Ridgeway writes that he is pleased that Ewart plans to go to Mexico to see the mustangs and states that he has full historical details about the horses which the Spaniards took to North America. He will insert Ewart's remarks regarding 'stockings' colouration into the draft of his book and refers to the death of Matthew Horace Hayes.

Ridgeway states that while he is happy to write in support of Ewart's application for £300 from the Carnegie Institute, he recommends that his case might be strengthened by waiting until after his book (The Origin and Influence of the Thoroughbred Horse) is published. He offers his support of Ewart's proposals for a research station, and suggests potential funders.
