 aged commercial traveler, a well-known agnostic, but a stranger to young Duncan, and a battle royal of argument on religion ensued.

The disciple of Taine and Voltaire was getting the better of the discussion with the young novice, when, leaping to his feet and looking his adversary squarely in the eye, Duncan said: "Sir, you are twice my age. I will ask you on your honor as a gentleman to answer me honestly this question: Here I am a young man. I have grown up in the Christian faith, and am happy in it. Would you advise me to give it all up and come over to where you stand, without God, without faith, and without hope?" "No, young man," said the old agnostic; "when you put it that way, I can not advise you to drop your religion and faith. Keep them and be happy." Duncan retorted: "Don't you see you are standing on a rotten bridge that will break down, while I am standing on a solid bridge? Your heart belies your head, and you admit that your arguments are empty words." (Text.)

EXPERIENCE, VALUE OF

The president of the London Alpine Club said no man was ever lost on the Alps who had properly prepared himself and knew how to ascend them, and when I quoted to him the list of guides who had fallen into crevices and been killed, he quoted back to me a certain passage of Scripture wherein the fate of blind guides and those they lead is set forth in unmistakable terms. "Choose for your guides," said he, "the hardy men who have learned their business thoroughly; who have been chamois-hunters from their youth; who have lived on these mountains from their birth, and to whom these snows and these rocks and the clouds speak a language which they can understand, and then accidents are impossible." (Text.)—

EXPERIMENT

Our most valuable successes usually are achieved on the principle followed by this dog:

In his "Introduction to Comparative Psychology" (1894), Dr. Lloyd Morgan told the story of his dog's attempts to bring a hooked walking-stick through a narrow gap in a fence. The dog "tried" all possible methods of pulling the stick through the fence. Most of the attempts showed themselves to be "errors." But the dog tried again and again, until he finally succeeded. He worked by the method of trial and error. (Text.)

We doubt many theories that are recorded by others, but when we see them proved for ourselves we doubt no longer. A writer, after describing Franklin's first disappointment in investigating the action of oil on water, records his later experiments:

Franklin investigated the subject, and the results of his experiments, made upon a pond on Clapham Common, were communicated to the Royal Society. He states that, after dropping a little oil on the water, "I saw it spread itself with surprizing swiftness upon the surface, but the effect of smoothing the waves was not produced; for I had applied it first upon the leeward side of the pond, where the waves were largest, and the wind drove my oil back upon the shore. I then went to the windward side, where they began to form; and there the oil, tho not more than a teaspoonful, produced an instant calm over a space several yards square, which spread amazingly, and extended itself gradually till it reached the lee side, making all that quarter of the pond (perhaps half an acre) as smooth as a looking-glass."

About all of the great enterprises of mankind are built on earlier experiments that seemed to fail. Hiram Maxim and S. P. Langley each spent laborious years constructing flying-machines that would not fly. Yet those who later succeeded made use of all the important devices that these earlier experimenters had invented.

Some years since it was seen that by damming, controlling, and releasing the waters of the Colorado River in southern
