exception already noted, while the percentage of pods of 6 inches and 
shorter in group 4 was less than that of the corresponding length in 
group 6 in every instance. 
These measurements show the importance of limiting the crop if a 
large proportion of long pods is to be had, as the number of pods 
produced has a direct and most pronounced effect on length of pods.

In the table below, which shows the weight of cured pods of different 
lengths, it is seen that one 8-inch pod weighs more than two 6-inch 
pods or three 5-inch pods. Longer pods are also worth intrinsically 
more than an equal weight of shorter pods, since, in addition to making 
a better appearance and bringing a higher price per pound, they 
produce an extract which, though not markedly different, is slightly 
superior to that from the shorter pods. 1 The number per pound was
