The second delivery, which commences about nine A.M., includes the correspondence received by the night mails from Ireland and France, and letters from the provinces and abroad which may arrive too late for the first delivery, as well as those posted in the nearer suburbs by 6.30 A.M., as specified in the tables for each district. The next nine deliveries are made hourly, and include all letters reaching the general post-office or the district offices in time for each despatch. The last delivery commences about 7.45 P.M. Each delivery within the town limits occupies about an hour from the time of its commencement, which may be averaged at from forty-five minutes to an hour from the time of despatch from the general post-office, according to the distance from St. Martin’s-le-Grand and the number of letters to be arranged by the letter-carriers for distribution. The provincial day mails are due at various times, and the letters are included in the next delivery after their arrival in London. The day mails from Ireland, France, and the continent generally, and the letters received from Brighton and other towns which have a late afternoon communication with London, are delivered the same evening in London and the suburbs within the six-mile circle. The suburban deliveries are regulated in a similar manner, with this difference, however, that in some of the less-thickly inhabited portions the deliveries are necessarily fewer. _THE POSTE RESTANTE._ There is more attention paid in England to this letter or paper inscription than there is with us. The “Poste Restante” being intended solely for the accommodation of strangers and travellers who have no permanent abode in London, letters for residence in London _must not be addressed_ “Post-Office till called for.” Letters addressed to “initials” or “fictitious names” cannot be received at the “Poste Restante.” If so addressed, they are returned to the writers. With us, little or no attention is paid to this important postal matter: hence, a letter addressed simply to “John Smith, Philadelphia,” without the word “Transient,” “or Poste Restante,” must necessarily take its winding way through all the phases of postal travel until it reaches the dead-letter office. We make another extract from the English “Postal Guide:”— “Letters for strangers are delivered from the Poste Restante for a period of two months; after which period they must have them addressed to their place of residence, in order that they may be sent by the letter-carriers. Letters for known residents in London, addressed to the ‘Poste Restante,’ are retained for one week only.
