THE BATTERY ROOM.
Here, too, we see great improvements in the telegraph art. The battery tables are made of strips of plank set edgewise in tiers like a flower stand, from these strips rise pins or standards, upon the tops of which are placed a small glass insulator, and upon this is placed a wooden cap of the size of the battery tumbler, to be supported by it. This arrangement prevents the possibility of any local connection between the cups or cells by moisture or contact. Two batteries supply the electric fluid for the whole number of wires which pass from this office connecting with all points where telegraphic communication is established.
After a series of experiments with numerous so-called improved batteries, the company have gone back to the regular Grove battery which has been in use ever since the introduction of the magnetic telegraph, as giving the most steady, reliable, and powerful current. Some minor improvements have been made in the form of the . . . [illegible text] . . . and porous caps, but the battery is strictly "Grove." For local batteries the "Daniels" somewhat modified and improved is used.
