This series consists of a fragmentary collection of outgoing correspondence generated by the commissioner, the chairman, the secretary and the rate expert of the Public Service Commission. Also included are telegrams and memos. These reading files, though usually destroyed by most state agencies, give an inside view into the thinking and planning of the Public Service Commission back in the early days when the trucking industry and the railroads were competing head to head for market domination and the Motor Carrier Act of 1929 and 1931 caused a great deal of confusion on the "hauling for hire" of passengers and the transporting of goods by common carriers. For other records pertaining to correspondence, see also Series 19, General Administrative Correspondence Files, of this sub group.
