forward or back and forth, but the same rules hold good. 
Learn to know the height of a chair seat, a table, your 
own height, a room, a house, trees: by measuring and 
looking, and looking and measuring, you will accomplish 
much. 
To learn to judge weight begin by holding in your hand 
something that weighs a pound ; after holding it a few 
moments put it down and then take it up again always 
trying to sense the weight. Do not use your eyes, only 
your hand. Try a two pound weight, and so on. Then 
take up something else the weight of which you do not 
know and see if you can tell its weight. Practice, patience 
and memory are necessary in this work. 
There is another way of judging weight, one in which 
our eyes help us. Knowing how a pound of butter looks 
as to size we can judge the weight of a mass of butter by 
looking at it and comparing it mentally with what we 
know. We can follow this method in judging the weight 
of different goods, but as each kind when put in pound 
quantities looks more or less different from every other 
kind, experience, and knowledge of the character of the 
goods is necessary. A pound of butter and a pound of 
feathers do not make the same size bundle so the weight 
of each could not be judged by the same eye standard. 
By practice a Girl Scout should be able to do the follow- 
ing things in the way of judging height, weight and dis- 
tance :

a pole, water pipe or similar object. Distance of 
6, 10, 15, 25 and 100 feet. (This is useful in 
camera work.)
