The book is "How Russia Prepared. U.S.S.R. beyond the Urals." by Maurice Edelman, published in 1942.
The G.P.U., whose name was changed to N.K.V.D., with it's change of function. It has become something like a combination of our Ministry for Home Security and the road transport division of the Ministry of Transport.......the dissidents whom the G.P.U. interned were not allowed to decay in idleness. The internees were put to the task of improving Soviet communications, particularly by road and canal.
Ministry for Security and Transport, hmmmm. And not letting them decay in idleness.
