What do You Think They Weighed?

Don't you think the following pretty good? I got it from an old man who says he won $5 for answering it years ago.

A man had an article weighing exactly forty pounds. He let it fall, and it broke into four pieces. But it was such a fortunate fall that the pieces were afterwards available for sale weights, and with them he could weigh any number of pounds from one to forty. How much did each piece weigh?

We do think it good. You ought to be able yourself to tell a good puzzle, for you have won some of our puzzle-prizes. The Table will publish the answer in a week or two.
