DIMENSIONS AND STRUCTURAL DETAILS. QI 
clutch functions in terms of the circumference of the object held. If 
each hand spans one semicircumference of the object, the force of 
the clutch is conditioned by the amount of opposing force which 
the thumb and fingers are capable of exerting along the diameter of 
the piece. When the clutch engages with less than a semicircum- 
ference the clutch is loose; in proportion as it engages with more of the 
other semicircumference it becomes stable and effective. We shall 
expect to observe these conditions in the next tabulation of the clutch 
data, in which for each of the units of circumference we set down in 
table 41 the type of weapon from which the measurements derive.

We derive very scanty information from this tabular conspectus 
of hafts of the several club types. It is at once apparent that the ula 
missile clubs afford us all the smaller measurements up to 3.25 inches. 
A solitary exception is serrated club 2497, which is distinctly single- 
handed, even if not a dance toy. The two units 3.5 and 3.75 carry 
4 larger ula and the undersized pieces of several other types. At 
4 inches with 25 pieces, at 4.5 inches with 25 pieces, at 5 inches with 
18 pieces, and at 5.5 inches with 12 pieces, we seem to find some 
dimensions roughly standardized as stock patterns. Bearing in mind 
the constancy of 7 as meaning that even an inch of increment in girth 
results from only an addition of one-third of an inch in diameter, we 
feel justified in assembling other units about these decisive points 
from the half inch next preceding to include the quarter inch next
