"Why, yes, it is," returned Ralph, promptly. "Where did you get it?" he went on, in surprise, for he had thought the blade safe in his own pocket.

"Jess where you dropped it a couple of hours ago," returned Uriah d.i.c.ks, eagerly. "In the post office."

"The post office? I haven't been in the post office since yesterday."

"What are you doing out so early in the morning?" asked the constable.

"My mother is sick, and I have been over to Dr. Foley's for medicine for her."

"And you weren't near the post office?"

"Oh, yes, I was only a few hundred feet away when the explosion took place."

"There, didn't I say I saw him in the crowd?" exclaimed Uriah, eagerly.

"What were you doing in the crowd?"

"I wanted to see what was up."

"You didn't stay very long," said the constable, dryly.

"I couldn't. Mother was waiting for me."

"You are quite sure you weren't in the post office just before the explosion occurred?"

"Why, of course I wasn't in the place! What are you driving at?"

"We found the pocketknife in the building--found it not ten feet from the wrecked safe. It had been used, evidently, for ripping open some sealed packages."

"My knife!" e.j.a.c.u.l.a.t.ed Ralph.

"Exactly, Ralph," put in Bart Hayc.o.c.k. "But don't think I believe you guilty, my boy," he went on, feelingly.

"Guilty of what?"

"Robbin' the post office!" cried Uriah d.i.c.ks. "He is guilty to my way of thinkin'!"

"Robbing the post office!" e.j.a.c.u.l.a.t.ed Ralph.

"That's it, Ralph," said the constable, seriously. "It has been discovered that there were two men and a boy, and they think you were the boy."

"Me!" Ralph could hardly believe his ears. "Oh, Rodman, you don't mean it?"

"He does mean it!" said Uriah, sharply. "Wasn't your knife found there?"

"I must have dropped the knife in the office yesterday when I was hanging up Mr. Dunham's circulars."

"Did you use the knife then?" asked Bart Hayc.o.c.k.

Ralph thought for a moment.

"Yes, I did. The cord was too long, and I remember taking out my knife and cutting it."

"That wouldn't put the knife inside the postmaster's office," said Uriah.

Ralph looked at the knife again. It was really his--with his name carved on the handle. There was no disputing that point.

"I can't understand it," he said. "But I can give you my word of honor that I was not inside the building to-night."

"I guess Benjamin Hooker ain't taking your word for it," grumbled Uriah d.i.c.ks. "He is responsible to the Government, an' he's goin' to find out who robbed him, that's what he's goin' to do!"

"You had better come with me," said Jack Rodman. "You can tell your story to Mr. Hooker and to Squire Paget."

"Better make a search around here first," suggested Uriah. "The men that helped do the robbin' may be hiding here. Bart and I can hold Ralph so he don't run away."

CHAPTER XIX.

ABOUT THE ROBBERY.

If Ralph had been astonished before, he was doubly so now. He looked from one to another of the men in amazement.

"Do you really think I am one of the thieves?" he gasped.

"It's mighty suspicious," responded Jack Rodman. "You were seen in the neighborhood of the post office to-night, and then this knife business is a clew."

"I don't think Ralph will run away," said Bart Hayc.o.c.k. "I myself think he is innocent."

"Thank you for those words," said the boy. "I am innocent."

"Then you have no objections to our making a search about here," said the constable.

"Not any objection whatever," said Ralph, promptly. "Search where you please."

"I'll help you," said Uriah to the constable.

"Hadn't you better hold me tight?" suggested Ralph, with a sarcasm which was entirely lost on the miserly storekeeper.

"Well, I dunno," hesitated Uriah.

"I will see to it that he doesn't run away," said the blacksmith. "This makes me sick, Ralph," he added, in a low tone. "I know you are as innocent as a babe. That post office was robbed by professionals."

The constable and Uriah knocked on the cottage door and Mrs. Nelson let them in. She was greatly surprised when Jack Rodman declared his errand.

"Ralph is indeed innocent!" she exclaimed. "You may search the premises all you please."
