It will be seen by the above data that no. 6 wheat had an average 

 of a little less than 12 per cent shrunken grain for 16 samples, the 

 average number of maggots to a head for the different samples rang- 

 ing from I to over 15. This average does not include one sample of 

 small heads taken from the field of Carl Hakes and showing over 50 

 per cent of shrunken grain. Subsequently Mr Hakes reported that 

 the field showing 12. i per cent of shrunken grain in the samples 

 secured, yielded 22 bushels an acre, thrasher's measure. He esti- 

 mated that there were 2 bushels of screenings an acre and considered 

 there was some, though not serious, injury by the midge. He adds 

 that the above figures are only approximate and that his early wheat 

 yielded about 35 bushels an acre. It was from this latter that the 

 sample of small heads showing 64 per cent shrunken grain was secured. 



Carl Parker reported yields of 12, 32 and 22 bushels an acre from 

 three fields showing in samples 25.7, 5.2 and 20.1 pier cent of shrunken 

 grain. He considered that the wheat was seriously injured by the 

 midge and estimated the loss at 20 per cent.
