'Australia,' 'Continent,' 'Britain,' 'South America,' and 'West.' In each section 2,000 operators move down to the central offices each morning at 8 dial, making 20,000 telegraph operators, besides 2,000 in the central section of the whole system, who daily work the keys that flash the millions of messages over the world. This vast throng of employés moves, easily and without impediment, down the cross-streets of their triangles into the diagonals of their squares, and thence to their work. By the system of squares, no employé has a greater distance to walk to his work than the length of the hypotenuse of the triangle whose base and altitude is a half-mile in length; or a little less than three quarters of a mile. One-half of the number of operators go to their dinner at 12 dial, and the other half at 13 dial. At 20 dial, they are relieved, and 10,000 others take their place until 8 dial the next morning. Their work is clean and light; but the hours are long, as it is not practicable to have three sets of operators. Now, for the amusement of the city, there are theatres, dancing-halls, clubs, boating and sea-bathing, libraries, gymnasiums, and many other means of recreation. The greater portion of the operators are married, and live happy and contented in their positions. The finer houses, on the main streets, are given to those longest in service, as a reward for their services. The salary of an operator is sixty dollars per month, and promotion is by competition. I may have wearied you, Mr. Cobb, by going into details as I have," Mr. Doane said, apologetically; "but in order to understand this vast system of communication, with its ramifications extending to every known part of the globe, it is necessary that you should learn how the working force is set in motion and how continued." "On the contrary, Mr. Doane, you have not wearied me at all," replied Cobb. "I can assure you I take special delight in everything tending to better the condition of the working classes. How much better could capital have been employed in my day in building up communities like this, instead of accumulating vast wealth to be fought over by contending heirs." "This, Mr. Cobb," continued Mr. Doane, "is the condition of life and the surroundings of these thousands of men who daily tick the thoughts and wishes of mankind from every part of the known earth. Now, if you are ready, we will take the drag and visit one of the sectional offices, and you can see the actual working of the system." It was but a few minutes' ride from Mr. Doane's residence to the nearest sectional headquarters, and they were soon entering the beautiful park surrounding the four large buildings which faced toward the center. Cobb noticed the air of order and cleanliness which pervaded everything, and the lack of hubbub which might be expected in the vicinity of four buildings holding 2,000 employés.
