it is asked of all ministers, young and old, as they turn over John Bunyan's pungent pages. And every new room, every new bird, and beast, and herb, and flower makes us blush for shame as we contrast our own insignificant and ill-furnished house with the noble house of the Interpreter. Let all our students who have not yet fatally destroyed themselves and lost their opportunity lay the Interpreter's House well to heart. Let them be students not in idle name only, as so many are, but in intense reality, as so few are. Let them read everything that bears upon the Bible, and let them read nothing that does not. They have not the time nor the permission. Let them be content to be men of one book. Let them give themselves wholly to the interpretation of divine truth as its riddles are set in nature and in man, in scripture, in providence, and in spiritual experience. Let them store their memories at college with all sacred truth, and with all secular truth that can be made sacred. And if their memories are weak and treacherous, let them be quiet under God's will in that, and all the more labour to make up in other ways for that defect, so that they may have always something to say to the purpose when their future people come up to church hungry for instruction and comfort and encouragement. Let them look around and see the sin that sinks the ship of so many ministers; and let them begin while yet their ship is in the yard and see that she is fitted up and furnished, stored and stocked, so that she shall in spite of sure storms and sunken rocks deliver her freight in the appointed haven. When they are lying in bed of a Sabbath morning, let them forecast the day when they shall have to give a strict account of their eight years of golden opportunity among the churches, and the classes, and the societies, and the libraries of our university seats. Let them be able to name some great book, ay, more than one great book, they mastered, for every year of their priceless and irredeemable student life. Let them all their days have old treasure-houses that they filled full with scholarship and with literature and with all that will minister to a congregation's many desires and necessities, collected and kept ready from their student days.
