wood iuto charcoal. Mr. Rodriguez placed before our committee 

 at the 23d Annual Fair, evidence of a very satisfactory charac- 

 ter, that at New Orleans and Cincinnati, ovens built upon this 

 principle were in successful operation, converting from fifteen to 

 twenty barrels of flour per day each into bread of singular uni- 

 formity and excellence, as far the baking was concerned. The 

 coke or charcoal resulting from the process, sells in the markets 

 for more than the cost of the material used in producing the 

 necessary heat. 



Bread baked for our navy and commercial marine, as well as 

 the bread for ordinary use, in our commercial cities and along the 

 sea board, amounts annually to an immense sum. The portion 

 of its cost which arises from the consumption of fuel, we are 

 unable at the present time to state. It is certainly no inconsid- 

 erable item. By the process of Mr. Rodriguez this portion of 

 the cost of bread, it seems, may be entirely saved. A. C. 



COPPER AND IRON IN COMBINATION. 



Mr. E. G. Pomroy, of Covington, Kentucky, presented at the 

 rooms of the Institute, in August last, specimens of iron and 

 copper, apparently in perfect combination. Mr. P. asserts that 

 it is capable of being rolled into sheets of any desirable thick- 

 ness, drawn into wire, or made into bolts, presenting in all cases 

 the appearance of entire copper, and as he believes, may be used 

 for any of the purposes of copper with advantage, as it can be 

 afforded at 50 per cent less in cost. We have no knowledge of 

 any application of the metals thus combined. Its appearance 

 was favorable, and under the operation of the hammer it sustain- 

 ed in appearance the character it was alleged to possess. A. C. 



SUPERIOR UPLAND COTTON. 



J. V. Jones, Esq., of Burke county, Georgia, exhibited at our 

 23d Annual Fair a bale of very superior upland cotton, which 

 for length of staple, silkiness, and purity of color, claimed par-
