A good chronological chart of the history of any great nation or period is a good thing, and a wonderful help in study. A synchronological chart, giving parallel chronological events in various nations, is much better still. Adams’s chart, now out of print, we believe, was such a chart. One on somewhat the same plan is “Deacon’s Synchronological Chart Pictorial and Descriptive of Universal History,” an English work. But this, too, is out of print. Brother C. Apigian, of Loma Linda, California, has at great pains photographed Deacon’s chart, and mounted these photographs so as to present a continual photographic chart and diagram of the great empires of earth from B.C. 4004 to 1890 A.D., making a continuous chart six feet long by eight inches wide, folding into a bound book of 6x8 inches. Any who are interested may write to Mr. C. Apigian, Loma Linda, California. Brother Apigian is fitting himself for work among his own people, the Armenians.
