Everyone took short cuts in Moscow. The tram numbers, except for the line round the boulevards, were frequently changed, and unless you felt like paying for a sledge or a cab you were bound to spend a good deal of time on foot. But once you were off the main streets you had to know (since it could scarcely be explained) the way. Street names soon ran out. You were faced by towering heaps of bricks and drain-pipes, or a lean-to which encroached on the pavement, or a steaming cowshed whose rotten planks seemed to breathe in and out under their own volition.
