A little study will convince us that the metric system 

 has some advantages over other systems. It is a decimal 

 system throughout and can be used just as our decimal 

 system of coinage is used. For example, we may write 

 five dollars, three dimes, and five cents as $5.35 ; five 

 meters, two decimeters, one centimeter, and three milli- 

 meters may be written 5.213 meters. 



The Measurement of Length. All measurements of 

 length are simply the comparison of the length of the ob- 

 ject with some standard. If the measurement is to be 

 taken in the metric system, the comparison is with the 

 standard meter bar ; if by the English system, the compari- 

 son is with the standard yard at London.
