ton, Davenport & Muscatine Railwaj', and interurban communication with 

 Muscatine was suspended during the entire day. At Muscatine the damage 

 to bridges, roadways, basements, stocks of goods, houses and household 

 goods is placed at $200,000. 



Corn matured and dried rapidly till the rains set in, and about 85 per 

 cent was safe from frost at the close of the month. Silo filling and fodder 

 cutting progressed rapidly. The hard, dry condition of the soil made plow- 

 ing almost impossible till the 17th. Then the rains came gently, steadily 

 and copiously for the next three or four days, saturating the soil to a great 

 depth. Plowing and winter wheat seeding were pushed rapidly 22d-27th. 

 It is probable that the winter wheat acreage will be reduced to a pre-war 

 basis or about one-third that seeded in the fall of 1918. Pastures recovered 

 from the drouth rapidly. Live stock, which has been fed, began to subsist 

 on pastures toward the end of the month. Stock water and wells which 

 had failed in many places in the south part of the State were replenished. 

 The rains came too late for potatoes which are a poor crop, generally. Many 

 farms have not raised enough for their own use. 



Pressure. The mean pressure (reduced to sea level) for the State was 

 30.00 inches. The highest recorded was 30.33 inches at Dubuque, on the

 range was 1.00 inch.

 was 33° at Inwood on the 25th. The temperature range for the State 

 was 66°. 



Humidity. The average relative humidity for the State at 7:00 a. m. 

 was 82 per cent and at 7:00 p. m. was 61 per cent. The mean for the month

 highest velocity reported from a regular Weather Bureau Station was at 

 the rate of 45 miles an hour from the south at Sioux City, on the 26th. .
