SUBSIDIARY SERVICES Particulars of revenue, expenditure, and net revenue for the various subsidiary services are set out in Statement No. 9a, and the following table shows the variations in revenue and expenditure with last year :

The variations on the expenditure side reflect generally the rising costs of wages and materials. The most pronounced increase on the revenue side is in the road motor services. Since the relaxation of wartime controls, services have been reinstated and expanded. New services have also been inaugurated and some purchased from private operators.
