"We want food! Give us eggs, milk, beans, anything you've got! We're starving!"
The speaker wore chevrons on his arm, his companion red stripes on his shoulders.
"Whose place is this, old woman? Of course it's not empty. How about the light and that child there? Look here, confound it, we want to eat, and quick too. We’re coming in."
"Tell me what they call this ranch, woman?" the sergeant asked.
"Limon," the woman replied curtly, carrying wood to the fire and fanning the coals.
