Thus, after summoning courage, he laid hold of the box a third time, and the Rubicon was passed. The car driver, totally ignorant of the contents of the box, drove to the number to which he was directed to take it--left it and went about his business. Now is a moment of intense interest--now of inexpressible delight. The box is opened, the straw removed, and the poor fellow is loosed; and is rejoicing, I will venture to say, as mortal never did rejoice, who had not been in similar peril. This particular friend was scarcely less overjoyed, however, and their joy did not abate for several hours; nor was it confined to themselves, for two invited members of the Vigilance Committee also partook of a full share. This box man was named Wm. Jones. He was boxed up in Baltimore by the friend who received him at the wharf, who did not come in the boat with him, but came in the cars and met him at the wharf. The trial in the box lasted just seventeen hours before victory was achieved. Jones was well cared for by the Vigilance Committee and sent on his way rejoicing, feeling that Resolution, Underground Rail Road, and Liberty were invaluable. On his way to Canada, he stopped at Albany, and the subjoined letter gives his view of things from that stand-point-- MR. STILL:--I take this opportunity of writing a few lines to you hoping that tha may find you in good health and femaly. i am well at present and doing well at present i am now in a store and getting sixteen dollars a month at the present. i feel very much o blige to you and your family for your kindnes to me while i was with you i have got a long without any trub le a tal. i am now in albany City. give my lov to mrs and mr miller and tel them i am very much a blige to them for there kind ns. give my lov to my Brother nore Jones tel him i should like to here from him very much and he must write. tel him to give my love to all of my perticnlar frends and tel them i should like to see them very much. tel him that he must come to see me for i want to see him for sum thing very perticler. please ansure this letter as soon as posabul and excuse me for not writting sooner as i don't write myself. no more at the present. WILLIAM JONES. derect to one hundred 125 lydus. stt His good friend returned to Baltimore the same day the box man started for the North, and immediately dispatched through the post the following brief letter, worded in Underground Rail Road parables: BALTIMO APRIL 16, 1859.
