grain and an average of 7 maggots toa head. The owner reported 
a yield of 264 bushels an acre and 13 bushels of screenings. He esti- 
mated the loss due to midge at 5 per cent. 
Leap’s prolific showed a little less than 4 per cent shrunken grain 
in one field and the number of maggots to a head was less than one. 
A sample of St Louis prize had 10.5 per cent shrunken grain and 
an average of 2.5 maggots to a head. 
One field of no. 8 wheat had 28 per cent shrunken grain and an 
average of 18 maggots toa head. The yield was 183 bushels an acre, 
from the machine by weight. There is very little question but that 
the large shrinkage was due to the exceptionally heavy midge infesta- 
tion. The insect was unusually prevalent in that section and there 
were probably heavy losses as a consequence. 
The above figures give some idea regarding liability of different 
varieties to injury by the maggot, though more conclusive evidence 
may be secured when two varieties are grown under practically 
identical conditions or even intermixed, for example, Klondike and 
Dawson’s golden chaff, grown in the town of Le Roy, had 13.8 
per cent and 5.8 per cent respectively in adjacent fields separated 
only by a lane, while the average number of maggots to a head were 
3 and 2 respectively. Again, iron clad and no. 6, grown in Newfane, 
the latter intermixed, had a little less than 4 and 5.1 per cent respec- 
tively of shrunken grain, the former with an average of a little more 
than 1 maggot to a head and the latter with an average of less than 
2 maggots to a head. Finally, no. 6 and white chaff intermixed in 
a Le Roy field had 2.4 and 6.3 per cent respectively of shrunken 
grain and an average of less than 1 and 9 maggots to a head for the 
two varieties. This latter was exceptional and may have been due 
to the white chaff in this particular instance being in a more attrac- 
tive condition at the time the midges deposited their eggs, since 
for the region as a whole, the white chaff was certainly less affected 
by the midge than no. 6. 
Wheat Midge in Rye 
There was a very general and in some cases excessive infestation of 
rye by wheat midge. Conditions in Albany county were brought 
to our attention June 11th by H. E. Crouch, manager of the local 
county farm bureau. He stated that there was a somewhat general 
infestation, some 25 per cent of the heads being affected in portions 
of fields and that the infestation for the county might possibly 
be 1 or 2 percent. It was by no means difficult to find ten maggots 
in one head and the presence of four or five was very common.
