Chapter XVII. Suspicious Strangers - Page 2

my advice is to go to Africa as soon as we can. In that way we'll leave them behind, and they won't have any chance to get your camera."

"But what I can't understand," said Tom, "is how they knew I was coming here. It was just as if that one man had been waiting in the telegraph office for me to appear. I'm sorry, now, that I mentioned to Ned where we were ordered to. But I didn't think."

"They probably knew, anyway," was Mr. Nestor's opinion. "I think this may explain it. The rival concern in New York has been keeping track of Mr. Period's movements. Probably they have a paid spy who may be in his employ. They knew when he sent you a telegram, what it contained, and where it was directed to. Then, of course, they knew you would call here for it. What they did not know was when you would come, and so they had to wait. That one spy was on guard, and, as soon as you came, he went and summoned Eckert, who was waiting somewhere in the neighborhood."

"Bless my detective story!" cried Mr. Damon. "What a state of affairs! They ought to be arrested, Tom."

"It would be useless," said Mr. Nestor. "They are probably far enough away by this time. Or else they have put others on Tom's track."

"I'll fight my own battles!" exclaimed the young inventor. "I don't go much on the police in a case like this, especially foreign police. Well, my camera is all right, so far," he went on, as he took a look at it, in the compartment where he kept it. "Some one must always remain near it, after this. But we'll soon start for Africa, to get some pictures of a native battle. I hope it isn't the red pygmies we have to photograph."

"Bless my shoe laces! Don't suggest such a thing," begged Mr. Damon, as he recalled the strenuous times when the dwarfs held the missionaries captive.

It was necessary to lay in some stores and provisions, and for this reason Tom could not at once head the airship for the African jungles. As she remained at anchor, just outside the city, crowds of Swiss people came out to look at the wonderful craft. But Tom and his companions took care that no one got aboard, and they kept a strict lookout for Americans, or Englishmen, thinking perhaps that Mr. Eckert, or the spy, might try to get the camera. However, they did not see them, and a few days after the receipt of the message from Mr. Period, having stocked up, they rose high into the air, and set out to cross the Mediterranean Sea for Africa. Tom laid a route over Tripoli, the Sahara Desert, the French Congo, and so into the Congo Free State. In his telegram, Mr. Period had said that the expected uprising was to take place near Stanley Falls, on the Congo River.

"And supposing it does not happen?" asked Mr. Damon. "What if the natives don't fight, Tom? You'll have your trip
