played in nearly every theater in America. H. G. Donnelly, well known as a playwright, was also a Pittsburgher. Mrs. Mary Roberts Rinehart is a young author who is coming to the front as a writer of successful dramas, stories, and books. Her plays, "The Double Life" and "By Order of the Court" have been produced, and a novel, "The Circular Staircase," has just appeared from the press.

[Illustration: Margaret Morrison Carnegie School for Women] Rev. W. G. Mackay wrote tales of history under the title of "The Skein of Life." Father Morgan M. Sheedy and Rev. Dr. George Hodges, who used to strive together in Pittsburgh to surpass each other in tearing down the walls of religious prejudice that keep people out of the Kingdom of Heaven, have each given us several books on social and religious topics composed on the broad and generous lines of thought which only such sensible teachers know how to employ. Among Dr. Hodges' books are "Christianity between Sundays," the "Heresy of Cain," and "Faith and Social Service"; while Father Sheedy has published "Social Topics." That devoted student of nature, Dr. Benjamin Cutler Jillson, wrote a book called "Home Geology," and another, "River Terraces In and Near Pittsburgh," which carry the fancy into far-off antiquity. Professor Daniel Carhart, of the University of Pittsburgh, has given us "Field Work for Civil Engineers" and "Treatise on Plane Surveying." From J. Heron Foster we have "A Full Account of the Great Fire at Pittsburgh in 1845." Adelaide M. Nevin published "Social Mirror," and Robert P. Nevin "Poems," a book with mood and feeling. Dr. Stephen A. Hunter, a clergyman, is the author of an erudite work entitled "Manual of Therapeutics and Pharmacy in the Chinese Language." Walter Scott, who, after taking a course at the University of Edinburgh, came to Pittsburgh in 1826, was a very distinguished preacher and author.

His books are: "The Gospel Restored," "The Great Demonstration," and "The Union of Christians." A memoir of Professor John L. Lincoln, by his son, W. L. Lincoln, gives a record of a life so spent that many men were truly made better thereby. Father Andrew A. Lambing, President of the Historical Society of Western Pennsylvania, has written useful monographs on the early history of this region, and he is one of the first authorities in that field. He has also composed books on religious subjects. E. W. Duckwell wrote "Bacteriology Applied to the Canning and Preserving of Food Products."
