With Boone on the Frontier by Edward Stratemeyer

After the departure of Ezra Winship and Peter Parsons, affairs at the log cabin took on a more sober look than ever. Although but little was said on the subject all felt that the expedition that had been undertaken was a most serious one. Should the pioneers be led into ambush by the Indians it might be that not one of them would come back to tell the tale.

But with so much work to be done, the boys had no time for idle speculation. They felt the responsibility that had been thrust upon them, and they determined to do their duty to the best of their ability.
