Table for Use in Making Pedigrees. 



One or both of the parents of the numbers inside the parentheses came from the 

 number outside. This table, with the source numbers in connection with the matings, 

 enables one to trace the ancestry of any mating as far back, and the progeny as far 

 forward, as there are any records.

Explanation of the Tables. Matings of the same kind are grouped in summaries. 

 The (? parent is on the left and 'the ? on the right of the x , except when (R) is used, 

 which indicates a reciprocal. Below the line, beginning at the left, (R) when used = reci- 

 procal ; the number in heavy type (e.g. 470) is that of the mating ; the next number, or 

 numbers, indicate the progeny; the last number, or numbers, in square type (e.g. 26), 

 indicate the sources of the parents, the <r being on the left and the ? on the right when 

 two numbers are given. The numbers in the sources less than (470) refer to the tables 

 of the second instalment. The first line of totals gives the actual numbers and the 

 second the expectation.
