Among the places deeply interested in the work of putting reproductions of great pictures into the schools are Athens, Bellefontaine, Findlay, Fostoria, London, and Hamilton.

The Pallas Club in Athens assisted by other organizations, gave an entertainment, "The Old Maids' Convention," last February, for the benefit of the Athens schools. These workers cleared one hundred and five dollars, and this has enabled them to make their eleven school-rooms more attractive.

In Bellefontaine the primary teachers, ten in number, with the help of the music teacher, have given a successful public entertainment, the entire proceeds of which have been spent in pictures and other works of art.

A short time ago an Art Club in Findlay gave an exhibition of pictures procured from different firms with the understanding that they sell them if possible. The children were given tickets to sell and in consequence each schoolroom has received a picture. The room that sold the most tickets had first choice. The pupil who sold the greatest number was given a large picture, "A Scene on the Nile."

Owing to the leadership of Miss

Thomas, teacher of drawing, Fostoria is one of the pioneers in this movement in Ohio. Three years ago she had an exhibition of pictures, and as a result two hundred and fifty dollars worth of pictures was placed in the schools. Last month a second exhibition was held. Miss Thomas secured the hearty co-operation of the five Literary Clubs of the city. The entire community was benefited and the children were blessed with many new pictures. But the good work does not stop here; one of this teacher's kind friends has presented her with a magic lantern which will be a great aid in picture study. Miss Thomas is certainly to be congratulated.

In February through the efforts of the teachers in London an exhibition of the Helman-Taylor pictures was given closing with a delightful reception. The proceeds enabled the committee in charge to buy one picture for each room. All are enthusiastic over this beginnig and hope it will lead to better things in art for their schools.

The Helman-Taylor art exhibit which was brought to Hamilton under the auspices of the Club of Woman Teachers was a sucess both as an educational feature and as a means to obtain funds to buy pic

tures for the school-rooms. The superintendent, S. L. Rose, was in sympathy with the movement, and in order to awaken an interest among the pupils he placed the penny Perry Pictures in their hands four weeks before the exhibition and instructed the teachers to occupy a short period each day in explaining the pictures and giving the most interesting points about

the master painters. The awakening not only among the children but the parents as well was truly marvelous. The Literary Clubs were given certain days, and they took entire charge of the days assigned them. The magnificent sum of eight hundred and seven dollars was cleared and five hundred dollars were added by popular subscription.

In answer to some questions and criticisms regarding my statements in an article entitled, "Hot Ice," I wish to say a few words.

Mr. Marshall asks how it is that a pane of glass which does not intercept the radiations from the sun does intercept those from the stove. The implication in this question is not absolutely true in either case. Some of the light waves are absorbed by the glass, as I said, and also some of the radiations from the stove are transmitted. The radiations from the sun are all alike except in the length of the wave. The shortest wave which we can see is the violet and the longest which can affect the eye is red.

These red waves are the warm waves, but in the infra-red, where the waves are still longer, they are

warmer.

Now glass and water are both

quite transparent to short waves, but opaque to the longer ones. The air holds a great deal of water vapor and on this account only about 50 per cent of the heat waves, in our latitude, reach the ground. The glass through which the sunlight flows is quite transparent to most of the solar radiations which have escaped absorbtion by the air and so it is not rapidly heated, but when these waves come in contact with some object in the room which is opaque to all, then they can by a cumulative effect produce a molecular agitation which we call heat.

In case of a hot stove most of the radiations are the kind to which

glass is opaque, so that the glass is rapidly heated and but little is transmitted.

A good example of this can be observed in a hothouse where the sun's radiations, which easily pass

down through the glass roof, will quicken the molecular activity of the opaque soil and the soil then begins to radiate long waves such as come from a stove, but now it finds its exit blocked by this same glass roof and so the heat accumulates inside.

Again, Mr. Marshall asks what transmits the energy if there are no molecules between our air and the

This question presumes that if there are no molecules there, then nothing is there. This conclusion by no means follows. There are many strong evidences that all space, so called, is filled with a homogeneous solid called ether, in whcih molecules of material substances are imbedded.

Scientists are forced to this assumption as the only conceivable. way of explaining many observed facts. As long as it continues to explain phenomena it is a legitimate and scientific assumption. Of course we can not know ether by the senses, but, as Lord Kelvin said in his lecture at Johns Hopkins University: "Instead of beginning by saying that we know nothing about the ether, I say that we know more about it than we do about air or water, glass or iron; it is far simpler; there is less to know. Its natural history is far simpler than that of any other body."

It is on this ether that radiant energy from the sun and other bodies is carried in undulatory

waves. This wave is the thing that moves and carries the energy and when the wave is arrested the energy is expended in the production of the various prenomena of heat, light, chemical changes, etc.

With these things in mind I can not see that I have made any "statements of mutually destructive propositions."

Again, I must still claim that it is unscientific to say that heat passes from a stove to one's hand held near by, because it is not in accordance with scientific observation and analogy. An incandescent bulb contains only one-millionth of the air which it held before it was pumped and would be even better if all were pumped out and yet the radiations from the hot filament traverse this space to the glass and heat it hot enough to char wood upon which it may be placed. We know that heat is in the filament and in the glass. There is no conductor of heat between, for heat is molecular motion.

It may be unscientific also to say that light passes from the sun to the earth, but this will depend on your definition. If light is a vibration of ether which may be appreciated by the eye, then the statement is correct, but if light is the appreciation of this vibration then it is incorrect.

Of course there are many things not yet well known about these subjects, but patient experiment has revealed much that is reliable.

small house in which this unique and interesting personality by the name of Daniel Decatur Emmitt lives, was made, and an exceedingly pleasant and satisfactory interview was had. The old gentleman received us most kindly, and talked very freely of the many interesting events which have crowded thick and fast into his rather re

markable career. Believing that something of his history and of the song which made him famous will be interesting to the readers of the MONTHLY and the teachers and pupils of Ohio, we gladly publish the following summary of the many statements made to us by "Uncle Dan" as he is familiarly called by his neighbors and friends. Daniel Decatur Emmitt was born at Mt. Vernon, Ohio, October

29, 1815. As has frequently happened since, Dan was sent to school as he himself expresses it, more to get him out of the way at home than to give him an education. He fared reasonably well until about thirteen years of age when he was compelled to work all his spare time morning and evening blowing the bellows in his father's blacksmith shop. This work seriously interfered with the home task assigned him each day at school of learning to spell a long list of words in Webster's spelling book which at that time held an important place in the course of study. The penalty inflicted in school for not learning his spelling lesson was invariably a whipping which was just as certainly followed by another at home because he had already been whipped in school. The parents and teachers seemed to work in perfect harmony so far as this part of his education was concerned. The branches taught in the schools which he attended were spelling, grammar, arithmetic, through the fundamental rules, and geography. The method of studying geography as described by "Uncle Dan" was as follows:

"Our parents would make us straddle a mule and ride over the country to see where the principal cities were located." It seems in place to observe at this point that even in that day the much-talkedof "laboratory method" was in use.
