The choice of subject is of supreme importance. We should study the children whom we are trying to benefit, that we may discover their tastes and learn their interests. We may select a subject in line with the course of school study. This serves not only to illustrate a subject in which the children are already interested, but is an incidental means of making known to the teacher and pupils the usefulness of the library in furnishing reading supplementary to the school studies. We may bulletin a subject of transient interest, thus informing the children along this particular line; or, we may choose a topic which by the novelty of its presentation, may arouse interest in an unfamiliar subject, providing we make sure in choosing that we relate the unknown to the known. We always have a chance of illustrating some one of the universal interests of childhood. Spring and autumn exhibits, bulletins on birds, flowers, and animals, certain anniversaries, etc., invariably prove attractive to children. The bulletins should be such as to satisfy a catholicity of taste and cover a wide range in age and understanding. But whatever be one's choice of subject, let it be carefully thought and wrought out, definite in plan and purpose, and worthy the necessary expenditure of time, material, and effort. It is well to read thoroughly on a subject before attempting to plan a bulletin. The reading of sketchy accounts in children's books is not a sufficient preparation for this work. It is better to turn to more substantial sources that we may penetrate the meaning of the subject for the children, and reflect this in the selection and arrangement of the pictures in the text, and in the talks with the children about the bulletin. We may thus reinforce the message of the bulletin and lead the children to the best book where the information they are seeking may be found. The explanatory text of the bulletin should be direct and simple. Accuracy of statement is essential; this is especially important in scientific subjects. Experiment has proved that a concise and simple account will be read, when a longer statement is passed unnoticed. Poetry may be appropriately introduced to illustrate the thought of the bulletin. We should select the very best poems which will serve the purpose, making sure they are simple and clear enough in meaning to be readily understood by the children. In bulletin work we have an opportunity to acquaint the children with the choicest poetry. In addition to displaying pictures which please the eye, we may also present word-pictures, thus making a double appeal to the mind.
