per cent. ; but Lis mill was an imperfect one. Under favorable 

 circumstances as much as seventy per cent, might be calculated upon, 

 and of this, seventeen per cent., was crystallized sugar. The quan- 

 tity of sugar per acre he estimated at three thousand pounds, but 

 both quantity and quality would be controlled by the perfection or 

 imperfection of processes of manufacture. Mr. Wray had discov- 

 ered the only successful method of obtaining the sugar which has 

 been made public. M. de Montigny, Count de Beauregard and 

 others, had sought in vain for it, but he had been fortunate enough 

 to arrive at a complete success, as was proved by the samples of su- 

 gar which he exhibited to the Club. 



Several specimens were shown. One of them is not purged of the 

 molasses, because Mr. Wray desired to prove that the syrup from the 

 Imphee possesses no unpleasant flavor. We tasted it, and found it 

 very pleasant in flavor, reminding one of maple sugar. Another 

 sample had been purged ; it presented the appearance of fine clayed 

 Havana. The crystals are firm and sharp, and the taste is not diflfer- 

 ent from good Havanas, which are now selling in the New York 

 market at 11 and 12 cents, by the quantity. 



If Mr. Wray is not amiss in his calculation as to the yield per 

 acre, or if we can obtain but one thousand pounds, what an im- 

 mense gift to American agriculture is he about to make ? Our rap- 

 idly waning crop of sugar is at once exchanged for the greatest 

 abundance, and a vast source of wealth is opened for our farmers. 

 He has already expended some twenty thousand dollars in his ex- 

 periments and attempts to introduce it into Europe, and it is to be 

 hoped that his visit to our country may prove remunerative in propor- 

 tion to the importance of his discovery to ourselves.

AN EXPLANATION— GEOLOGY OF OHIO. 



It was announced, more than a twelve-month since, that a work on 

 the Geology of Ohio, would be published by the undersigned, in 

 connection with Dr. John Locke, of Cincinnati. It was planned 

 so as to embrace, more particularly, the Geology of the districts 

 traversed by Rail Eoads. But the death of that distinguished phi-
