126 The Diseases of Animals 
A sling is frequently used in caring for sick or in- 
jured animals. It consists of a wide strip of stout 
canvas, placed under the animal and supported from 
above, usually by means of a chain and tackle, so that 
the weight of the animal may be taken off his legs and 
he still be kept in an upright position. In using slings, 
it is rarely advisable to attempt to carry the entire 
weight of the animal. The sling is usually placed 
under the animal so that he can settle into it of his 
own accord when he gets tired. It is sometimes neces- 
sary to raise animals by means of slings, but the 
animals are rarely suspended in them for any length 
of time. 
When animals are unable to lie down for a consider- 
uble time, either from an injury or other cause, they 
will often rest themselves by leaning against supports. 
Wooden side supports can be placed in about the posi- 
tion that shafts would occupy on the horse. One should 
go across just in front of the breast, and, in‘ ease of an 
injury or lameness behind, another against the haunches. 
These supports should be protected by means of cloths 
or blankets. Animals are quick to take advantage of 
such things, and will get much relief by leaning against 
them. Such an arrangement is commonly ealled a 
‘Jean-to.” Animals lying down ean often be bolstered 
up into favorable positions by using sacks filled with 
bedding. 
As a general thing, grooming sick animals lightly 
with hand-rubbing gives them relief. Exceptions must 
be made in some nervous diseases, when it is necessary 
to keep the animal free from all disturbances,
