 And you needed good cutting horses because you couldn't hold a herd, a mixed herd particularly, and work it over five or six hours. Because they'd get hungry and they'd get thirsty and they'd quit working. They'd quit mamming up. That cow would worry more about grass and more about water than she did about her calf. And so you needed good horses and good men. And I call those cutting horses and cow horses early cowman's computers.
