Superintendents, Master Mechanics and Engineers of many prominent Railway Companies, who have tested the Paterat Tallow E"a clicing for Car Journals, have expressed to me in writing, surprise and satisfaction at its performance, and many of them pronounce it superior to any article heretofore introduced to them for Lubricating Purposes, and as a RELIABLE PREVENTIVE OF HOT AXLES.

[ocr errors][subsumed][merged small]

It eaccludes dust from the journal. It causes the brasses to wear level. It can be used in any kind of boares. It cannot be spilled out. It is not affected by difference of climate. It lubricates more thoroughly. It requires very little labor and attention. It is considerably cheaper than any other good lubricating material The TALLOW LUBRICATOR for Marine and Stationary Engines, and MACHINE OIL, possess advantages over every other similar compound. I wish to secure patronage mainly upon the merits of my materials, therefore, do not here present copies of the many testimonials to be seen at my office from parties who have extensively tested and used the same. My request is “BE. YoUR own JUDGE.”

TEMPERING GRAWERS AND DRILLS.

A watchmaker in Gosling, by the name of Schussleder, has recently published his method of hardening gravers and drills, which he claims renders them almost as hard as the diamond. He first heats the tool to a white heat, and then presses it into a stick of sealing wax, leaves it but a second there, and then sticks it into the Wax in another place. This operation is rapidly repeated, until the graver is too cool to enter the wax. Drills tempered in this manner will pierce the hardest steel tem; pered in the usual manner. In turning or drilling, the tool is moistened with oil of turpentine. .
