Brooks Patent Insulators.

WE have sometimes been accused of overrating the merits of the BROOKS Insulator, and it has been insinuated in certain quarters, even, that we were actuated by interested motives in so persistently urging their adoption in preference, and as vastly superior to glass and other insulators for telegraphic purposes.

The following testimonial, presented recently to Mr. DAVID BROOKS, by telegraph superintendents, managers and operators, in Pennsylvania, who have had ample experience in working lines insulated with glass and with the patent insulators of Mr. BROOKS, fully sustains all that we have claimed for the latter. As to the second accusation, it is only necessary for us to say that we have no more interest in the paraffin insulators than in any other. In our columns will be found advertisements respectively, it matters nothing to us pecuniary which are purchased and used.

If any person can produce a better insulator that the one presented by Mr. BROOKS, its merits shall be cheerfully and promptly recognized in the only independent telegraph journal in this country - THE TELEGRAPHER.

July 1, 1871,

We, the undersigned, from our own experience, believe as much can be done in wet weather on one wire, insulated with the Brooks Insulator, as on four insulated with the common glass, and at less than one fourth the expense.
