The rapid expansion of the foreign trade of the United States seems likely to produce what years of argument have failed to do; that is, the. adoption of the metric system as the general standard for measurements. A hill now before Congress provides that this system shall be the official standard for the various departments of the government. If the bill becomes a law, and it has the support of many influential, commercial and scientific bodies, the general use of the system would follow as rapidly as existing business conditions could be adapted to it.

While the business of this country was almost entirely local, no great necessity seemed to require the change, but with the great increase in trade with foreign countries, most of which required custom and other trade documents expressed in the metric system, the difficulties accompanying the use of two systems have multiplied and given a new aspect to the question.

As the change is towards increased simplicity and ease in calculations and enumerations, commercial necessities will undoubtedly influence a more general recognition of its advantages. The younger generation, with the general training received by technical and other schools, will have no difficulties to contend with, and will undoubtedly welcome and assist in its adoption.

The recent receipt of several interesting articles from readers of this magazine, dealing with subjects already in preparation by regular writers, leads us to request those who contemplate contributing such articles to advise the editor of their title and scope before writing and sending them, thus avoiding duplication of the work. New articles are desired, and will be accepted when treating of subjects not already provided for. The method above indicated will avoid the rejection of articles that cannot be used for the reasons stated.

Several interesting articles that were to have been presented in this issue are omitted, owing to lack of space. They will be inserted in the May number. The size of the magazine will be enlarged at an early date, enabling an increased number of topics to be presented with each issue.
