Final answer:
The Header, depicted by Lassiter in the provided text, goes in a direction that helps to steer the herd into a manageable position by creating a narrowing circle. He expertly turns the head of the herd inward, guiding it by skillful maneuvering and use of landscape, eventually rounding them up as they head back up the valley.
Step-by-step explanation:
The direction the Header goes after catching the steer is strategic and aimed at controlling the herd's movement. In the excerpts provided, it's clear that the rider, Lassiter, is attempting to maneuver the herd into a more manageable position. After initially riding parallel to the herd's position, he rides directly away, which helps to turn the head of the herd inward and create a narrowing circle. This technique is often used by cowhands to control large groups of cattle, such as a stampede, ensuring that they do not scatter and can be driven in a specific direction.
Lassiter's skillful riding demonstrates his understanding of how to herd steers. He uses the geography of the landscape to his advantage, riding to the eastern rise of the valley to wait for the herd before spurring his horse into action opposite the lead steers. His movements prompt the herd to change direction, eventually causing them to swing around and head back up the valley.
