12 BACK CHAIN. 



the following very simple rule : — bring the chin of the horse 

 to the top edge of the manger; pass the loose end of the 

 head collar shank through the ring, or over and behind the 

 roller fixed at the bottom of the manger ; hold the head of the 

 animal firmly, and let the whole length of the shank pass down- 

 wards ; and that part of the loose end which lies upon the 

 ground (if any) is more of the shank than is required : all 

 additional length, (or length not upon the stretch when the 

 chin of the horse rests upon the manger,) is dangerous. It is 

 obvious that when the animal is laid down, and the head flat 

 upon the straw, the clog will be drawn close to the roller, and 

 that when the animal stands up the head may be moved up- 

 wards and downwards and laterally with the greatest freedom. 

 All length of collar shank, we may again observe, in addition to 

 the length stated, is unnecessary, and may be the cause of 

 mischief from becoming entangled amongst the limbs. 



Rack Chain. — The E-ack Chain should be eighteen or twenty 

 inches in length. One end of the chain hangs loose, while the 

 other is made secure to the wood work a little below the bottom 

 of the hay rack. The loose end of this chain should terminate 



as shown in the annexed 

 Fig. 3. ^ engraving. It is a com- 



mon practice to have a 

 hook in place of the end 

 as represented ; but a 

 hook is dangerous, espe- 

 cially to young horses. 

 I have known a common 

 hook to tear open a lip or an eyelid. Accidents of this 

 kind, however, cannot occur if the chain terminates as shown 

 above ; at least they cannot be supposed so likely to occur.
