The other rafts must by now be far ahead of them; and so he reminded the searchers and warned them that they must be leaving. They shot off some rifle shots, hoping to attract the child’s attention. But was Betty likely to guess what the rifle shots meant? “She’s not far off—can’t be,” Jim said. [139]
