A true and careful consideration of these points will prevent trouble later on. I will take up the next consideration of the operating expenses of such a plant. I propose to take as a representative type, showing the present development and first-class work, the station of the Edison Electric Illuminating Company, of Brooklyn, which was completed last fall, and is now in successful operation. Having thus generally outlined this plant, we will now turn our attention to the consideration of other points in connection with it. The wood paneling was new, and Ford's Iron Mountain, Michigan, plant now produced the wood bodies and shipped them directly to the various Ford assembly plants. I Desire to present to you a brief review of the present and prospective future of central power plants in the larger cities, taking as an illustration one of the more recent types, describing its general arrangement, then proceeding to the consideration of its initial cost, earning capacity, output, operating expenses and economy, and, in conclusion, what are electric cables trying to indicate the immediate future development in this class of work. In order to place the company (m an earning basis we have to secure to start with a certain number of lights or an equivalent in lights and power to clear the necessary general and operating expenses, which will exist regardless of the smallness of the load; in other words, we must have for such a capacity-plant not less than 5,000 lights with an average income of $8 per light per year to clear the general incidental and operating expenses.



The average income per light in stations of this class varies in different parts of the country and with different loads. The maximum number of lights lighted at any time in proportion to the number connected is very good for such -work and shows a good class of business. It is only thus that we can hope to obtain a business and establish ourselves on the commercial basis which gas light companies have placed themselves in the past years, and thereby secure to our stockholders the returns for which they have invested their capital. On the top floor we have the offices, supply rooms and workshops of the company. On the rear of the second floor are located the coal storage, water-tanks and feed-water heater. Everything in connection with handling, generation, and furnishing of current is directly under the eye of one man in this gallery, and from which he has a general view of the dynamo-room floor and the workings of the dynamo, a second man being on the floor to see to the bearings and brushes.



Ascending to the second floor, we reach the electrical part of the plant. Sixth-Flexibility of system; that is, adaptation to furnishing current for light, power and other sources of revenue, the obtaining of the largest return per dollar invested, and not carrying to excess for the mere sake of engineering in any part of the plant but the obtaining of proper results therefrom. The boilers are Babcock & Wilcox's largest type of sectional water-tube boilers. All circuits of this plant are underground, there being about twenty-five miles of underground conductors. It stretches a mind-boggling 22 miles (36 kilometers) across the Qiantang River at the Yangtze River Delta on the East China Sea. Seventy people were killed when the Tay Bridge, which spanned the Tay River in Scotland, came down in gale-force winds on Dec. 28, 1879. And the Tacoma Narrows Bridge collapsed just four months after it opened on July 1, 1940, from high winds.



These pocket televisions came out around 1966, and they have only been getting better. We have got to recognize the fact that the public, to a certain extent, have become prejudiced, in a measure, somewhat unjustly; but this is all the more reason for better and more conservative management and giving them good construction. No more inviting field is offered for either investing capital or good engineering than a central station for lighting, power and railway work. Mixing them is never a good idea. We have obtained a load diagram, taken from this station, which gives a fair idea of the changes and variations here taking place. A careful analysis of all the items covered in these expenses in such a station as this one, gives the following result: That the fixed expenses are seventy-five per cent, of the whole, and the variable twenty-five per cent, approximately; or, in language which may appeal more directly to you, if we double our income or business, we only increase our expenses 25 per cent. The platform is moored with four lines, two of which are connected to the column stabilizing the turbine, which helps to reduce excess motion. Each engine is directly belted to two generators.
