The historian, with a vast chronological account of a people, parallels it with a skip trail which stops only at the salient items, and can follow at any time contemporary trails which lead him all over civilization at a particular epoch. There is a new profession of trail blazers, those who find delight in the task of establishing useful trails through the enormous mass of the common record. The inheritance from the master becomes, not only his additions to the world's record, but for his disciples the entire scaffolding by which they were erected.

Our ineptitude in getting at the record is largely caused by the artificiality of systems of indexing. When data of any sort are placed in storage, they are filed alphabetically or numerically, and information is found (when it is) by tracing it down from subclass to subclass. It can be in only one place, unless duplicates are used; one has to have rules as to which path will locate it, and the rules are cumbersome. Having found one item, moreover, one has to emerge from the system and re-enter on a new path.
The human mind does not work that way. It operates by association. With one item in its grasp, it snaps instantly to the next that is suggested by the association of thoughts, in accordance with some intricate web of trails carried by the cells of the brain. It has other characteristics, of course; trails that are not frequently followed are prone to fade, items are not fully permanent, memory is transitory. Yet the speed of action, the intricacy of trails, the detail of mental pictures, is awe-inspiring beyond all else in nature.

As the forest of Cross Timbers was now beginning to be seen in the distance, and fearing we might be troubled to find a passway through this brushy region, south of the Canadian, we forded this river on the 29th, without the slightest trouble, and very soon entered our former trail, a little west of Spring Valley. This gave a new and joyful impulse to our spirits; for we had been traveling over twenty days without even a trail, and through a region of which we knew absolutely nothing, except from what we could gather from our Comanche pilot. This trail, which our wagons had made the previous summer, was still visible, and henceforth there was an end to all misgivings.

I'd like to say that people people can change anything they want to; and that means everything in the world. Show me any country and there'll be people in it. And it's the people that make the country. People have got to stop pretending they're not on the world. People are running about following their little tracks. I am one of them. But we've all gotta stop just stop following our own little mouse trail. People can do anything; this is something that I'm beginning to learn. People are out there doing bad things to each other; it's because they've been dehumanized. It's time to take that humanity back into the centre of the ring and follow that for a time. Greed... it ain't going anywhere! They should have that on a big billboard across Times Square. Think on that. Without people you're nothing.

Pamela Travers appears and disappears as magically as the nanny she created. The New Yorker is the latest to discover the real Travers, the Australian who invented Mary Poppins 70 years ago. Travers told me in 1995, a year before her death, that she would talk of her work, but never of herself. In her lifetime, a biography was impossible, partly because she left so many false trails.
Luckily, she also left a paper trail of truth at her London home and in a Sydney library.
