curious, but ncvcrlheless the case, that the whole team ol 
five horses is guided by a single small line tied to the middle of thf 
bridle-reins of the off-hand leader.
