A New Signal Lamp for Vessels. - We yesterday had the pleasure of examining the new Signal Lamp for vessels invented by Mr. J.R. Pierce of this city, for which application for a patent is now pending before the Department in Washington.

The lamp examined by us is designed for the Minnehaha, the new start vessel just launched from the ship-yard of James A. Baker, of this city. We also had an opportunity of comparing this lamp with others now in use, and any person, whether acquainted with marine matters or not, will at once perceive the vast superiority of the new lamp.

Its mode of operation is entirely different; the white, red and green lights can be shifted in an instant; and it is so arranged that it gives both a head and side light, an important improvement over the old lamp. Another improvement is a chimney which slides up and down with the light through the different colors of glass, at all times carrying away the smoke.

Mr. Pierce's lamp is convenient, portable, never liable to get smoked, easily cleaned, and in case of accidentally breaking a glass, is so arranged that it can be repaired on board the vessel without taking it to the manufactory, by simply keeping a few plates of glass and slipping them in as required.

A large number of Lake Captains have examined this new invention and all concur in the opinion that it is the lamp required for marine service. It is highly creditable to the mechanical skill of Mr. Pierce and must come into general use.
