A Timber Preservative.

Remarkable success is said to have been attained with a new process for preserving timber lately introduced in England. The agent employed is melted naphthaline, contained in a tank, in which the timber is immersed. The temperature of the bath is about 200 deg. Fahrenheit or a little below, and is evenly maintained, the heat being derived from steam pipes, passing through the tank. The timber is soaked from two to twelve hours, according to the size of the piece. It is believed that wood which is thus thoroughly impregnated with naphthaline, which takes the place of the sap and water it expels, will have peculiar advantages in its susceptibility to polish, for which merely rubbing with a cloth will be sufficient
