REMARKS. 



The most noticeable features of the weather for September were 

 the heavy rainfall on the 14th and 15th and the frosts on the 2 2d 

 and 23d. The rainstorm was one of the most severe that has oc- 

 curred at this station since it was established. Starting on the even- 

 ing of the 13th with only a trace of rain, and continuing the next 

 morning with only a light drizzle, the storm did not become heavy 

 until well along in the afternoon of the 14th, and up to 8 p. m. the 

 total precipitation was .70 inches. From 8 p. m. until 7 a. m. on the 

 15th the downfall at times was extremely heavy, and the capacity of 

 the rain gauge was exceeded. The lightning from 10 p. m. until mid- 

 night of the 14th was almost incessant. The storm ceased at about 

 9 A. M. on the 15th, and the total preciiDitation, as determined by 

 measurement of the depth in receptacles near the Dining Hall, was 

 found to be 4.10 inches. 



The first frost of the season occurred on the morning of the 

 2 2d, and proved to be unusually severe. Tender plants were killed 

 and much damage done. On the morning of the 23d another heavy 

 frost was noted and the thermometer fell to 26 degrees, making a 

 new low record for September at this station. 



The barometer was generally high until near the close of the 

 month, and the minimum for the month occurred on the last day. 

 The mean pressure for the month was considerably above the nor- 

 mal, and the range was nearly 50 per cent more than usual. 



The mean temperature was between one and two degrees below 

 the normal, and the range was large, owing to the low minimum 

 record. 



The total precipitation was about a third more than usual, and 

 the amount of cloudiness slightly more than normal.
