on and the
others released. New buildings were being erected at the airplane
plant, and although somewhat crippled, the business of manufacturing
these necessary engines of war was soon going on much as usual.

CHAPTER XI
A FONT OF TYPE

Mary Louise went into Josie O'Gorman's room and found the young girl
bent over a table on which were spread the disloyal circulars.

"You've been studying those things for nearly two weeks, Josie," she
said. "Have you made any discoveries?"

"I know a lot more about the circulars than I did," answered Josie.
"For instance, there are nineteen printing offices in Dorfield, and
only two of them have this kind of type."

"Oh, that's something, indeed!" cried Mary Louise. "One of the two
offices must have printed the circulars."

"No; the curious fact is that neither printed them," returned Josie,
regarding the circulars with a frown.

"How do you know?"

"It's an old style of type, not much in use at present," explained the
youthful detective. "In one printing office the case that contains this
type face hasn't been used for months and months. I found all the
compartments covered with dust a quarter of an inch thick. There wasn't
a trace of the type having been disturbed. I proved this by picking out
a piece of type, which scattered the dust and brought to light the
shining bodies of the other type in that compartment. So the circulars
could never have been printed from that case of type."

"But the other printing office?"

"Well, there they had a font of the same style of type, which is
occasionally used in job printing; but it's a small font and has only
twenty-four small a's. I rummaged the whole shop, and found none of the
type standing, out of the case. Another thing, they had only three
capital G's, and one of those was jammed and damaged. In the last
circular issued, no less than seven capital G's appear. In the first
one sent out I find fifty-eight small a's. All this convinces me the
circulars were issued from no regular printing office."

"Then how did it get printed?" asked Mary Louise.

"That's what puzzles me," confessed Josie. "Three of the four big
manufacturing concerns here have outfits and do their own printing--or
part of it, anyhow--and I don't mind saying I expected to find my clue
in one of those places, rather than in a regular printing office. But
I've made an exhaustive search, aided by the managers, and there's no
type resembling that used in the
