Another measure for longer lengths is the distance from the end of your nose, when your head is turned sharply to one side, to the end of your thumb when your arm is stretched straight out from the shoulder in the opposite direction. Measure and find out this distance for yourself by holding the very end of a ribbon, tape or rope with the left hand to the end of the nose, head turned to the left, and with the right hand run the fingers along the edge of the ribbon until it is stretched to arm's length. Marking the ribbon with a pin where the right thumb and forefinger have held it, measure the distance with a yard measure or rule from the end of the ribbon to the pin. This length will be about the same as the standard unit of length used in this country. When measuring a long length of goods, use the point held by the right hand as the starting point to be held by left hand. If you know the distance between the end of your little finger and the end of your thumb when they are stretched apart, the palm of the hand being flat, you can measure a distance such as the length of a table, shelf, pole, etc. When judging the height of a person, remember that the distance from the top of the head to the chin is about one-ninth of the height of the body. The distance between the middle fingers when the arms are stretched straight out from the shoulders is about equal to the height of the body. Another personal measure that is of value is the length of one's average pace or stride; that is, the distance from the toe of one boot to the toe of the other when walking a natural gait. It is also useful to know the average number of paces taken in walking a given distance, such as a mile, and the time required to make them. All of this information can be obtained in a very simple way. Measure off as accurately as possible 220 yards, which is one-eighth of a mile, or take a known distance, and pace it back and forth at least eight times, but not all in one day. Each time keep a record of the number of paces taken and the time required to pace the distance. Divide the sum of the paces by the number of times paced and the result will be the average number of paces for the distance. Then divide the whole distance by the average number of paces and get the average length of your pace. Divide the sum of the minutes spent in pacing the distance by the number of times paced, and get the average length of time required to walk the distance. When the average length of pace is known, the distance between two points can be quite accurately estimated by pacing, if the ground is open, level and solid. If up or down grade, if the ground is muddy or heavy, or there are other causes which retard the gait, a reduction must be made. None of the above methods for measuring are scientific, therefore are not accurate, but they are useful ways of measuring _approximately_ lengths and distances by means of a guide always at hand. 2.
