REMARKS 



The weather during the month was disappointing in general 

 although it is difficult to say in what respect. It is true 

 that the mean temperature was rather low but it was 

 nearly the same as in 1915 and 1920. It was much warmer than 

 the abnormally cold May of 1917. It was rainy and cloudy but 

 the total rainfall was only about two-thirds of the normal and the 

 hours of sunshine more than usual. No frost of any conse- 

 quence occurred and yet it was bordering on frost three days of 

 the last week of the month and, in fact, frost was noted on the 

 grounds in neighboring places. The seasonal advance was 

 slow and normal conditions at the beginning of the month, 

 changed to a backward condition of about ten days at the close 

 of the month. 



On examining the records we find that the mean barometer 

 was unusually low and although the wind movement was rather 

 large the changes in barometric pressure were not especially 

 marked. The shifting of wind direction was more frequent than 

 usual. 



The temperature record shows a mean hourly temperature 

 about four degrees lower than normal. This lesulted in making 

 it rather uncomfortable without heat in buildings as the normal 

 May temperature is very close to a suitable one for comfort. 



The maximum temperature was thirteen degrees lower than 

 the normal and the minimum nearly three degrees higher than 

 the normal, giving a very small range. The maximum tempera- 

 ture rose above 70 degrees on only seven days of the month, 

 while normally we expect records above 80 degrees several times 

 in May. 



The total precipitation was small and fell during many scattered 

 storms of no severity, excepting that of the 24th, when for a 

 short time there was a very heavy down pour. 



The mean dew-point was rather low and the relative humidity 

 practically normal. 



There was nearly an equal number of clear, fair and cloudy 

 days.
