Mr. W.P. Pearce, the clerk in charge of the .Post Office at Basseterre, St.Kitts, writing to the late Sir Edward Bacon on December 9th,1890, stated that the provisional stamps were generally surcharged at the printing office of 'The Advertiser', but the surcharge 'Halfpenny 'on half the ld carmine, was applied at the Post Office. He further stated that Revenue stamps were never authorised to prepay postage, and that they had never been used for that purpose. Mr. Pearce added in his note to Sir Edward Bacon:- 'Postage and Revenue stamps combined were issued for sale in the Leeward Islands on the 1st of last month (November 1890), and all the former issues of postage and revenue stamps called in on that date.'

A notice appeared at the end of June 1879,stating that St. Christopher, like the other Leeward Islands, would be admitted into the Postal Union on the 1st July following.
