M. CH. MARTIN. 
I iutve devised a, lmy-rack and manger which removes these 
objections. It is a rectangular box, 1 meter 30 centimeters long, 
GO centimeters wide, and 25 degrees high. A hay-rack is the 
cover, and fixed to it by hinges ; its superior border is not above 
50 centimeters from the ground of the stable. 
When the cribber is taking his food from this hay-rack, lie 
first tries to crib, but having a point dlappui too low to allow 
a muscular contraction sufficient to lower the pharynx, aspiration 
of the air becomes impossible. Again, when he wishes to eat, to 
take hold of his food, he is^obliged to execute movements of the 
head upwards , and we know that cribbing is possible only with 
movements downwards. 
Thus placed, the cribber loses by degrees his bad habit, as the 
rack is too low, and also because he is obliged to return to the 
normal prehension with movements upwards. 
This motion is not exactly vertical; most animals perform side- 
wise, with an ascending curb. 
This rack is then made, with the required conditions to (1) 
prevent, (2) cure, (3) make cribbing impossible. 
1. Prevent. —All who have raised or observed horses, con¬ 
sider with reason, the horse which licks or bites the manger, as 
having a pre-disposition to cribbing; this animal attached to the 
hay-rack in question, may yet lick it, try to gnaw it, but certainly 
he cannot crib. 
(2) . Cure. —The horse who cribs since some time, either in 
taking hold of the straw or in resting his head, will, whatever his 
age may be, lose also this vicious habit, after having for several 
months fed from this hay-rack. 
(3) . Make it impossible. —Tne old cribber will try to find a 
rest, and not finding it, will lose the habit. 
XI. 
Colts raised in the stable often crib at fifteen and eio’hteen 
O 
months. A breeder showed me one which cribbed at ei<dit 
months, and had begun when but six ; he had, after being weaned, 
been placed in a stable where the manger was arranged for a 
horse of ordinary size.
