that it can bo removed with the greatest facility. Another 6et of prickers are fitted into the 

 back of the muzzle, and act upon the under jaw of the animal when attempting t.> Book his crib. 

 The sharp points are fitted to the fixed curved bar L, which is secured to the inside of the 

 muzzle, and they are shielded or protected by the slotted or perforated bar M, which is con- 

 nected to the bar L by screws at N, working in slots in the bar If, thus allowing it t<> be 

 pressed downwards by the under jaw of the horse when sucking its crib, and thereby causing 

 the prickers to protrude. 



Improvement in Ox- Yokes. 



The annexed figures are representations of an improvement in ox-yokes, invented by 

 Heman B. Hiimtnon, of Bristolville, Ohio. The peculiarities of the invention consist in 

 placing a ferrule or plate having branched slots upon the end of the ox-bow, and in fasten- 

 ing to the top of the yoke a movable washer having a projection caused to fit into the branched 

 slots of the ferrule attached to the bow; by means of this combination the bow may l>e ele- 

 vated or depressed as desired, and fastened in any position. The construction of the several 

 parts will be understood by reference to the accompanying figures: a (fig. 1) represents one- 

 half of the yoke, with the bow-plate or ferrule and washer attached: eg (fig. 2) and c (fig. 3)
