PAG. 55. NOTE X. We hâve in a little essay, „On the method of Providing against. 

 Summer Night Frosts by the Use of Torches", stated the time during summer when frosts 

 generally occur, and these forecasts are fairly certain, but may vary to within 3 or 4 days 

 earlier or låter. These times are the following: The beginning of June, Midsummer-time, 

 July 10:th, July 22:nd, August 25:th and the beginning of September. Thus, the great frosts 

 of 1867 and 1892 happened on the 4:th of September and the 31:st of August, not to men- 

 tion several other instances. The point of time, will, however, be somewhat différent in dif- 

 férent parts of the country. 



PAG. 56. NOEE XI. Expenments, executed the autumn 1892 at Kronoby Agricul- 

 ture Institut of Herr Lång, give a god reason to a such expectation.
