As the International Sunday-school Lessons for the last half of 1908 will be upon Old Testament subjects specially treated in “Patriarchs and Prophets,” the present time is very favorable for the sale of this book to thousands of Sunday-school attendants, teachers and workers. “Patriarchs and Prophets” contains the foundation principles of the message, and interweaves them in the biographies of the leaders of Israel mentioned in the coming Sunday-school lessons, in a manner that will guide those studying these lessons into the full gospel for this time. While the circumstances are favorable, a special effort should be made to give the people this “meat in due season.” Send to the Review and Herald for free copies of “Helpful Hints,” which contains the topics of the International Sunday-school lessons, and the pages in “Patriarchs and Prophets” where these lesson topics are mentioned. “Patriarchs and Prophets” is an elegant book in every particular. It is published in the English, Danish-Norwegian, Swedish, German, and Holland languages, and substantially bound in all the popular styles of binding. It contains 760 large pages; prices, $2.25 to $4.50. Order of the State Tract Societies, or of the Review and Herald Publishing Company, Battle Creek, Mich.
