Step-by-step explanation:
The plan hatched by William, Roland, and Wat to earn a livelihood was for Venters to go to the village, secure a horse and some kind of a disguise or less striking apparel for Bess. Meanwhile, she would add to their store of gold. Then they would strike the long and perilous trail to ride out of Utah. If he couldn't fetch back a horse for her, they would make the giant sorrel carry double. The gold, a little food, saddle blankets, and Venters's guns were to compose the light outfit they would start with.
