WIND-SUCKING. 
This is so intimately connected with crib-biting that it 
may properly be considered a modification of it; as it is 
accompanied by a want of condition, and the same bending 
of the neck, with the head drawn inward, is manifested, and 
the horse alternately opens and closes his lips, and a sound 
is produced similar to sucking air. The remedies attempted 
have been, tying up the head of the horse, except when 
feeding; and the application of a muzzle with sharp spikes 
bending towards the neck, which will prick him when draw¬ 
ing in his head. 
NOT LYING DOWN. 
Horses are sometimes prone to standing constantly; and 
some only lie down once in a fortnight, or even a longer 
period. When this is the case, they are generally liable to 
swellings in the limbs, and seldom able to go through much 
work. Such horses should, if possible, be put into a stable 
by themselves and left at liberty, and a well-made bed 
will sometimes tempt them to lie down. No means can be 
adopted to force the animal to take rest by lying down. 
When it is not possible to place him in a stable alone, an 
empty box should be constructed so that he may be left for 
the night unhaltered in it. I had a remarkably fine draught- 
horse that never was known to lie down, and yet be kept in 
good condition, and was not troubled with swelling in the 
limbs : but this is a rare occurrence. He sometimes fell 
down on his knees while asleep, but the groom always found 
him on his legs before he could reach the stable, although 
his house was next door. 
SLIPPING THE COLLAR. 
Some horses are very expert at getting out of their collar
