"Very well indeed," responds the operator at Portland; "much better than when the batteries were on; the current is steadier and more reliable. Suppose we continue to work so until the aurora subsides?" "Agreed," replied the Boston operator. "Are you ready for business?" "Yes; go ahead," was the answer. The Boston operator then commenced sending private dispatches, which he was able to do much more satisfactorily than when the batteries were on, although, of course, not so well as he could have done with his own batteries without celestial assistance. The line was worked in this manner more than two hours, when, the aurora having subsided, the batteries were resumed. While this remarkable phenomenon was taking place upon the wires between Boston and Portland, the operator at South Braintree informed me that he was working the wire between that station and Fall River--a distance of about forty miles--with the current from the aurora alone. He continued to do so for some time, the line working comparatively well. Since then I have visited Fall River, and have the following account from the intelligent operator in the railroad office at that place. The office at the station is about half a mile from the regular office in the village. The battery is kept at the latter place, but the operator at the station is provided with a switch by which he can throw the battery off the line and put the wire in connection with the earth at pleasure. The battery at the other terminus of the line is at Boston; but the operator at South Braintree is furnished with a similar switch, which enables him to dispense with its use at pleasure. There are no intermediate batteries; consequently, if the Fall River operator put his end of the wire in connection with the earth, and the South Braintree operator do the same, the line is without battery, and of course without an electrical current. Such was the state of the line on the 2d of September last, when for more than an hour they held communication over the wire with the aid of the celestial batteries alone. This seems almost too wonderful for belief, and yet the proof is incontestable. However, the fact being established that the currents from the aurora borealis do have a direct effect upon the telegraph-wires, and that the currents are of both kinds, positive and negative,--as I have shown in my remarks upon the aurora of 1852, which sometimes left a dark line upon the prepared paper, and at other times bleached it,--it is a natural consequence that the wires should work better without batteries than with them, whenever a current from the aurora has sufficient intensity to neutralize the current from the batteries.
