ever been known to be discarded, and generally they have 

 been highly approved. Still, as the opinion has prevailed 

 that nothing but French burr would make good wheat 

 flour, this invaluable quarry has laid almost idle and 

 worthless up to the past year or two. The quantity is 

 inexhaustible. It is generally near the surface, but the 

 ground is considerably broken by creeks and ravines, and 

 the veins of grit are from six to twenty feet thick. There 

 are excellent sites for mills, where the power of water 

 might be used for shaping the blocks, with machinery 

 lately invented for cutting stone. 



The face of the blocks, when dressed, shows a surface 

 quite as open as French burr, free from all loose pebbles, 

 sand, iron nodules, and veins. In fact, the cavities when 

 examined with a powerful magnifying glass, appear as 

 though they were coated with an enamel of pure quartz, 

 and present an immense number of fine, sharp-cutting 

 edges. Years of exposure to the atmosphere present no 

 appearance of change, and I am assured that the blocks 

 stand fire perfectly, and that there is no difficulty in 

 selecting them so as to form the whole stone of exactly 

 the same quality and of equal goodness throughout the 

 whole thickness. 



The present price of millstones is about the same as 

 French burr, but the great abundance of material and 

 the constant increasing demand, will enable the company 

 to supply stones or blocks at a price so much below those 

 imported, that every American farmer has a direct inter- 

 est in this American quarry. So far as my own opinion 

 is worth in promotion of this new branch of home pro- 

 duction, I give it most freely in favor of the Georgia burr 

 over any other in the world. I saw many letters from 

 millers to corroborate this opinion. I recommend the 

 proprietors to take immediate measures to introduce these 

 stones into all the northern states. They should establish 

 an agency at once in New- York City,^ not only for the 



'A note to the article announced: "A. B. Allen & Co. are ap- 

 pointed the New York agents for the above millstones, and will be 

 pleased to answer any enquiries regarding them."
