He goes to work in another way.

The truth is that he is a dangerous monomaniac, and his one idea
is to ruin the man who owns him. With this object in view
he will display a talent for getting into trouble and a genius for dying
that are almost incredible.

If a mob of sheep see a bush fire closing round them, do they run away
out of danger? Not at all, they rush round and round in a ring
till the fire burns them up. If they are in a river-bed,
with a howling flood coming down, they will stubbornly refuse
to cross three inches of water to save themselves. Dogs may bark
and men may shriek, but the sheep won't move. They will wait there
till the flood comes and drowns them all, and then their corpses
go down the river on their backs with their feet in the air.

A mob will crawl along a road slowly enough to exasperate a snail,
but let a lamb get away in a bit of rough country,
and a racehorse can't head him back again. If sheep are put into
a big paddock with water in three corners of it, they will resolutely
crowd into the fourth, and die of thirst.

When being counted out at a gate, if a scrap of bark be left on the ground
in the gateway, they will refuse to step over it until dogs and men
have sweated and toiled and sworn and "heeled 'em up", and "spoke to 'em",
and fairly jammed them at it. At last one will gather courage,
rush at the fancied obstacle, spring over it about six feet in the air,
and dart away. The next does exactly the same, but jumps a bit higher.
Then comes a rush of them following one another in wild bounds
like antelopes, until one overjumps himself and alights on his head.
