I shall not have time to speak of the work of the older children, where the original crude instincts of construction and communication have been developed into something like scientifically directed inquiry, but I will give an illustration of the use of language following upon this experimental work. The work was on the basis of a simple experiment of the commonest sort, gradually leading the children out into geological and geographical study. The sentences that I am going to read seem to me poetic as well as “scientific.” “A long time ago when the earth was new, when it was lava, there was no water on the earth, and there was steam all round the earth up in the air, as there were many gases in the air. One of them was carbon dioxide. The steam became clouds, because the earth began to cool off, and after a while it began to rain, and the water came down and dissolved the carbon dioxide from the air.” There is a good deal more science in that than probably would be apparent at the outset. It represents some three months of work on the part of the child. The children kept daily and weekly records, but this is part of the summing up of the quarter’s work. I call this language poetic, because the child has a clear image and has a personal feeling for the realities imaged. I extract sentences from two other records to illustrate further the vivid use of language when there is a vivid experience back of it. “When the earth was cold enough to condense, the water, with the help of carbon dioxide, _pulls_ the calcium out of the rocks into a large body of water where the little animals could get it.” The other reads as follows: “When the earth cooled, calcium was in the rocks. Then the carbon dioxide and water united and formed a solution, and, as it ran, it _tore_ out the calcium and carried it on to the sea, where there were little animals who took it out of solution.” The use of such words as “pulled” and “tore” in connection with the process of chemical combination evidences a personal realization which compels its own appropriate expression.
