eager that only what is rooted in fact shall claim man's acceptance. Surely it will be the most natural of all natural acts that each should find in the other's work the complement of his own. How grateful should the man of religion be to the man of science for every discovery made in nature when that discovery is amply veri fied, for all thoroughly ascertained knowledge of how the world came to be, for every disclosure of the laws by which a wise God governs his universe! How grateful, too, should be the man of science to the man of religion for every demonstration of the value of holiness, the power of worship, the dreadfulness of spiritual disobedience, and the realized, evident, measured power of prayer in the domain of the spirit! The distrust of our scientific Ephraim would disappear, and the depreciation of our religious Judah vanish away in this chivalrous and cordial appreciation of the essential kinship of each other's work.

For too long-far too long-have men ignored the existence of the bond that binds all lovers of the truth together. For too long have they been marshaled in hostile armies and embittered by unreasonable strife. Is it too much to hope that the coming years are to be made lustrous by a new perception of the spiritual kinship of all men who are searching for truth in any field where it may be found, of the absolute spiritual identity of all results which rest upon what man can verify to the intellect, the conscience, the soul, of the race?

And yet once more: there is an identity of purpose which keeps the man of science and the man of religion at their work. That purpose is the service of our fellows. Sooner or later the results of all true endeavor become the common possession of mankind. Men who never heard of Plato use the Grecian's arguments when they talk politics, and are moved by his ideas when they dream of a social heaven on earth. There is no conception of truth too lofty to be translated into the vernacular of the multitude. In the universities have been born nearly all the great movements of modern times, however difficult it be to track them back to their source. And no brilliant discovery has ever been made by astronomer, chemist, geologist, electrician, mineralogist, or engineer that has not finally been turned to account in the utilities or adornments of life, or does not hold the promise of it before our eyes. The generous support which the public gives to all its schools of technical

art is the public's testimony to its faith in their value as contributors to the public stock. Every man who is discovering what is, but has been concealed, is serving his fellows. Every man who is finding new uses for old material is adding to the common capital. Every man who is eliciting and applying force is increasing the general power.

To furnish humanity with new tools wherewith to work richer results; to remove every obstacle to the freest play of all man's powers; to lessen danger and wear and waste; to increase safety and health and skill; to give ignorance and weakness a chance; to make everything that is helpful and pleasant plentiful - that is the purpose of those who are imagining and executing the astonishing things which signalize our day. I will not believe, on any evidence thus far offered, that the motive of our modern energy in the realm of physical science is a sordid eagerness for gain or a vulgar craving for fame. The man who discovers a new use for common material or a new application of an already measured force should be the man who feels the thrill of happiness of him who can stop the throbbing of a nerve or clear the perplexity of a bewildered brain; and more often than much shallow and foolish talk would lead us to believe, he is that man. The comforts and conveniences of life which strip toil of its harshness and multiply our personal force may be the instruments of spiritual culture, as, indeed, thousands are ready to testify they have found them to be. It ought to be so clear that no one need miss it that the men who bridge the stream and plan the house, who mine the coal and forge the steel, who compel the electrical force to turn a wheel or to blaze in light or to weld iron bars, are the servants of the people, and are furnishing them with the conditions under which fullest vitality is possible. And what said Jesus to his friends when they were debating the question of superiority among themselves? Who is greatest in the kingdom of heaven? The man who serves. He who gives a cup of cold water only shall not lose his reward. But what of him who brings down from its home among the beautiful hills, before subtle poisons have mingled with its limpid streams, the crystal water into every home of the city with a baptism of cleanliness and health shall he lose his reward? He truly served his fellows and takes his place in the ranks with all who have made the life of man richer, fuller, stronger, whether by science

or by religion. He has been obedient to the great law of service as truly as were Luther and Wesley, Hampden and Lincoln, Raphael and Beethoven, Shakespeare and Browning, Savonarola and Phillips Brooks. Just as truth unites by a real instead of an artificial bond all lovers of the truth, so does obedience to the law of service make brothers of those who serve, whatever be the sort of service given. And when, as is always possible, they who have set themselves in any field to the cultivation of any fruit for the refreshment and sustenance of their fellows shall see that in Jesus Christ what man should be, nay, what man may become, is the noblest vision of the perfect man, then each of us shall be most profoundly moved to give our service from a motive so high and pure and lasting that the Republic, Utopia, the Kingdom of Heaven — call it which you will-shall be established on this earth, prepared to receive the New Jerusalem, the city of God, which hangs in the heavens over us ready to descend when the earth and man are fitted for its coming.

Gentlemen of the senior class, you stand to-day on the summit of the privilege of your years of discipline and training. You look back with gratitude, tinged with regret, perhaps, for days when faithfulness slackened; with a quickened throb of the heart that close ties and happy friendships are no longer to be strengthened and fed by daily companionships. But you look far down into the future that is beckoning you with its glowing hands. It is all bright with expectation and illimitable hopefulness. It ought to be. No one who has been young and still keeps his sympathy with youth would have it otherwise. Pausing for one quiet moment here in the quiet church you have heard of the essential nature of the work you are going to do. We send you out as searchers for truth and servants of men, who in that search and service are, by obedience to the law and love of God, to become yourselves the splendid illustrations of the power of truth, the nobility of service. The world wants you for the same reason that it wants the ministers and lawyers and doctors who shall be graduated next month across the Charles. It is counting upon you. It has been waiting for and calling you. And now you are ready. May God's blessing ever be with you, keeping your love of truth pure, your service noble. Accept the terms which truth and service offer you, "then burn to the socket!"

THE 445th meeting of the SOCIETY OF ARTS was held at the Institute this day at 8 P.M., Mr. George W. Blodgett in the chair.

The records of the previous meeting were read and approved. Mr. David J. Cartwright, of Boston, was duly elected an Associate Member of the Society. The Chairman then introduced Captain William Brophy, of Boston, who read a paper on the "Fire Hazards of Electricity." At its close the Chairman introduced Mr. H. S. Parshall, of the General Electric Co., who read a short paper on the same subject from the point of view of the producer of electricity. The papers are published in the present number of the Quarterly. An interesting discussion followed, after which the thanks of the Society were extended to Captain Brophy and Mr. Parshall, and the meeting adjourned.
