Important Discovery.--We are informed by two gentlemen who lately passed through Syracuse, N.Y., that Mr. Avery, the proprietor of an extensive iron foundry in that place, has made a very important discovery in relation to casting of iron. The best kind of earth used in foundries is brought we believe from Canada. Mr. Avery analyzed this earth, and found it to contain a certain portion of blue clay. Following this up by a series of experiments, he discovered that if common fine sand was mixed with common blue clay, in the proportion of one tenth part of clay to nine tenths of sand, it would constitute the best possible composition for casting that he had every used. Even the most delicate castings came out perfectly free of sand, and required no sort of cleaning by vitriol. He dismissed ten of his cleaners on the spot, and estimates that his composition will make an immense saving in the expense of iron foundries--in the diminution of labour, the cheapness of the sand, and in the disuse of vitriol in the process of cleansing, We hope that our neighbours of the furnaces will immediately test it by experiment.
