TELEGRAPH WIRES UNDERGROUND.

Philadelphia newspapers report that the American Union Telegraph

Company are about to try in that city the experiment of putting their

wires underground. The plan works well enough in European cities, and

there would seem to be no reason why it should not succeed here, save

the indisposition of the companies to bear the first cost of making the

change. For some months the Western Union Telegraph Company has had the

matter under consideration, but will probably wait until pressed by a

rival company before it undertakes the more serious task of taking down

its forest of poles and sinking the wires which contribute so much to

the prevailing ugliness of our streets. Sooner or later the poles and

wires must come down; and it is altogether probable that the change will

be beneficial to the companies in the long run, owing to the smaller

cost of maintaining a subterranean system. It will certainly be an

advantage to the community.
