Leonard Snowdon was reported to have arrived from London about 1737 to take charge of a school, but no further particulars are found concerning him.[1104] In 1757 William Thorne was reported as teaching poor children.[1105] He is one of the very few masters who taught in the Friends’ Schools, who advertised in the newspapers for pupils; such advertisement was possibly after he discontinued his services for the Board.[1106] The advertisement does, however, serve to give us more information as to his qualifications, than we could otherwise obtain. He was engaged at the time (1766) in conducting a writing, arithmetic, mathematics and merchants’ accounts school in Vidal’s Alley.[1107] At another time he advertised to teach writing, arithmetic, geometry, trigonometry, navigation, mensuration, surveying, guaging, and accounts.[1108] John Sitch (1758) is mentioned as receiving some of the scholars from William Johnson’s school.[1109] Joseph Pemberton was encouraged by the Board to start a school in 1758. Its location, as everything else concerning it, is very indefinite, being “in the upper part of town.”[1110] Other masters mentioned by various authors, and to whom reference has been made before, but whose history is almost unknown, are Rowland Richards, John Every, Marmaduke Pardo, John Walby, William Coggins, Benjamin Albertson, Hugh Foulke, John Chamberlain, Christian Dull, Daniel Price, Samuel Jones, and Samuel Evans.[1111] [Sidenote: Early schoolmasters at Byberry] [Sidenote: Character of Moor unsatisfactory to Friends] [Sidenote: No extreme cases of lawlessness among Quaker masters]
