Dear Sir, 



It was not only forget fulnuss or negligence which kept me from 



answering your letter but the death of a member of ray family caused 



some disturbance and only now that things have quietened down, I can 



go back to my duties. 



I am giving you herewith the average of my Meteorological 



observations during the month of March. 



Thermometer . 7 a.m. 37.3 2 p.m. 46.8 9 p.m. 41.9. Average :4l. 9 

 Maximum on the 29th 72° Minimum on the 6th 18.8 



Cloudiness. 6.9. Wind . NW & . Strength 2.6. 

 Rain . 2.89 Snow 1/2" Thunderstorms . 5. 

 Barometer . 29.397 29.374 29.386. average 29.390 



Maximum on the 31st 29.610 Minimum on the 19th 29.118 



Evaporation . 1.7 4.1 2.5 Average: 2.8 



Humidity relation . 85.5 72.7 8l.O Average: 79.7 





I was not sble to make the observations concerning the sun-up regularly 

 until the beginning of this month. Last month, the frequent night watches 



at the bed of a dear sick person caused me to sleep later in the mornings, 

 preventing me from making these observations regularly* 



Between the month of March of this year and the one in l86l I find the 

 following differences: 



The average temperature in March 1961. 1° F # warmer. 



that is, the temperature was the same at two o f clock on the 1st of September, 

 but at 9 o'clock 1 degree warmer in March I96I than in l862 # 

 In March l86l k flinches more rain & 3 A more snow. Barometer in l86l on 

 the average 0.105, higher than in 1862. Maximum: 0.091. Minimum: 0.13^ higher 

 than in 1862. In general everything was earlier than this year. Lilac showed 

 its first leaves last year on the third, willows on the fourth of March.
