AGRICULTURAL REPORT. 



A clouded sky at the above-named places may in a measure account for the 

 lower temperature for the summer months as observed in the shade, and 

 strengthen the credibility of the results of the observations of Dr. Daubeny, 

 who appears to have proved that the ripening of fruits depends more on the 

 illuminuting rays than on the caloritic and chemical rays of the Bun. 



A table illustrating the temperatures required for the production of wine oj good 

 and excellent quality at certain celebrated localities in Europe.

In the plains near the Baltic, in northern Germany, a wine is produced which 

 is very acid and scarcely potable. The summer mean between Gl° and 64.5° 

 Fahrenheit, being too low, and even the temperature of the hottest mouth 

 falling below the limit of 66.2° Fahrenheit, 



The mean summer temperature of "Wiirzburg, in Franconia, is 65.7°, but one 

 degree above that of Berlin, Avhile its hottest month cannot be more than two 

 degrees higher than the hottest in the latter district ; and when the different 

 qualities of the wines produced in Franconia, and in the countries around the 

 Baltic, are compared with the mean summer and autumn temperatures, re- 

 spectively, we are almost surprised to find a difference of only about two 

 degrees. 



While the wines of Berlin are very inferior, and indeed unworthy of the 

 name, those of Fi-ancouia, whose chief city is Wiirzburg, are held in high 

 esteem. The Leistenwein, one of the kinds here produced, is esteemed with 

 justice the second finest wine of the south of Germany, and the whole produce 

 of the small space on Avhich it is grown is secured for the table of the King of 

 Bavaria, and is scarcely known, and can seldom be purchased. Doubtless 

 there are local influences affecting the quality of the product, or which elevate 

 the temperature above that of the surrounding region and assimilate it more 

 closely to more southern districts, where wines stronger in alcohol are made. 

 It is, however, acknowledged that the choicest variety of grape is grown, and 

 the utmost care exercised in the selection of the most perfect berries, and that 

 it is only by managing both the culture of the vine and the manufacture of ita
