DIMENSIONS AND STRUCTURAL DETAILS. 103 
In an empirical fashion I have gathered these variants into groups for 
comparison by extracting a definite index-figure as the result of divid- 
ing the width by the distance. We then find one large group in which 
the width exceeds the distance, a smaller group of 3 pieces in which 
they are equal, and a final group of 3 pieces in which the distance 
exceeds the width. Assembled by these empiric indices the clubs of 
this group fall into the array shown in table 50. 
These complete such notes as are needed in the record of the clubs 
whose origin is distinctly from the wood employed. We next proceed 
to the consideration of the club types in which the form and struc- 
tural detail of the head and parts thereto adjacent are insusceptible of 
comprehension as timber products. |
