The Post Office, in addition to its ordinary function of providing for the transmission of letters and packets, undertakes a number of subsidiary services. There are, of course, the telegraphs and telephones, the money order, postal order, and Savings Bank business, which have for many years been an integral part of the business of the Post Office. In recent years the Post Office has also undertaken the issue of certain local taxation licenses, and the payment of Old Age Pensions and Army Pensions. Now it has undertaken the sale of War Loan Stock, Exchequer Bonds, and War Savings Certificates. Apart from the telegraphs, telephones, and Savings Bank, however, these services form only a small part of the work of the Post Office. While the total cost of the ordinary postal services (i.e. excluding telegraphs, telephones, and Savings Bank) was in 1913-14 some £17,000,000, the cost of the subsidiary services was only about a million. The staff of officers has increased as follows:-- --------------+---------+---------+----------- Year. | Male. | Female. | Total. --------------+---------+---------+----------- 1880-1 | | | 80,000 1890-1 | 93,046 | 24,943 | 117,989 1900-1 | 137,807 | 35,377 | 173,184 1905-6 | 154,351 | 41,081 | 195,432 1910-11 | 166,073 | 46,741 | 212,814 1913-14 | 188,794 | 60,659 | 249,453[93] --------------+---------+---------+----------- Concurrently with the increase of the number of officers, the rate of wages has been revised on several occasions, as the result of the recommendations of Parliamentary and other Committees appointed to consider the question of Post Office wages. The cost of the increases of wages which have been granted as the result of these revisions, calculated on the basis of the staff at the dates of the respective revisions, without allowance for subsequent growth of force, is some £3,674,950 per annum.[94] The increase of the number of officers has, of course, increased the ultimate cost of each successive improvement in pay and conditions of service. The increased wages of the staff have naturally counterbalanced to some extent the economies resulting from the large increase of business. Since the first of these revisions, the Fawcett of 1881-2, the wages of the staff have absorbed a larger percentage of the total revenue of the postal services,[95] and the cost for staff per packet handled has increased from .288d. in 1880-1 to .329d. in 1890-1, and .418d. in 1913-14.[96] During the same period the cost of conveyance of postal packets has decreased from .131d. per packet other than a parcel in 1880-1, to .119d. in 1890-1, and .080d. in 1913-14.[97] The total cost of dealing with a postal packet other than a parcel has in recent years shown a small decrease. The cost in 1913-14 has been estimated at .520d.[98]
