 HTJMBOLDT TO YARNHAGEN. 



BEKLIN, April Uth, 1856. 



I COULD not but speak, being the Nestor of Prussian 

 mining officials, and prone to boast of my calling. My 

 reliance upon your indulgence, dear and worthy friend, is 

 so great, that I am emboldened to send even you a copy 

 of these unimportant lines. Count B. deserved this 

 praise. Free from opinion of any kind, he is useful to 

 the art of mining, and still occupies himself with scien- 

 tific pursuits since he has resigned the direction. 

 With unshaken constancy, yours, 



A. v. HUMBOLDT. 



NOTE BY VABXHAGEN. Enclosed was the address delivered at the 

 fiftieth anniversary of the entrance into the royal miners of his 

 Excellency the Actual Privy Councillor and Captain of Miners, Count 

 Beust. April 9th, 1856.
