 MIR. HOPKINS ADDRESS.
 MT. Chairman, Ladies and Gentlemen: I have no intention at this time to de- liver any scientific or technical dis course, or a brilliant address, for the subject is a light one, and I cannot do so. But, 1 am in hopes to be able to entertain you for a short time on the subject of light. This theme I think we should all be interested in from the fact that light is a symbol of warmth and life, and life means action which brings progress and knowledge, while it's op- posite stands for inaction, coldness, death
 Lightmay be divided into two classes: First, natural; second, artificial. It will be my endeavor at this time to speak more about the latter A moment spent on natural light will not be out of place, however. Natural light Is derived from three sources, the sun, the moon and the various stars. When the sun ap- pears on the horizon the lesser lights, the moon and the stars are overpower- ed and we enjoy that blessing which we call daylight. This is in obedience to the command of God Let there be light" and as yet no man has been able to control these three lights; neither has any one be able to fathom the mys- teries of their paths. They are held in control by an All-Wise Creator for the comfort of His creatures.
 Artificial light is derived principally from three sources, first from electrici- ty; second from that chemical action which we call combustion, and lastly, from friction. We have an example of light from electricity in the arcs on our streets, and the incandescent in- doors. From combustion, the light from gas, oil, candles, wood etc, and from friction by the rubbing together of two pieces of flint, or loaf sugar. Of course, these three ways are sometimes com bined, as for example, the friction by rubbing the fur on cats back, which q of 7, ation; or the friction made by striking match creating the chemical action which ignites match. Other examples might be quoted, but these will suffice.
 We cannot realize that this world would be without artificial light, or even with the poor artificial lights that our ancestors used, for it is nearly possible in this age to have a continu- ous day. We are told that the earth was formed and man In his primitive state created and placed upon It. His wants were few, simply food, raiment and a place to sleep. A cave served as a shelter by night from the cold and dampness, and as he clipped the ar rows from the flint rock with which to kill the fish and animals for his food, he noticed the spark which flies out and quickly vanshes A gleam of surprise doubtless, came over his face He tried again and again, and then became aware of the fact that he had found a way to create fire, which would cook his food and warm his home In the rocks or earth. And thus by the smol- dering fire he made the first step to- ward producing artificial light. Again in cooking his food he discovered that the fatty portions while burning creat- ed light. So these he tried to use tc light his home, but he had no lamp A shell from the sea shore, or perhaps the skull of the animal he had killed for food and raiment served his purpose And thus the first lamps were made and as man progressed in knowledge he discovered that the fruits, nuts and berries of various kinds would produce an oily substance, and that with the clay he could fashion a lamp after his own design. So he cultivated the trees
