Such ratios, with the mean internode lengths of July taken as 
100, are: 
Internode No 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 
Ratio 100: 137 129 111 92 71 59 51 48 48 48 48 50 51 52 52 
The mean internode length of Snowflake is, then, approximately 
50 per cent of that of July, if internode length be determined at 
the end of any internode from the seventh to the fifteenth. 
Obviously a comparison between these races in respect to inter- 
node length is unreliable if internode length is determined at the 
end of any internode before the seventh. But, if either of them is 
to be compared at all with any bush bean, the comparison must 
relate to the first five or six internodes. 
The illustration used above is an extreme one. The difficulty 
in comparing pole and bush beans is not generally so great. Other 
examples will make this plain. It has been shown above that 
Snowflake is a small pole bean with a mean internode length of 
about 50 per cent that of the tall pole bean, July. Triumph is a 
very short bush bean and Red Marrow a rather tall one. Let us 
compare the mean internode lengths of 79 plants of Triumph and 
73 plants of Red Marrow with those of Snowflake and July as 
given above. The comparisons to the end of the fifth internode 
are:

From the comparison with Snowflake, it might at first seem 
that the internode length of Triumph is about one-half of that of 
Snowflake and the internode length of Red Marrow nearly equal
