Leaving these unfortunate people, we peeped into two cathedral churches,--that of the Church of England, or (as it is here called) the Protestant Episcopal Church, and that of the Church of Rome. Both buildings are very splendid. We had been in the former some time before we felt quite sure that we were not in a Popish place of worship, so papistical were its aspect and arrangements. It was evident that Puseyism, or Popery in some form, had there its throne and its sceptre. The avowedly Popish cathedral was crowded with worshippers; and, to the shame of Protestantism be it spoken, black and coloured people were _there_ seen intermingled with the whites in the performance of their religious ceremonies! The State of Maryland, of which Baltimore is the capital, having been first settled by a colony of Roman Catholics, might be expected to be a stronghold of Popery. Yet, it is not so. The adherents of that system are but a small minority of the population. Baltimore is, however, a stronghold of slavery. Here Garrison's indignation against the system was first kindled--here Frederick Douglas tasted some of its bitter draughts--and here Torrey died its victim. The following are specimens of the manner in which the trade in human flesh is carried on in this city:-- "NEGROES WANTED.--I have removed from my former residence. West Pratt-street, to my new establishment on Camden-street, immediately in the rear of the Railroad Depôt, where I am permanently located. Persons bringing Negroes by the cars will find it very convenient, as it is only a few yards from where the passengers get out. Those having Negroes for sale will find it to their advantage to call and see me, as I am at all times paying the highest prices in cash. "J. S. DONOVAN, Balt. Md." "o28--6m*." "CASH FOR FIVE HUNDRED NEGROES.--At the old establishment of Slatter's, No. 244, Pratt-street, Baltimore, between Sharp and Howard Streets, where the highest prices are paid, which is well known. We have large accommodations for Negroes, and always buying. Being regular shippers to New Orleans, persons should bring their property where no commissions are paid, as the owners lose it. All communications attended to promptly by addressing "H. F. SLATTER." "j5--6m*."
