"Sure enough they are the men now!" muttered Old King Brady. "Connors, these are the ones we want. Upon my soul I believe that boy is diving for them now."

"There go the Chinks!" exclaimed Connors, pointing to the boat which was pulling away from the pier.
"I found two metal cases down there. One last night those Chinamen opened. There was nothing in it but a lot of papers," said Ed.
