A. A Genealogical Charf Sheef.

1. This sheet is 8'/2" x 11" and its purpose is to show graphically the genealogy of a

person or the pedigree of an animal. In the central space numbered "1," the name of the individual is written. In the spaces of the concentric bands, the names of the ancestors are placed, each band representing a generation. The figures in the spaces may be used as reference numbers.

2. The fan-shaped pedigree chart, while it eliminates the difficulty of spreading over too

much space, is less easy to read than 57.
