SHOP MEASUREMENTS GENERAL
Few of us stop to consider in these busy days of what is often called the "industrial era of the world's progress, " that all of the standards used today in making various measurements of distance, capacity and weight are of comparatively recent origin. From time immemorial there have been methods of measuring length, capacity and weight; but with few exceptions there were no definite standards by which the various arbitrary units employed by different nations could be checked for accuracy. Many of the units were based on the simplest physical comparisons. For example: If an Indian wished to state the distance between two points, he would say it was so many days' journey. In Asia, where the skins of animals were sewn up and used to carry wine and water, a quantity of liquid was referred to as so many skins of wine, etc. On the other hand, there is every reason to believe that thousands of years ago certain races of people had standards of weights and measures better than, or equal to, those we have today. The great pyramid at Geezeh, in Egypt, is an example of refinement of workmanship and measurements that has perhaps not been matched by any other structure before or since that time.
