The Morning Post of 14 September gave an account of the Australian, Gundersen.
"There was a hurried pro-rata distribution of the prize-fund, in which those who happened to be present participated, and Mr. Gundersen himself succeeded in getting away to Christiana at a cost of semi-starvation and extraordinary fatigue, for the train was six days on what should have been a 36 hours" journey, and during that time he had only two meals and ten hours sleep".
