The three ranch hands are working their way through a remote area of the ranch searching for strays that were missed in the fall gather.  Their gesture and motion are important elements in the composition.  As one can see, the lead horse and rider are cautiously making their way through the area.  An attentive and sure-footed horse of this nature is truly a prized possession.   Meanwhile, the other riders are more concerned with watching out for the lost strays.  There is a genuine display of responsiveness and great teamwork!
