METRIC EQ UI VA LENTS. 



Teachers may aid the introduction of the system by obtaining metric Models and 

 Apparatus, by hanging metric Charts upon tho walls, by making their own diagrams on 

 cloth a yard wide but a meter long, and by pointing to them with the graduated Sticks 

 of one or two meters in length. But the best of all agencies is the placing of some metric 

 measure, if only the 5-cent rule, in the hands of each pupil. 



An efficacious yet inexpensive way of diffusing elementary information' and arousing 

 curiosity respecting the system is to employ, in business correspondence, envelopes or 

 postal cards bearing a metric ruling along one edge. This ruling is done free of charge 

 by the Metric Bureau. 



14. Reduction to and from the Present System. Pending the 

 universal adoption of the metric system, it is often necessary to effect a 

 reduction to and from the older measures. 



The following Table of Equivalents is selected from the Tables on the 

 back of the "meter-yard," (Am. Met. Bureau, A, 444-448), in Foster and 

 Langley, (A, 263), and in Egleston, (A).
