The amount of these savings can only be roughly surmised; but in 1912, Mr. David J. Lewis estimated that they would amount to at least 40% of the total operating expenses. In this connection, it may be remarked in passing that Mr. Lewis's qualifications for throwing light upon the express service problem include not only theoretical knowledge gained by years of study of the problem, both here and abroad; but also practical knowledge of ways and means, as attested by general belief that the establishment of a parcel-post in the United States was due to his analyses more than to the efforts of any other one man; and also by the fact that when the Government in 1918 assumed responsibility for the management of the telephone and telegraph systems of the land, Mr. Lewis was made, and at the time of writing is, the general manager in charge of those systems while under Government control. Certainly, in view of the economies enumerated above as inherent in Government ownership and control of the express companies, on the face of it Mr. Lewis's statement seems extremely reasonable. THE CONSEQUENT REDUCTION IN RATES So that, if Mr. Lewis's estimate were accurate, and remembering that the operating expenses of the express companies in 1917 represented one-half of the total charges made by the express companies for transportation, a reduction of 20% in the express rates should accompany the acquisition of the express companies by the Government, other things being equal. But other things are not equal. Lower rates mean increased business; and in an agency which has developed the field at its disposal so inadequately as have the express companies, each additional unit of business can be handled at a lower cost and hence at a greater profit than each previous unit. This consideration was the primary one advanced by the Interstate Commerce Commission in ordering 16% reduction in the express rates in 1914. So that, the lower amount of profit per parcel being counterbalanced by a greater number of parcels, the economy in a Government postal express should be represented by a lowering of express rates anywhere from 25% to 35% of the present rates.
