With the above three arrivals on hand, it may be seen how great was the danger to which all concerned were exposed on account of the bold and open manner in which these parties had escaped from the land of the peculiar institution. Notwithstanding, a feeling of very great gratification existed in view of the success attending the new and adventurous modes of traveling. Indulging in reflections of this sort, the writer on going from his dinner that day to the anti-slavery office, to his surprise found an officer awaiting his coming. Said officer was of the mayor's police force. Before many moments had been allowed to pass, in which to conjecture his errand, the officer, evidently burdened with the importance of his mission, began to state his business substantially as follows:

"I have just received a telegraphic despatch from a slave-holder living in Maryland, informing me that six slaves had escaped from him, and that he had reason to believe that they were on their way to Philadelphia, and would come in the regular train direct from Harrisburg; furthermore I am requested to be at the depot on the arrival of the train to arrest the whole party, for whom a reward of $1300 is offered. Now I am not the man for this business. I would have nothing to do with the contemptible work of arresting fugitives. I'd rather help them off. What I am telling you is confidential. My object in coming to the office is simply to notify the Vigilance Committee so that they may be on the look-out for them at the depot this evening and get them out of danger as soon as possible. This is the way I feel about them; but I shall telegraph back that I will be on the look-out."

While the officer was giving this information he was listened to most attentively, and every word he uttered was carefully weighed. An air of truthfulness, however, was apparent; nevertheless he was a stranger and there was cause for great cautiousness. During the interview an unopened telegraphic despatch which had come to hand during the writer's absence, lay on the desk. Impressed with the belief that it might shed light on the officer's story, the first opportunity that offered, it was seized, opened, and it read as follows: (Copied from the original.)

HARRISBURG, May 31st, 1856.

WM. STILL, N. 5th St.:—I have sent via at two o'clock four large and two small hams.

JOS. C. BUSTILL.

Here there was no room for further doubt, but much need for vigilance. Although the despatch was not read to the officer, not that his story was doubted, but purely for prudential reasons, he was nevertheless given to understand, that it was about the same party, and that they would be duly looked after. It would hardly have been understood by the officer, had he been permitted to read it so guardedly was it worded, it was indeed dead language to all save the initiated. In one particular especially, relative to the depot where they were expected to arrive, the officer was in the dark, as his despatch pointed to the regular train, and of course to the depot at Eleventh and Market streets. The Underground Rail Road despatch on the contrary pointed to Broad and Callowhill streets "Via," i.e. Reading.

As notified, that evening the "four large and two small hams" arrived, and turned out to be of the very finest quality, just such as any trader would have paid the highest market price for. Being mindful of the great danger of the hour, there was felt to be more occasion just then for anxiety and watchfulness, than for cheering and hurrahing over the brave passengers. To provide for them in the usual manner, in view of the threatening aspect of affairs, could not be thought of. In this critical hour it devolved upon a member of the Committee, for the safety of all parties, to find new and separate places of accommodation, especially for the six known to be pursued. To be stored in other than private families would not answer. Three or four such were visited at once; after learning of the danger much sympathy was expressed, but one after another made excuses and refused. This was painful, for the parties had plenty of house room, were identified with the oppressed race, and on public meeting occasions made loud professions of devotion to the cause of the fugitive, &c. The memory of the hour and circumstances is still fresh.

Accommodations were finally procured for a number of the fugitives with a widow woman, (Ann Laws) whose opportunities for succor were far less than at the places where refusals had been met with. But Mrs. L. was kind-hearted, and nobly manifested a willingness to do all that she could for their safety. Of course the Committee felt bound to bear whatever expense might necessarily be incurred. Here some of the passengers were kept for several days, strictly private, long enough to give the slave-hunters full opportunity to tire themselves, and give up the chase in despair. Some belonging to the former arrivals had also to be similarly kept for the same reasons. Through careful management all were succored and cared for. Whilst much interesting information was obtained from these several arrivals: the incidents connected with their lives in Slavery, and when escaping were but briefly written out. Of this fourth arrival, however, the following intelligence will doubtless be highly gratifying to the friends of freedom, wherever the labors of the Underground Rail Road may be appreciated. The people round about Hagerstown, Maryland, may like to know how these "articles" got off so successfully, the circumstances of their escape having doubtless created some excitement in that region of the country.

Arrival No. 4. Charles Bird, George Dorsey, Angeline Brown, Albert Brown, Charles Brown and Jane Scott.

Charles was twenty-four years of age, quite dark, of quick motion, and ready speech, and in every way appearing as though he could take care of himself. He had occupied the condition of a farm laborer. This calling he concluded to forsake, not because he disliked farming, but simply to get rid of David Clargart, who professed to own him, and compelled him to work without pay, "for nothing." While Charles spoke favorably of Clargart as a man, to the extent, at all events, of testifying that he was not what was called a hard man, nevertheless Charles was so decidedly opposed to Slavery that he felt compelled to look out for himself. Serving another man on the no pay principle, at the same time liable to be flogged, and sold at the pleasure of another, Charles felt was worse than heathenish viewed in any light whatsoever. He was prepared therefore, to leave without delay. He had four sisters in the hands of Clargart, but what could he do for them but leave them to Providence.
