resembled those in the Wauneta and those in the cylinders of 
Holdrege and Hastings soil were very similar. The plants in Lin- 
coln soil were in very bad condition, appearing to be seriously 
suffering from drouth. During the next month none of the plants 
made any progress and all were injured during the first week of 
June with its continued high temperature. The general conditions 
on May 27 may be seen from figure 21. None of the plants had 
died since those recorded on April 30 but many were dying by 
June 9. 
The plants in the H O cylinder were all dead on June 17; only 
one spike had formed and that bore no grain. On June 26 the 
plants in the Holdrege cylinder were dead, having formed only 
one spike and this being barren. On the next day the plants in 
the Lincoln cylinder were all dead. The extremely unfavorable 
weather during the last week of June and the early part of July 
caused the remaining plants to die rapidly, all being dead by 
July 18. A single spike — on a plant in the Wauneta cylinder — 
formed grain. Additional data on these wheat plants are given 
in Table 21.
