A telegram announces sudden illness; death; an accident; prices of gold every five minutes; prices of stocks every hour; sudden fluctuations in the values of commodities; orders rooms at a hotel, while the sender is _en route_ and flying to the distant city as rapidly as steam can carry him; countermands orders and instructions contained in letters sent by post; orders letters to be returned unopened; orders the arrest of fugitives from justice after they have taken their departure on the railway; orders the search for a package left in the cars, and its return by a succeeding train; announces that the Merrimac has destroyed several ships of war, and may get to sea in spite of the Monitor and ravage the coast; announces that the flag has been fired upon at Charleston, and in twenty minutes arouses the entire nation. None of these things are possible for the post. Before a letter could convey the intelligence of the sudden illness, the patient is dead, or convalescent; the dead is buried; gold has changed in price a hundred times; stocks have gone up and down; the man arrives at his hotel twenty-four hours in advance of his letter; the instructions in the letters have been acted upon, and no subsequent ones can repair the damage; the fugitive from justice escapes out of the country; the package left in the cars is irretrievably lost; the Merrimac has been sent to the bottom, and the alarm caused by the tidings through the post, which must continue until another arrival, is groundless; and the flag has been insulted a month, before all the patriots of the country have heard the tidings by the slow, plodding mail. The telegram is often the index to the more full and copious information conveyed by the post, but it does not supersede it. There is no similarity in the conveyance of matter by post or telegraph. A letter deposited in a post-office is placed in a bag, and carried to its destination with no less labor and expense than if _ten_ letters were so deposited. The time taken in transport is the same. A leather bag covers a thousand letters as easily as a solitary note. It was this fact which led to the reduction of postage. But it was accomplished without the loss of an hour to government, without the enlargement of a coach, or any considerable increase in the compensation paid for the service. It involved no new brain-labor, no new responsibilities, no new expense. Under such circumstances high postage was a folly, and to return to it would be almost a crime. A communication by telegraph, on the contrary, demands a calm, unoccupied brain, and a steady hand to manipulate its contents, letter by letter. A slip of the finger from the manipulating key changes its meaning; a truant thought alters the manuscript; a shadow of forgetfulness mars its whole design. It demands a whole wire for its use, and a given time for its solitary passage. Hence the necessity for multiplying the wires and enlarging the operating staff.
