taken and called a gram, which is about equal to 15 of our 
grains. 
All peoples find it necessary in the house, out in the 
open and in nearly all forms of occupation to measure 
and weigh in order to accomplish their work. 
It is part of a Scout's preparedness to know how to 
measure and weigh, and how to judge measurements and 
numbers without using measures and weights. 
There are rules for determining length and weight, and 
it is important to understand them. Measuring a distance 
means to find out the length of the straight line from one 
point to another. To get a sraight line in the open when 
walking fix the eyes upon two objects directly in front, 
one nearer and smaller than the other. With eyes high 
walk toward these objects keeping them always in line. 
When approaching the first one choose another to take 
its place in line with it and the second. Always have two 
objects in direct line with the eyes. 
This method can be used in marching, rowing, swim- 
ming, and when staking out the points of triangles for 
measuring distance and height, as it will give the shortest 
distance between two points. 
There are three general methods of measuring distance 
accurately. (1) chaining or taping; (2) telemetry, and 
(3) triangulation. Less accurate means of measuring are 
by sound, pacing and timing. 
(1) Chaining and Taping. The regulation chain or 
tape used by surveyors is 100 feet long. A Scout may 
use a shorter line but must follow the same rules. 
Three things must be kept in mind when using a line, 
a. The straight distance between two points is to be ob- 
tained. b. The point where the end of the line comes 
each time must be marked, e. The line must be stretched 
tight. 
This method can be used in measuring off the distance
