- THE EGG CABINET
A correspondent (T. S.) informs us that a man has a cabinet for holding
birds' eggs. There are twelve drawers, and all-except the first drawer, which
only holds the catalog-are divided into cells by intersecting wooden strips,

Can you show how the drawers were divided-how many cells and strips
in each drawer? Give the smallest possible number in each case.
