The Post Office. – The removal of the appurtenances of the city post office to the Spotswood Hotel took place, yesterday, in consequence of which there was a temporary suspension of the delivery of letters, and opening of mails. The clerks were busily occupied, yesterday, in effecting the transfer, and will doubtless be prepared this morning, to resume their official duties. The new post-office does not of course possess all the conveniences which pertain to the one just vacated, but it will do until the establishment and growth of our new Republic shall justify better arrangements.
