IBde HAMILTON 
Germ -Proof Water -Bag 
TAKES the place of the old-fashioned, dirty water bottle, because it is practically germ-proof 
and allows any kind of water to be drunk with perfect impunity. 
It is pronounced by experts as one of the greatest inventions of the war, and should be in 
universal use by the troops. 
THOUSANDS 
OF VALUABLE 
LIVES might 
easily be saved by 
its adoption. 
INVALUABLE 
IN TROPICAL 
COUNTRIES 
where the source 
of water supplies 
is doubtful. 
Ensures PURE 
WATER under 
all conditions of 
ACTIVE SER^ 
VICE. 
THE bags are inter- 
lined with canvas 
to prevent wastage of 
water, and also to keep 
the contents cool. 
THE bags fill very 
rapidly, and are 
easily cleansed. There 
is nothing to get out 
of order. Stagnant 
water drawn from shell 
craters, ditches, or 
wells, once it passes 
through the germ- 
proof filter, is freed 
from all germs. 
THE bags do not 
have to be tipped 
up to drink from. The 
water is drawn simply 
bv suction.

The following extract Is from the Editor of Land 4 Watir in his kit article (March 7th, 1918) : — " The design is so very simple that one wonders, 
on seeing the thing, why nobody thought of it before. In the case of the ordinary water-bottle, of course, the first necessity is to assure oneself that 
the contents are pure, for otherwise a water-bottle may become a first class disease trap, warranted to hand out enteric, dysentery, and other com- 
forts with every drink. But you may &1I this particular bottle with sewage, if it so please you, and still get a drink of germ-free filtered water. . . 
The bottle \i no more trouble to fill than an ordinary bottle, and no more trouble to empty ; neither is it any bulkier or heavier than an ordinary 
bottle. It is, as already remarked, so simple that it iii a wonder it has gone undiscovered so long, and it is one of the most valuable safeguards of 
health that the war has seen. . . . There has been nothing to surpass this scientifically designed water-bottle in value as a preservative of health 
among the troops, and it is to be hoped that every man proceeding on active service mil have one of these water-bottles to take with him.'*
