Big Medicine was thinking of his own kid, and wondering what he was like, and if he remembered his dad.

He waved his hand in cordial farewell when the Kid looked back and wrinkled his nose in the adorable, Little-Doctor smile he had, and turned his attention to Deuce.
The Kid made straight for the box stall and told Silver hello over the half door.

Silver turned from gazing out of the window, and came forward expectantly, and the Kid told him to wait a minute and not be so impatience Then he climbed upon a box, got down a heavy canvas nose-bag with leather bottom, and from a secret receptacle behind the oats box he brought a paper bag of sugar and poured about a teacupful into the bag.
Daddy Chip had impressed upon him what would be the tragic consequences if he fed oats to Silver five times a day.

Silver would die, and it would be the Kid that killed him.

Daddy Chip had not said anything about sugar being fatal, however, and the Countess could not always stand guard over the sugar sack.
