Harris left England on the ship Candahar for South Australia in 1848, arriving at Port Adelaide in February 1849.
Lanyon and Harris's first shipments arrived within a month and they set up shop as ironmongers at 43 Hindley Street opposite the "Black Bull" hotel.
[2] Their partnership was dissolved in March 1855,[3] and Lanyon left South Australia by the barque Iris for London, where he started in business as a purchasing agent, servicing Harris and other Australian merchants.
They began selling off stock at discounted prices in March 1866[6] and the partnership was dissolved in August of that year, when it was revealed Harris had been a silent partner.
Harris and family left Adelaide by SS Balclutha on 14 January 1867,[9] for Melbourne, and thence to London.
