o'clock
The Colonel 's was a bad case . But he was a giant for strength and `` sound as a dollar , '' as the Boy reminded him , `` except for this little bother with your eyes , and you 're a whole heap better already . '' At a very slow rate they plodded along . They had got into a region where there was no timber ; but , as they could n't camp without a fire , they took an extra rest that day at four o'clock , and regaled themselves on some cold grub . Then they took up the line of march again . But they had been going only about half an hour when the Colonel suddenly , without warning , stopped pushing the sled , and stood stock-still on the trail . The Boy , feeling the removal of the pressure , looked round , went back to him , and found nothing in particular was the matter , but he just thought he would n't go any further .
