HEAT AND FLIES.

danger is to be apprehended from sheep being long exposed 
to rain. But in winter, weak sheep are very liable to be 
affected by their fleece getting drenched with rain, without 
an opportunity of drying themselves. When such, however, 
is the case, they must be taken into a barn or shed, to enable 
them to get dry, otherwise disease is sure to be induced. 
HEAT Am FLIES. 
In low and flat localities without shelter, sheep are fre¬ 
quently subjected to the oppressive heat of the sun, and 
likewise to the attacks of flies and various other tormenting 
insects, and even when they have shelter in flats, still they 
are not free from these pests. It is very common for these 
insects to deposit their eggs at the roots of the horns, or 
other parts about the head, as well as under the tail, which 
in the course of time will change into the grub or larva 
state. It is the duty of the shepherd to see that sheep are 
free from these, and to destroy their eggs when he finds them. 
This is most effectually done by the following ointment, which 
he must apply on the places where eggs are deposited :— 
Mercurial ointment . . 1 ounce, 
Resin, finely ground . .1 ounce, 
Hogs’ lard . . .3 ounces, 
Let the lard be melted in an earthen or other pot, and the 
powdered resin added, and when properly incorporated, let 
the ointment be put in, and the whole stirred until cold, to 
prevent the mercury from falling to the bottom. A very 
small portion of the above, well rubbed on the parts, will 
have the desired effect. 
As a preventive, the head and tail may be rubbed with 
the following composition :— 
Tar .... 1 pint 
Train-oil . \ gallon.
