This year, lilac on the 11th, willos on the 30th. Poplars were flowering 

 here on the 30th of last month ... The first swallows were seen here 

 on the l*fth of March. (Last year I did not pay any attention to the 

 latter). 



Thank you for your reply concerning the yearly barometer readings. 

 I asked this question since I thought I noticed in some collections of 



meteorological tables a certain , namely at the beginning of the 



decade a maximum, then a gradual lowering of the yearly average until 

 the *fth, 5th and £th year and then again an incline until the end. This 

 would be a period of ten years. 



With regard to your question whether the northern lights have any 

 influence on the climate, I have found several references which confirm 

 my assumption.-- You may remember that I mentioned to you in St. Louis 

 that there might be some truth to the popular belief that the northern 

 lights are an indication that the weather would turn colder. My observations 

 here have confirmed this, 9 f ten in a very peculiar manner, andin Prof. 

 Carwell's tables, I find that in at least 120-130 cases out of l?0 f a 

 colder temperature followed the appearance of the polar lights. It might 

 be interesting to make a comparison of observations and to try to find 

 out about the same effects in other localities in order to prove, for 

 instance, that in America, a cold wave spreads simultaneously over large 

 partw of the country or not. 



I wrote to Prof. Henry about this and am waiting for his reply. 

 Several circumstances made me bother him with this question and I hope 

 to receive a satisfactory answer. 



With best regards, I remain, 



Your obedient servant, 

 Ad # F. Bandelier, jr.
