Also in 1858 Barrow left the "Register" to become editor, manager and co-founder of "The South Australian Advertiser", whose first issue appeared on 12 July 1858. The first number of the "Weekly Chronicle" came out five days later, and in 1863 the "Express" was started as an evening paper. Though these papers were conducted with ability, the controlling company did not prosper, and it was wound up in 1864. The papers passed into the hands of a proprietary of eight persons of whom Barrow was one, and in 1871 Barrow and Thomas King became the sole proprietors. Barrow was editor of the "Advertiser" until his final illness and death a few months later.
