:20:04
	Watson this microscope
:20:06
	was last used for
examining microfilm.
:20:09
	I'm beginning to
see the pattern.
:20:11
	It stopped now.
:20:13
	Did you know
that the letters
:20:14
	of our soldiers overseas
:20:15
	are being
photographed on microfilm
:20:17
	so that one carrier pigeon
:20:18
	can carry the equivalent
of 18,000 letters?
:20:20
	Oh really?
:20:21
	We had a carrier
pigeon in the last war.
:20:23
	Back in 1915 belonging to
the Brigade Signal Corp.
:20:25
	Did you?
:20:26
	Yeah, the poor bird kept
flying round and round
:20:29
	in circles all day long.
:20:30
	Found out later on
that it was cross-eyed.
:20:32
	Tragic thing.
:20:35
	Where are you going, huh?
:20:40
	Oh dark room huh?
:20:43
	This is what I
was looking for.
:20:45
	This projector magnifies
tremendously
:20:47
	anything placed
on the slide
:20:49
	like this piece
of microfilm.
:20:55
	Understand?
:20:56
	Can't say I do
exactly, no.
:20:57
	Wait a minute.
:21:00
	I'll show you one
of his photographs.
:21:06
	Well it's that
match folder.
:21:08
	Why did he want to
photograph that for?
:21:09
	Probably to line
up his equipment
:21:11
	before he photographed
the document.
:21:14
	We got him Watson.
:21:15
	Oh have we?
:21:16
	Yes.
:21:17
	Come along.
:21:18
	All is clear as mud to me.
:21:21
	Just as I thought,
:21:22
	this document has been
reduced to microfilm
:21:24
	to make its
concealment possible.
:21:26
	Alfred Pettibone is a
most ingenious fellow.
:21:28
	A bulky document
:21:30
	is obviously
difficult to conceal
:21:31
	but two pages
of a state paper,
:21:33
	photographed
on microfilm,
:21:34
	would be reduced to a size
:21:36
	no larger than a stamp.
:21:38
	Slitting a match
folder with this...
:21:41
	with this razor blade...
:21:46
	Pettibone placed the now
minute document inside,
:21:48
	stuck it together again
:21:49
	and there he had it.
:21:50
	An American match folder,
rare in London
:21:52
	but completely
inconspicuous in
the United States.
:21:54
	Do you mean to say
were off to America
:21:55
	just to look for
a match folder?
:21:57
	It's a big country.
:21:58
	A big country Watson
