Note 29, page 61: One of the regulations of the United States Army Pack Transportation Department says that packers must treat all the mules kindly, for a mule remembers kindness and never forgets injury. Packers must not even throw stones, to drive a mule into line. Of course, Boy Scouts know that kindness with animals always wins out over harshness, and that there is no greater cowardliness than the abuse of a helpless beast. Note 30, page 62: Highness and dryness, wood and water, and grazing for the animals are the requirements of the Scouts' camp on the pack trail. Note 31, page 63: By camp law bird or four-foot or other harmless animals within say two hundred yards of camp is safe from injury by man. This also prevents reckless shooting about camp. The wild life near camp is one of the chief charms of camping in the wilderness. No Scout wishes to leave a trail of blood and murder and suffering, to mark his progress through meadow and timber. Note 32, page 67: This division of watches or guards should be noted by Scouts. Bed-mates or bunkies should not follow one another on guard; for A wakes B when he crawls out; and after he has changed with B, and has slept two or three hours, he is waked again by B crawling in. But each Scout listed for guard duty should so be listed that he is not disturbed through at least two of the watches. CHAPTER VII Note 33, page 72: A "trail" is made up of "sign" or marks which show that something has passed that way. The overturning of pebbles and sticks, dryness and wetness of the spots where they were, dryness and hardness of the edges of footprints, grass pressed down, twigs of bushes broken, dew disturbed, water muddied, ant-hills crushed--all tell a tale to the Scout. He must be able to figure out what was the condition of the trail when the person or animal passed--and that will tell him how long ago the marks or sign were made. And the shape of the sign, and the way in which it is laid, tell what manner of person or animal passed, and how fast. Steps vary in size, and in pressure and in distance apart. A man at a very hurried walk is apt to leave a deeper toe-print, and a loaded horse sinks deeper than a light one. A good trailer is a good guesser, but he is a good guesser because he puts two and two together and knows that they make four. Note 34, page 74: A portion of a patrol on a scout should think to leave private signs, by marks in the dirt or on trees or by twigs bent or by little heaps of stones, which will tell their comrades what has been occurring. This the Indians were accustomed to do, especially in a strange country. To this day little stone-heaps are seen, in the plains and mountains of the West, marking where Indians had laid a trail.
