_ 3. GoZdfnj4rZ:awsrts, (from iheN, O.Bee.) — Some weeks ago we men- 

 tioned the fact that Mr. Snell, an accomplished mineralogist of our city, 

 had discovered, in the course of scientific exploration in certain portions 

 or Arkansas, unmistakeable indications of an auriferous deposit. Mr. S. 

 had in one instance picked out of the crevice of a rock a piece weigh- 

 ing about an ounce, in which gold was abundantly intermixed with the 

 quartz, in the usual mechanical combination in which the two are found. 

 Although this was but an isolated discovery, Mr. Snell predicted, with 

 a confidence based upon the geological peculiarity of the country, that 

 gold existed there probably in sufficient quantities to remunerate labor 

 and enterprise. His prediction has been speedily verified. 



Yesterday we had the pleasure of examining three very handsome 

 specimens of Arkansas gold, as genuine as any that ever glittered 

 amidst the sands of California. They were found in the bed of White 

 I'iver, some miles above Batesville, and in a range of rocky country, 

 precisely similar in feature to the region where Mr. SnelJ obtained his 

 specimen. The largest lump was a mass of quartz of a dirty white 

 color, profusely penetrated by the precious metal, and in some places 

 so completely mingled with it, that the gold seemed like an integral 

 P^rt of the rock. The other samples were smaller, and presented 

 nearly a similar appearance. We presume that in the three pieces 

 Jhere could hardly have been less than five or six ounces of pure gold, 

 ^hese products of the mineral wealth of Arkansas were sent to Mr* 

 ^nell to be assayed. 



4. RUt and Fall of Lake Erie, (from the Buffalo Advertiser of 

 April 16.) — Various papers have recently alluded to the rise and fall 

 ^^^ Lake Erie, maintaining that It is periodical every few years. The 

 ^^ ■ " "our intelligent citizens, who 



since 1839, settles the matter 

 ^ost conclusively. 



The Toledo Blade represents Lake Erie as falling, and that there is 

 a periodical rise and fall of its surface, once in twelve or fourteen years. 



Some of your readers may be pleased to get facts from authentic 

 records.
