 account for the casting up of this wreck.

2. " The Results of the Destruction of Forests upon the Biver Wolga at 

 Astracan," by Dr. A. Wojeikof, of St. Petersburgh. 



(abstract.) 

 The author states that nowhere in the old world is the influence of man on 

 the physical configuration better seen than in Russia, as there some of the 

 operations long ago effected in Westei-n Europe (such as the cleai'ing of forests 

 and the cultivation of the land) are of recent date, and we can examine if the 

 change of climate caused by the destruction of forests is as great as it is stated to 

 be. The observations on the Wolga, made at the hai-bours of Astracan, furnish 

 us with some means of doing so. With this view four ten-year periods are com- 

 pared, as otherwise the anomalies of single years would be too conspicuous.
