obtained from most varieties. This was due to a considerable extent 
to their location on a part of the farm exposed to the ravages of 
sparrows, by which much of the seed was destroyed. In 1908, a 
good year, their yields compared well with those of the other varieties. 
On the whole, however, their performance has been disappointing. 
COMPARATIVE YIELDS OF THE MILOS AND DURRAS. 
Table XVIII compares the annual and average yields of the leading 
varieties of the milo-durra group. The data cover 5 milos, 5 Dwarf 
milos, 1 lot each of Alba (White) milo, feterita, and White durra, and 
6 durra-kafir hybrids, a total of 19 lots. Of these, 13 have been 
grown during all years and 6 during only the last seven years. 
Among the six subgroups, Dwarf milo is seen to lead, with average 
acre yields of 26 or 27 bushels. The Standard milos and Alba milo 
and feterita come next, with acre yields varying from 20 to 23 bushels, 
in round numbers. Below them rank the White durra and durra- 
kafir hybrids. As noted previously, the average yields of the last 
named probably would have been higher if they had not been seriously ' 
attacked by sparrows in 1915, the year ot very high crop yields.
