In addition to what is in the Introduction to Year Book No. I, we suggest that from observation of the class work during the past year, the Seventies have not reached the character of work that may be reasonably expected of them in treating topics of the lessons assigned to them. We have a right to expect that members of our quorums when assigned a lesson, or any part of it, will become such masters of the subject, at least of that part of it assigned to them, that they will be able to make an intelligent presentation of it, clear cut, with a beginning, a middle, and a conclusion to it; and something that will be an intelligent statement at least of the subject, instead of being through with an important topic by a two or three minute statement of it, of which half is apology or excuse. These topics certainly require a ten or fifteen or twenty minute exposition that shall be worth while. And while we would not be severe in our criticism of the past, or too demanding for the future, certainly it can reasonably be expected that Seventies will make some exertion that will give the results here alluded to. We want, in the first place, work; in the second place, work; in the third place, work; and then work; and more work; and better work. That program will spell success. There is no excellence without labor, and much of it. TEXT BOOKS AND AUTHORITIES. Relative to the text books. All of the books recommended in the Introduction of last year's course are available and necessary as authorities in this present year's course, and in addition to these works of reference, a good, General History will be of great service. That of P. V. N. Meyers, prepared for Colleges and High Schools, (Ginn & Company, Publishers, Boston) being perhaps the most desirable, price $1.50. In the Apostatic division of our treatise, Part V, numerous references are made to Ecclesiastical histories and works of a theological character, some of which would be difficult to obtain, such as "Mosheim's Institutes of Ecclesiastical History;" Neander's "History of the Christian Religion;" Schaff's "History of the Apostolic Church;" Mosheim's "History of Christianity in the First Three Centuries;" Hefele's "History of Christian Councils;" "Millman's History of Christianity in the First Three Centuries;" Lardner's "Works," and the like. But "The Students Ecclesiastical History," written by Dr. Philip Smith, author of the "Old Testament" and "New Testament Histories," frequently quoted in Seventy's Year Book No. I, and in this, published by Harper Brothers in two volumes, (price $3.00), is within the reach of all; and on the whole is a very fine Compendium of Ecclesiastical History, quite dispassionate in tone, and generally trustworthy, and brings events down to the death of Luther, 1540.
