The identity of Mr.Blank, the influential Irishman of chapter 25, is a mystery. Miriam Shillingsburg published an article on him in the Mark Twain Journal in 1993. Ms.Shillingsburg theorizes that Mr. Blank is one of three possible candidates. None of them are Mr. Charles Casey of Pollerton Castle, Carlow, Ireland. It was with Mr. Casey that Sam Clemens had correspondence, May 15, 1876.:

“Of course I don't know what you hold, but I “call” you anyway! This being translated means: Tell me about this thing. Really & truly, now, is there a Twain Club?”

Mark is entranced by an altocumulous undulatus cloud show in the sky. He tells the history of the gold strike in Ballarat and the protests against the mining licensing tax. He then speaks of the refinements of Australian cities and the compact Ballarat English.

Twain travels from Adelaide to Horsham, in Victoria. He finds a cottonwood tree, of fine detail, like a Kodak, and a peppertree, like an impressionist painting. Outside of town is an agricultural college, the Longerenong Agricultural College, where they grow fruit trees in an arid environment. They had forty pupils, ten were farmers hoping to expand their skills, and the rest city boys getting a trade. The curricula included sheep shearing.

Twain spends most of this chapter illustrating the strengths and weaknesses of the aboriginal peoples, whom he believes are all but extinct. He never met one on his travels in Australia. He stresses the talents of these people, particularly their ability to discern minute details of the landscape, making them superlative hunters and trackers. He describes their ability in drawing as somewhere between De Maurier and Boticelli. Twain gets particular delight in discussing the aboriginal's tolerance for physical pain as well as their adroitness.
