It is also interesting to note that the coal consumption perkilowatt hour output was lbs. during the test. The test wasmade at full load and this lbs. is the coal consumption underthe most favorable conditions. In practice wdiere the load is constantly fluctuating, and issometimes but a small proportion of the full load for considerableperiods, a very much larger coal consumption is to be expected. 436 STREET RAILWAY JOURNAL.

Here variousremedies are possible, such as the use of more copper,the installation of a storage battery auxiliary plant, thebooster system, or a separate station. Some one of theseremedies should certainly be adopted wherever schedulesare slow, or are being materially interfered with on holi-days or other times of special service. In Quincy, Mass.,which is the center of an extensive network of streetrailway lines extending a long distance in several direc-tions, certain of these lines have suffered greatly fromlack of power, and the serv
