NATURAL INHERITANCE.
found wherever the book is opened, relate to the same family. The
open book is ruled so as to resemble the accompanying schedule,
which is drawn on a reduced scale on page 261. The printing within
the compartments of the schedule does not appear in the MS. books,
it is inserted here merely to show to whom each compartment refers.
It will be seen that the paternal ancestry are described in the left
page, the maternal in the right. The method of arrangement is
quite orderly, but not altogether uniform. To avoid an unpleasing
arrangement like a tree with branches, and which is very wasteful
of space, each grandparent and his own two parents are arranged in
a set of three compartments one above the other. There are, of
course, four grandparents and therefore four such sets in the
schedule. Reference to the examples A and B pages 252 and 253 will
show how these compartments are filled up. The rest of the Schedule
explains itself. The children of the pedigree are written below
the compartment assigned to the mother and her brothers and
sisters ; the spare spaces are of much occasional service, to receive
the overflow from some of the already tilled compartments as well
as for notes. It is astonishing how much can be got into such a
schedule by writing on ruled paper with the lines one-sixth of an
inch apart, which is not too close for use. Of course the writing
must be small, but it may be bold, and the figuros should be written
very distinctly.
For a less ambitious attempt, including the grandparents and
their fraternity, but not going further back, the left-hand page
would suffice, placing “ Children ” where “ Father " now stands,
“ Father’s Father ’’ for “ Father,” and so on throughout.
