them at the moment when the shark was
busy with the horse, attack 1t and Kill 1T at
close quarters. All this had to be done
within the limits Of an angle of twenty de-
gress which limits the reach of the camera.
This was his under taking, and to realize it,
he had TO wait. He had to wait till a shark APP
preached the horse turned and suddenly rails
lug his hands aloft, the negro Owed head first
into the crystalline waters toward a figure
that approached the horse. The camera
began to operate. When the man found
himself confronting the monster, there was n
rapid movement of arms and legs. The man
was underneath. The animal, lashing its
tail with terrible violence, turned over right
ed itself again, stiffened out and commenced
to sink slowly. All was over. The knife
had done it's work and a moment later the
negro appeared smiling on the surface.
Up through the tube came a voice which
said cit was all useless" The swimmer had
not calculated with exactness the place for
the struggle and had killed the shark out Of
the cameras range. 1t was necessary to do
it all over again.
The crisis of the expedition had come. 1t
WIS necessary 10 get this picture somehow
and the natives declared that the sharks
might leave at any moment as they had come
especially since one of their number had
been killed. Impelled by this problem and
the possibility of losing the opportunity,
Ernest Williamson decided to undress, anoint
himself with whale oil in the native fashion,
arm himself with Il sharp knife md proceed,
in spite of the protests of his companions,
to kill another shark. AS a result we can
now see a moving-picture view Of o mortal
struggle between man and the scourge Of
the seas.
The humber of uses which can be made of
this apparatus is simply limitless. Not only
has it made it possible to descend into the
hidden regions of the ocean and study IN its
habitat the marvellous fauna Of the sen, its
wonderful flora, its indescribable colOurings,
which 1t is needless to say, can lever be
within the reach Of us; but by means of its
combination with submarine photography,
we can place all Of these things before the
eyes of the public.
The Williamson submarine tube may be
extended, according to capable engineers,
to penetrate to depths Of 500 feet. But at
present its limit is $50 feet.
Aside from the new possibilities opened to
O~ceanOgraphic science, aside from the new
light conditions which it will reveal and
which will doubtless find prompt application
to the arts; aside from the new regions thus

and sport, this apparatus will be of great
practical utility in examining and repairing
ships at sea, submarine cables and construc-
tion work, as we'll as in salvaging sunken
treasure. It's inventor has prepared a long
list of shipwrecks of vessels carrying millions
of dollars which are supposed to lie at
accessible depths and hopes to be able to
recover the treasure from many of them.
But however all this May be, the fact that
a great part of the veil which covers the
mystery of the seas has been rent and iudg-
ing by the universal interest that has been
aroused by the marvellous submarine moving
picture views recently shown in the theatres,
all of the elements of that mixture known as
the general public have derived the keenest
pleasure in gazing at the heretofore hidden
realms of Neptune.-hapert Anterican m
