anufacture (whichis by the dry press method) requiring considerable ingenuity. The Syracuse pottery company on i!^. Salina street, producesstoneware. Victor. Close to the I^ew York Central railroad station is thefactory of F. Locke, manufacturer of porcelain electric supplies.Mr Lockes products are made from a mixture of clays, obtainedin part from New York state and in part from other states. Thebody is vitrified, and well fiitted for the insulation of high currents.It is either white or colored. In some cases the ware is glazed witha Quaternary clay that is obtained in the vicinity of Victor. Amongthe large pieces of work turned out by this factory is a series of600,000 insulators for a 40 mile line in California. Rochester. The Flower city pottery. StonewareUtica.

a 3 o I CLAYS OF Is^EW YOKK 825 SHALES OF NEW YOEK Tliese form an enormous series of deposits in the soutliem regionof the state, as well as some of the central portions. The origin of shale has already been mentioned (p. 502). Fromthe fa.ct that they were deposited in the sea thev are nsnally muchmore extensive than the Quaternary clays immediately underhdngthe surface. The shales found in Ise^v York state are in every case quiteimpure, and often silicious, indeed are at times interbedded withthin layers of sandstone. Owing to their consolidated nature theshales have to be first ground in order to develop their plasticity;the finer the grinding the more plastic the mass. It has also beenfound that in some cases the finer grinding of the shale produces avitrified brick at a temperature that formerly did not allow this,the brick made from the coarser shale showing 6^-7^ absorption. Shales exhibit a great variation in hardness; this fact shows itselfspecially during the grinding process
