"_Dear Hadley_:--According to agreement, as entered into by us at our conference in old Marshall's garden, I now impart to you the following information, which you will receive at the hands of one of our most trustworthy associates. You will please note the contents of this communication, so as not to fail in the execution of that part of the transaction assigned to you, and then burn the letter immediately, that you may prevent the possibility of its falling into other hands, which would lead to the most disastrous consequences--perhaps to the destruction of our organization. When taken, bring the horses at once to the rendezvous, with such other valuables as may come in your possession; and be sure that everything is done secretly, and in such a manner as to avoid detection. Be bold and determined in resolution, but cautious and guarded in action. Yours, ---- ----, Capt." The captain's name was written in characters, as well as all the body of the letter, which Mr. Mandeville did not understand, and which were evidently to be intelligible only to the members of some band of villains, by whom the signs had been adopted as mediums of communication.

All his former prejudice against Hadley returned in ten-fold strength; for had he not the most positive proof of his villainy? Not a moment longer waited he for an interview, but with the letter carefully stowed away in a side pocket for future reference and use, he bent his steps back to his house, revolving in his mind how to proceed in the present emergency. That some great scheme of theft and robbery had been planned, with a design to be speedily executed, was evident from the contents of the letter; but where and when the act or acts were to be committed, it was impossible to tell, and consequently, a very difficult matter to decide upon a course of policy likely to thwart the designs of the rogues. After much reflection, Mr. Mandeville concluded it was best to lay the case before the magistrate and take legal advice how to proceed He did so. In a private conference with that functionary, they talked over the matter. The justice was a worthy man and a friend to Hadley, and though the evidence was overwhelming and nearly positive of his guilt, yet he could not find it in his heart to condemn the young man without a hearing, and was equally unable to get the consent of his mind to make the matter public, thereby injuring the reputation of his friend, until he could see and converse with him on the subject. He advised Mr. Mandeville thus:
