COMPOUNDS. Prof. (!oss, after an extended European trip last year, whenhe made a careful sUidy of practice and tendencies in railroadwork, in commenting on the compound locomotive, said thatthe four-cylinder type was the only one making progresseither in England or on the Continent. It Is noticeable thatthere is a tendency in the United States to believe that thepossibilities in power and capacity of present methods arevery nearly exhausted and inasmuch as four-cylinder com-.

It is believed by several well-known motive power menthat the four-cylinder, balanced compound offers a greater ulti-mate increase in power than any other type. The reluctance
