These annual abstracts are carefully compiled and 

 published yearly in the Genesee Farmer. 



The monthly mean of each month is found by 

 taking three daily observations ; the first at sunrise, 

 the second about 2 P. M., and the third one hour after 

 sunset ; these are added and divided by 3, which gives 

 the daily mean ; and the daily means at the end of 

 each month are added and the sum divided by the 

 number of days in the month. This process gives 

 the monthly mean temperature. The annual mean is 

 found by adding the daily means at the end of the 

 year and dividing the sum by the number of days in 

 the year. 



The highest degree is the highest point to which 

 the mercury in the thermometer rises during the 

 year ; the lowest, the lowest that it falls within the 

 same period ; and the range is the difference between 

 these extremes. The wind in 1843 blew from the 

 Northwest 126 J days — 26 days more than from the 

 North, Northeast, East, Southeast, and South added 

 together. The wind blew from the Southwest, West, 

 and Northwest 256 days. This shows how greatly 

 the westerly winds prevail over the easterly, over the 

 locality where these observations are made. 



The day is registered fair or cloudy according to 

 the prevailing state of the atmosphere during each 

 half day. However slight the sprinkle of rain, the 

 day ia set down as one on which rain fell, and so of 

 snow. The snow is caught in a vessel during the 



snow season and melted, and then gauged: this 

 added to the falls of rain, which are gauged, gives 

 the total fall of water for the year in inches. 



The greatest fall of water for any one month 

 during the year 1848 was 6.16 inches — this was 

 July : the least fall was in April — 78 hundredths 

 of an inch ; the warmest month, August : the cold- 

 est, February. The highest annual mean tem- 

 perature of the last 14 years, 48.66 degrees— this 

 was 1846: the lowest of the same period 43.71 

 degrees — making a range of 4.95 degrees. The 

 highest degree of the thermometer, kept in the shade 

 where there was a free circulation of air, and not 

 exposed to reflected heat, within the above named 

 period, 102 degrees — July 16th, 1845 ; and the lowest 

 8 below zero — -February, 1836 ; making the greatest 

 range of the thermometer 110 degrees. The greatest 

 annual fall of water in 1847, 39.99 inches ; and the 

 least fall, 25.46 in. The annual average is near 35 

 inches. The greatest fall of water for any month 

 within the above period, 6.79 — October, 1846 : and 

 the least in January, 1837 — 16-hundredths of an inch. 



The year 1848 has few predecessors more marked 

 for political changes ; and these are not confined to 

 the eastern continent' alone, though much greater and 

 more exciting there than here. It is memorable for 

 the progress of the Cholera on the eastern continent, 

 and also for its appearance in New York and New 

 Orleans on the western just before its close. It was 

 a year also which the husbandman will have as little 

 cause to forget as the lover of liberty ; for it crowned 

 his toils and cares with abundant harvests.

Jan. 12, 1849, shows the lowest fall of the mercury, here, 

 on record. 



The coldest day within the above period, was Fri- 

 day, Feb.. 16, 1849 — the mean temperature of the day, 

 from three observations, being 2§° above zero. The 

 record of the 16th of Jan., 1840, shows 3 deg. above 

 zero, I of a deg. higher than the cold Friday of 1849. 



Note.— Saturday morning, Feb. 17; the mercury 

 7 deg. below zero at 7 o'clock A. M.; at 7J, 5 below; 

 and at 8i, zero. This an hour and a half after sun- 

 rise, and a clear atmosphere. 



The Feeding of Animals should be regulated 

 by a variety of considerations. The young who 

 may be destined for maturity, should be supplied 

 with milk from the dam until weaning-time. No 

 food can be substituted for the well-filled udder of 

 the parent, which is so safe, healthful and nutritious.
