Besides the American railroads using Baldwin locomotives, engines built in this plant are in use in many foreign lands. There is hardly a part of the world to which one can go where a Philadelphia-made locomotive is not to be seen. [Illustration: THE FIRST TRAIN ON THE PENNSYLVANIA RAILROAD] Philadelphia holds an important place in the construction of high-grade machine tools. She has great rolling mills, foundries, and machine shops, and one of the most famous bridge-building establishments in the world. Her people smile at being called slow; in fourteen weeks a Philadelphia concern made from pig iron a steel bridge a quarter of a mile long, carried it halfway around the world, and set it up over a river in Africa. Shipbuilding in Philadelphia began with the founding of the colony. It was the first American city to build ships and was also the home of the steamboat. The first boat to be propelled by steam was built by John Fitch in Philadelphia in 1786. This was more than twenty years before Robert Fulton had his first steamboat on the Hudson River. Robert Fulton, who was a Pennsylvanian by birth, also lived at one time in Philadelphia. Shipbuilding, to-day, is one of the city's great industries. [Illustration: A PRESENT-DAY LOCOMOTIVE] The art of printing has been practiced in Philadelphia since the very beginning of its history. William Bradford, one of the first colonists, published an almanac for the year 1687. This was the first work printed in Philadelphia. Benjamin Franklin entered the printing business in Philadelphia in 1723, and six years later published the _Pennsylvania Gazette_. This was the second newspaper printed in the colony, the first being the _American Weekly Mercury_, the first edition of which was printed in Philadelphia in 1719. Both of these papers were very small and would appear very odd alongside of the daily papers of to-day. The first complete edition of the Bible printed in the United States was published by Christopher Saur in Germantown, which is now a part of Philadelphia, in 1743. Philadelphia ranks first among the cities of the United States in the publication of scientific books and law books. One of the large publishing houses of the city now uses over a million dollars' worth of paper each year. It is interesting to know that when the Revolutionary War began there were forty paper mills in and near Philadelphia. At that time, and for many years after, it was the great literary center of the country. [Illustration: IN FAIRMOUNT PARK]
