many of the ambulance men have their splendidly trained dogs for seeking
out wounded soldiers among the dead. They are also trained as guards and
watch-dogs and they become marvellously clever when used near the firing
lines. They carry water in the trenches and are trained in packs to
dismount enemy motorcyclists by pulling them from their machines. Dogs
also make splendid scouts, and excellent and reliable messengers when
not required to go too far.

These faithful friends of man, according to Buffon, are far more easily
taught than man, and more easily led "than any of the other animals, for
not only does the dog become educated in a short time, but even adapts
himself to the habits of those who control him." According to
circumstances, a dog may become a soldier, messenger, water-carrier, or
guard.

Not the least among the uses of war dogs is the curious practice of
sending them into the enemies' lines of cavalry to convey fire in order
to terrorise the horses and throw them into confusion. This practice has
been quite common in the past. Each dog is dressed in a cuirass of
leather and on his back is carefully strapped a pot of boiling, blazing
tar. Nothing so terrorises horses as the sight of approaching fire.

A small but valuable ally to man is the ferret. This little creature has
come into prominence more particularly during recent years, when the rat
infested trenches have made his services invaluable. These Hun-like
rats, devouring and devastating in their thirst for human blood, would
have forced the abandonment of many a front line trench but for the aid
of these trained ferrets, thousands of which have been daily employed on
the battle fronts.

The immense services rendered by carrier pigeons in the battle of the
Marne, not only to the military authorities, but also to the public at
large, will cause the civilised world to pay more attention to the
importance of these birds in the future. They carried all kinds of
messages to and from Paris during this memorable battle; in fact, they
have been used in all the battles as invaluable messengers.

Small animals, such as mice, canary birds, guinea pigs and rabbits are
used in trench warfare, becau
