1 Percentage of stand determined from an actual count of the plants in each row. 
2 Lint very short. 
3 Lint but little better than Triumph. 
As is shown, the Vergatus gave the highest yield, but the lint was 
very short, making it an undesirable variety. 
GRAIN SORGHUMS. 
The experiments in grain sorghums reported on last year? were 
continued. Both variety and time-of-planting tests were made. 
Table V gives the average yields of the varieties for three plantings.
