seems to be in charge of this branch of
the work--I mean outdoor pictures."

"Yes, that's his line," said Joe. "Mr. Ringold attends to the
dramatic end of it. We have done work for both branches."

"So I was told," went on Mr. Alcando. "I asked to be assigned a
teacher, and offered to pay well for it. And Mr. Hadley at once
suggested that you two boys would be the very ones who could best
give me what I desired.

"He told me that you had just returned from the dangers of the
Mississippi flood section, and were up here resting. But I made so
bold upon myself to come here to entreat you to let me accompany
you to Panama."

Mr. Alcando came to a stop after his rather lengthy and excited
explanation.

"But Great Scott!" exclaimed Blake. "We don't know anything about
going to _Panama_. We haven't the least idea of going there, and
the first we've heard of it is the mention in this letter you
bring from Mr. Hadley."

"It sure is queer," said Joe. "I wonder if any of our mail--"

He was interrupted by the sound of rapid footsteps, and a
freckle-faced and red-haired boy, with a ragged straw hat, and no
shoes came running up.

"Say--say!" panted the urchin. "I'm glad I found you. Here's a

CHAPTER V

ANOTHER SURPRISE

envelope, preparatory to taking out the enclosure, Joe looked
sharply at the red-haired lad who had so unexpectedly delivered
it.

"How'd your father come to get our letter, Sam?" asked Joe, for
the lad was the son of a farmer, who lived neighbor to Mr. Baker.

"Sim Rolinson, the postmaster, give it to him, I guess,"
volunteered Sam. "Sim generally takes around the special delivery
letters himself, but he must have been busy when this one come in,
and he give it to pa. Anyhow, pa says he asked him to deliver it."

"Only he didn't do it," put in Joe. "I thought something was the
matter with our mail that we hadn't heard from New York lately.
Your father was carrying the letter around in his pocket."

"But he didn't mean to!" spoke Sam quickly. "He forgot all about
it until to-day, when he was changing his coat, and it fell out.
Then he made me scoot over here with it as fast as I c
