We are told, in the Word of God, that one star differeth from another star in glory; yet one that is small may give more light to us than a larger star which is farther away. Some stars are what is called variable, they appear larger at one time than another. Algol, in the head of Medusa, is of this kind. We are told that "the star, at the brightest, appears of the second magnitude, and remains so for about two days, fourteen hours. Its light then diminishes, and so rapidly that in three and a half hours it is reduced to the fourth magnitude. It wears this aspect rather more than fifteen minutes, then increases, and in three and a half hours more resumes its former appearance." I am afraid that many of us are variable stars; if we do sometimes wax dim, it will be well if we regain our brightness as quickly as Algol does. Then there are thousands of double stars. I hope that you will each get a wife who will always shine with you, and never eclipse you, for a double star may be very bright at one time, and sometimes be eclipsed altogether. There are also triple stars, or systems, and quadruple systems, and there are, in some cases, hundreds or thousands all spinning round one another, and around their central luminaries. Wonderful combinations of glory and beauty may be seen in the stellar sky; and some of these stars are red, some blue, some yellow; all the colors of the rainbow are represented in them. It would be very wonderful to live in one of them, and to look across the sky, and see all the glories of the heavens that God has made. On the whole, however, for the present, I am quite content to abide upon this little planet, especially as I am not able to change it for another home, until God so wills it. SUNDAY-SCHOOL AS AN INSTITUTION, What Shall We Do With The.--By George Lansing Taylor, D. D. Fourth edition. Square 16mo, cloth, 30 cents. Paper, 20 cents. THE CENTRAL METHODIST says: "This is the clearest and most vigorous protestation of the whole Sunday-School question in a nutshell we have seen. It is a work that ought to be in the hands of all preachers, since its practical treatment of the difficulties of our present system, and the proper remedy to be applied make it valuable to them." PREACHER'S MAGAZINE, THE.--Edited by Revs. Mark Guy Pearse and Arthur E. Gregory. Published Monthly, $1.50 per year. Single copy, 15 cents. No free samples. Bound volumes, net $2.50. Cloth covers, for binding net, 35 cents. REV. C. H. SPURGEON says: "This unpretentious magazine is as good as the very best of its homiletical compeers. It goes straight to the point, making no big pretences of learning and eloquence, it goes in for practical suggestions, which will be really useful to men who are laboring to win souls. Although we are by this time able to run alone, and make sermons without the aid of homiletics, yet we like such magazines as these, and feel helped by looking them through. Each number is a capital return for the money."
