about midnight
Think of tramping along in the pitch dark carrying a man hurt as badly as he is . '' `` Between you and me I do n't believe Frank will risk it . We can go as far as possible , and when it grows dark pull up . Along about midnight , if it stays clear , we ought to have the moon , and it 'll give us enough light to go on again . '' It proved to be just as Bluff had said , for when the wounded man had been carefully lifted and placed on the litter , with one of the boys ready to take hold of each corner , Frank set forth his plan . `` We 'll do the best we can , fellows , until it gets too dark to see well ; then we can lie down and rest for hours . When the moon gets fully up , so that the woods are light again , we 'll finish our tramp to the cabin .
