It will be seen by the above data that no. 6 wheat had an average 
of a little less than i2 per cent shrunken grain for 16 samples, the 
average number of maggots to a head for the different samples rang- 
ing from 1 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 12.1 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 sampies 25.7, 5.2 and 20.1 per cent of shrunken 
grain. He considered that the wheat was seriously injured by the 
midge and estimated the loss at 20 per cent.
