The first edition of the Newcastle Morning Herald and Miners' Advocate appeared on 3 April 1876. The result of a merger in 1876 between the Newcastle Chronicle and Hunter River District News (1858-1876) and the Miners' Advocate and Northumberland Recorder (1873-1876), the paper's founder was John Miller Sweet. It was originally published three times per week.
The Herald's ornate masthead, which included a sketch of a colliery pit-top, remained for 104 years. It was replaced in 1980 when the paper's name was shortened to Newcastle Herald.
'Leathermouth is the nickname of Colonel Gantian, who has been engaged by Scotland Yard to look after the welfare of Paul, rule of a small East European kingdom, while he is on a visit to England. The king has made enemies in his own country, and the presence of some of them is soon made apparent to Leathermouth. The king and he are associated in some thrilling experiences, including attempts on their lives, but eventually they come through safely.'
