"There's no use asking me!" broke in the voice of Postmistress Jennie
herself. "You're not going to get that information, and the sooner you
understand that the better!"

"Say!" exclaimed the third voice--that of a man--if you don't tell us,
we'll--"

"Mail!" cried Jack, in a loud voice, as he sprang into the place through
the window. "I thought I was too early, but I guess I'm just in time," he
grimly added, as he swung around and faced two men who stood in front of
Jennie Blake.




CHAPTER VI


THE SECRET MINE

Whether the young postmistress, or the two strange men, was the more
surprised could not be told. Both Jennie and her annoyers started at the
sudden appearance of the young pony rider. Then looks of anger and
annoyance came over the faces of the two men, while Jennie appeared
relieved.

"What's the trouble?" asked Jack, and with a seemingly careless motion he
threw open his coat. In his belt was a revolver, which he carried more
because the regulations compelled him to than because he really thought he
would ever need it.
