Blunt reassures Ewart that he has not lost interest in his experiments and discoveries. He believes that the four varieties of horse distinguished by differences in their callosites is very important. He is pleased the grey arab given as a filly, has proved useful to Ewart and states that he will be unable to supply a friend of Ewart's with a bay Arabian mare due to the great demand for Arabian horses in the colonies.

Cockerell states that he wishes he could conduct experiments on horses in New Mexico as the conditions are very favourable. He mentions that Wilfred Blunt is also of the opinion that the native American horse may have lived to Columbian times. At present he is looking for mixed blood in the skulls of American horses. He points out that the old horses of Europe also had large heads. He also adds that he has found a copy of an aboriginal pictograph representing a man on a horse.
