continued to be a pes fr / of sons importance to horses and cattle 
in the escarpment from the plateau region of western Texas, and 
they also extended their area of damage to the plateau region 
and to some extent in the lower lands along the rivers. The 
occurrence of anthrax in a number of herds has been attributed 
to the horse flies

L„ Haseman (isagust 27)x This pest has been less abundant than 
during the month of Jul.7 though many stockmen have called for a 
formula for preparing a homemade fly spray,, 
F* C, Bishopp (August 27); During the period July IS to August 
15 a very severe outbreak of the stable fly occurred throughout 
the grain belt of nor thern Tefas and southern Oklahoma* In the 
opinion of many dairyraen 3 stockmen, and farmers, the outbreak 
was more severe this year than at any tine since the unprecedented 
condition which occurred in 1912. During the height of the 
outbreak dairymen experienced a reduction of from 5 ^o oO per 
cent in milk flow. Gone threshing gongs discontinued operation be- 
cause of their inability to keep teams hauling in the fields. 
Cattle on feed began to lose weight and were rushed to market, and 
there was a general lowered condition of all livestock in the 
heavily infested area. Reports of the death due to the flies 
either directly cr indirectly through accidents were not uncommon, 
and included sheep* cattle, and horses. 
The condition tvhioh gave rise to the outbreak of this sumnsr 
were similar to those which prevailed in previous outbreaks , i*e„ , 
a large grain crop with the production of a great deal of straw 
and the occurrence of an abnormal amount of rain during threshing 
which not enly produced favorable breading places in straw stacks, 
but resulted in the fermentation of grain in the shock and the 
breeding of i ; lerein, 
luring the last week there has been a marked subsidence in the 
number of flics.-, although they are still sufficiently abundant to 
causa severe annoyance^
