"2. I want each horse to be of natural good temper and disposition.
"3. I want each to be free from all tricks, and perfectly sound.
"4. I want the two horses to be well matched in size, appearance, temper, and action. The color is of less importance.
"5. I want them to move and act together as one horse.
"And if the horses you offer are such, and if you choose to bring on the horse 'Morris Miller' at my expense and risk, and the other horse at your own expense and risk, I will take 'Morris Miller' at $5000; and if the other horse shall prove satisfactory to Mingo and me on an opportunity of trial for a week or two, to be determined with reference to the weather and my being in town, I will give $5000 more and the pony for the other horse.
"Of course, I do not want to try one horse alone, and in doing so rely upon your representation that the other horse will suit, and that the two will work together as you say.
"I enclose check for $5000, which you can take if you approve these terms, but are to return without using it if you do not affirm these terms.
Yours,
"S. J. Tilden."
