Although the work of sending and receiving telegraphic messages may be regarded in a general way as partaking largely of a merely mechanical nature, yet it is work to which the operator who is to achieve credit in his sphere must bring much tact, good sense, intelligence, a knowledge of the world, and a considerable amount of patience. Not only are the terms in which telegrams are frequently written so far devoid of context in themselves, owing to the curt way in which they are worded, as to render the sense of little assistance in estimating the correctness of a message received, but the letters of the telegraphic alphabet, being nothing more than little groups of dots and dashes variously arranged, are extremely susceptible of mutilation, owing to any lack of exact spacing on the part of the sending operator. Nor does the liability to error lie only in these directions. The dots and dashes frequently fail or run together, owing either to feeble signals, contact of the wires with one another, with trees, or other objects, or to the instruments not being in perfect adjustment. A grain of grit or of dust getting between the points of contact in a delicate instrument will sometimes do much mischief in the way indicated. There is liability to mistakes, too, in consequence of the handwriting of the senders, or of the operators at a transmitting point where messages have to be again taken down, not being very plain. Yet over and above these tendencies to error, there is the fallibility of human nature, which will sometimes lead a person to write "no" where "yes" is intended, or "black" where "white" is meant; and of such mistakes probably no explanation can be given. So that the work of a telegraphist is beset with pitfalls, and he requires all his wits and a fair share of intelligence to keep him right in his work. It may further be remarked that many errors in telegrams, which might be supposed by the public to be gross or inexcusable, have occurred in the most simple way, or have been shown to be due to failures of a very trifling kind. The following are illustrations of such mistakes:-- A pleasure-party, telegraphing to some friends, stated that they had "arrived all right," but the message was rendered, "We have arrived all tight." The words "right" and "tight" in the Morse code are as follows:-- r i g h t · - · · · - - · · · · · - t i g h t - · · - - · · · · · - In another case, a poor person, desiring to state that her daughter was ill, wrote in her message, "Mary is bad." This was rendered, "Mary is dead," the sense being changed by a slight imperfection of spacing, thus-- d e a d - · · · · - - · · instead of-- b a d - · · · · - - · ·
