[Illustration: _The use of hair in disguising the face is perfectly
useless unless the eyebrows are considerably changed. The brow and the
back of the head are also extremely important factors in the art of
disguise._

_The second picture shows the effect of "improving" the eyebrows of
the face on the left, and also of raising the hair on the brow, while
the third sketch shows what a difference the addition of a beard and
extra hair on the back of the head, can make._]

I remember meeting a man on the veldt in South Africa bronzed and
bearded, who came to me and said that he had been at school with one
of my name. As he thrust his hat back on his head I at once recognised
the brow which I had last seen at Charterhouse some twenty-five years
before, and the name and nickname at once sprang to my lips. "Why, you
are Liar Jones," I exclaimed. He said, "My name is Jones, but I was
not aware of the 'Liar.'"

"In altering your face you must remember that 'improved' eyebrows

Scouting_, p. 136.]

It fell to my lot at one time to live as a plumber in South-east
London, and I grew a small "goatee" beard, which was rather in vogue
amongst men of that class at that time.

One day, in walking past the Naval and Military Club in Piccadilly
in my workman's get-up, I passed an old friend, a major in the
Horse Artillery, and almost without thinking I accosted him by his
regimental nickname. He stared and wondered, and then supposed that I
had been a man in his battery, and could not believe his eyes when I
revealed my identity.

I was never suspected by those among whom I went, and with whom I
became intimate. I had nominally injured my arm in an accident and
carried it in a sling, and was thus unable to work, or what was also a
blessing, to join in fights in which my friends from time to time got
involved. My special companion was one Jim Bates, a carpenter. I lost
sight of him for some years, and when next I met him he was one of the
crowd at a
