Viewed from the front it is about 6 inches deep at one end, gradually tapering to a point at the other end. Running from front to back are a series of upright divisions, with the spaces separating them being halved each time, so that the last one is only the width and depth of a pencil lead.

Now all that needs to be done is to fill it up with all the stuff that lies around on the average desk (mine is like the scene following a plane crash).

Everything should find its own natural place by virtue of width and depth. Six inch dictionary at one end, sewing needles at the other; my collection of dead fies in tiny test tubes somewhere near the right hand side adjacent to the found teeth of small, unknown mammals; and just to the right of the diverse mangled rusty nails I have been collecting for the last few years.
