the same conditions. The shortest period recorded is 93 days, in 

 1914, and the longest 122 days, in 1912, though the total duration in 

 1910, 1915, and 1916 was between 115 and 119 days. In 1910 the 

 vegetative and ripening periods were both prolonged, while in the 

 last two years only the ripening period was extended. The reasons 

 for these facts have been already stated under "Milo" and "Dwarf 

 milo" and need not be repeated here.

The average drill-row space per plant and per stalk in feterita is 

 somewhat longer than in the case of milo. This is due chiefly to the 

 softer seed and consequent poorer germination under unfavorable 

 conditions, such as the dry spring weather in 1910 and the wet 

 weather in 1915. In these two years the plant space was 37.3 and 

 29.8 inches, respectively, the widest spacing recorded for any variety 

 in any year. The closest was 7.9 inches in 1913 and 1916. 



The stalk space has varied only about half as widely, owing to 

 the very free tillering of feterita. It has been more difficult to as- 

 sign the proper limits to the vegetative and fruiting periods of 

 feterita than to those of any of the other commercial varieties. This 

 is due to the more uneven stands obtained and the greater variation 

 in the number and percentage of suckers produced. Under dry 

 spring conditions even a thin stand of feterita may head at an average 

 height of only 3 or 3.5 feet. Under the influence of subsequent 

 rains it may continue to produce suckers for some weeks, and these 

 in turn continue to produce heads and to ripen seed. This condition 

 represents really not one crop but two or three crops in succession
