counties, but for the State the yield will be considerably below the 
average. The quality, however, was good, notwithstanding the fact 
that red rust was becoming quite general at the time harvest began. 
Corn made an abnormally rapid growth and in many fields was up to the 
average condition, but for the State at large the crop is very uneven. 
On low and flat fields, which were previously flooded, corn is decidedly 
below the average in growth, but has good color, is growing rapidly 
and, with continued warm weather and occasional showers, will make a 
fair crop, if frosts do not come before the average date. 
Pastures and potatoes have remained in good condition, but are be- 
ginning to show the effects of dry weather and would be benefited by 
a good rain. The apple crop will be very small.
