The results are somewhat different from those expected when 
the experiment was planned. They are to be explained by the fact- 
that the unusually heavy rains of the season were almost enough 
to raise beets in that locality without any irrigation. The one irri- 
gation gave the beets all the w iter they needed and the other three- 
irrigations were a positive detriment. 
In connection with the tests of seed from different sources, Mr. 
C. K. McHarg, of Pueblo, made for us some tests in regard to late 
irrigation. 
All of the plot, containing three-fourths of an acre, was treated 
alike until the latter part of the season, then one-half received no 
further irrigation, while the other half was given two irrigations 
additional. 
The crop was weighed for each variety separately and yielded 
the following results :

In this case there was a gain of one-seventh in the weight of 
the crop by irrigations late in the season. 
An average sample of the Original Kleinwanzlebener from the 
part receiving the extra irrigations tested 16.42 sugar in beet and 
81.0 purity, while a sample from the other half tested 15.79 sugar 
and 81.7 purity. Here there was an advantage in both quantity 
and oualitv from the late irrigation.
