of God. The lower love may carry you through a great deal, even torture and cruelty but, my friend, nothing but the supreme love which emanates from the nature of God can ever bear you and me through the stress and storm of our life.

I close with this. Where does the "ought" come in? If you came across the Plain of Lombardy the other day (it lies between the Apennines and the Alps), you must have noticed how rich it is in cultivation and verdure-not that it has any great rivers in it, but it has been so carefully irrigated by canals. There is nothing like God's love except in God, and if you and I are to be irrigating canals in the Sahara of the world, we must bring our nature into open union with the sluice gates, with the Divine nature. You will never get the love in any other way. Love is of God. Love gushes from God. The mother, the patriot, and the socialist may love, but they do not love with the supreme love. It is of God. And the supreme thing for every one of us moral beings is to open the sluice gates of our faith to the very heart of the Eternal, and to keep those sluice gates open, saying, "I can't, but thou canst. My love fails here, but thine immortal, eternal love, the love of the cross, that shall be victorious over all."

Keep those gates open, and direct the flow of this love to the man who does not love you. Look for the man who doesn't love you; look for the man who is an irritant to you, whose nature is out of tune with yours, and direct the flow of God's love against the solid barrier of his nature, until perhaps it disintegrates, it breaks down, and then you are lifted into union with God and have received into your nature something which is not human, but Divine, but which elevates and beautifies and ennobles the one who shall be able to know God. Oh, that wonderful thought, "He that loves, knows God," not by reasoning, but by intuition, as Abraham when he stood by the altar and was about to sacrifice Isaac, became the friend of God.

He knew God. All Paul's reasoning could not have made Abraham know God better. He knew God by the absolute sympathy of a kindred nature and a kindred act. And you, when you sacrifice your dearest self at the call of the love and nature of God, can look God in the face and exchange glances with him, for God and you have passed through the same experience, and yours is the knowledge of a kindred nature and sympathy.

The Sunday-School Exposition

BY THE REV. DR. C. R. BLACKALL, DIRECTOR OF THE EXPOSITION

The Exposition was organized and conducted upon strictly altruistic lines, as set forth in every circular announcement, as follows:

"There is not any commercialism whatever in this Exposition. No contributor, either of merchandise or of money, will receive in return any pecuniary or commercial advantage, directly or indirectly; the reward will come in the consciousness of a great and lasting good accomplished in the uplift and culture of God's needy and faithful coworkers with him. There will not be any mere advertising feature, nor any exploitation of individual agencies, however excellent the latter may be. The single aim will be honestly maintained, to set forth in the most practical and winsome manner the various methods in operation whereby the world's great work of evangelization is being carried forward largely through Sunday-school effort. At the close of the Convention, the material shown will be distributed to all parts of the world by a special commission appointed for that purpose."

The generous response to the appeals made was to the last degree cordial and ample, not only from publishers and dealers in Sunday-school supplies, State and Provincial secretaries, and individual schools, but also from the numerous Foreign Mission fields where Sunday-school effort

of any sort is being maintained. The work of preparation occupied about six months, and required the services of five persons during a large part of that time. The gathering of the material desired was done wholly by correspondence, and its arrangement was entirely under the direction of Mrs. Blackall, the aggregate of separate pieces shown being over seven thousand in number. For the most part this material was mounted on four hundred large pasteboard cards. Included in the aggregate, there were nine hundred and ninety-eight bound volumes and booklets; one hundred and six maps, charts, diagrams, posters, picture and wall rolls; and one hundred and fifty-four pieces of manual work contributed by eleven schools.

The exhibits were classified into sixteen departments, each indicated in three languages: English, French, and Italian. A logical order was followed, with consecutive numbering to correspond with the handsome printed catalogue made possible by the generosity of The Edgell Printing Company of Philadelphia. Starting with the two International Associations, twenty-two State and Provincial Associations followed, which were succeeded by three County Associations and the Organized Bible Class Union. Twenty-nine individual schools came next, followed by collection and advertising methods, certificates, diplomas, and records.

Sunday-school and Missionary maps had a large place, and these were followed by specimen pages of the Bible in all languages and dialects, and these again by Bible training schools and colleges. Four hundred and thirtyfive specimens of music publications, these sub-classified, and representing an output of over nine millions of copies during 1906, were followed by books for teachers, numbering five hundred and sixty-three copies. Sunday-school periodicals were shown from all countries the world over, and in many languages, representing a gross output of more than four hundred and fifty millions of copies
