In connection with this Bristol mail robbery, the following are interesting particulars from the calendar of Treasury papers:--"Memorial of William Saunderson, clerk, to Sir Robert Walpole. Says he was author of an expedient to prevent the Bristol and other mails from being robbed. The scheme seems to have been to write with red ink on the foreside of all bank notes the name of the post town where they were posted, the day of the month, and also the addition of these words, viz.:--'From Bristol to London,' &c. These services (presumably Saunderson's) have been attended with great expense and loss of time, and no mail robberies have since been committed. Asks for compensation. Referred 11th April, 1728, to postmasters to report. May 23, 1728.--Affidavit of W. Saunderson, receiver, of Holford, West Somerset (probably the same person), that he sent a letter subscribed A.Z. to the Postmaster-General offering an expedient to prevent the robbing of the Bristol and other mails, and of the subsequent negotiations with the Post Office; has never received any reward. Mr. Carteret claimed the contrivance of the scheme wholly to himself. May 29th.--Postmaster-General's report of 17th April read: 'My Lords satisfied with the report.' Saunderson had no pretence to any reward. Scheme entirely formed at Post Office without assistance of Saunderson or anybody else. Saunderson called in, informed that my Lords adhere to Postmaster-General's report, and nothing more will be ordered therein." Stealing a letter or robbing the mail was a capital offence long after Hawkins and Sympson expiated their offences on the scaffold. Thus a notice from the General Post Office on the 24th July, 1767, issued in the _London Evening Post_, dated "From Tuesday, July 28th, to Thursday, July 30th, 1767," recited that--"Notice is hereby given that by an Act passed the last Session of Parliament, 'For amending certain Laws relating to the revenue of the Post Office, and for granting rates of postage for the conveyance of letters and packets between Great Britain and the Isle of Man, and within that Island,' it is enacted--That from and after the first day of November, 1767, if any person employed or afterwards to be employed in the Post Office shall 'secrete, embezzle, or destroy any letters, &c.,' 'every such offender, being thereof convicted, shall be deemed guilty of felony and shall suffer death as a felon, without benefit of clergy.' Also if any person or persons whatsoever shall rob any mail or mails, in which letters are sent or conveyed by post, although it shall not prove to be highway robbery or robbery committed in a dwelling-house, yet such offender or offenders shall be 'deemed guilty of felony, and shall suffer death as a felon, without benefit of clergy.'" In 1781 there was another robbery of the Bristol mail. The occurrence was set forth in detail in the following notice, which was issued on January 29th in that year:-- "General Post Office, Jan. 29, 1781.
