The new repute of the educational work of the Modern School attracted the attention of all who appreciated the value of sound instruction. There was a general demand for knowledge of the system. There were numbers of private secular schools, or similar institutions supported by societies, and their directors made inquiry concerning the difference of our methods from theirs. There were constant requests to visit the school and consult me. I gladly satisfied them, removed their doubts, and pressed them to enter on the new way; and at once efforts were made to reform the existing schools, and to create others on the model of the Modern School. There was great enthusiasm and the promise of mighty things; but one serious difficulty stood in the way: we were short of teachers, and had no means of creating them. Professional teachers had two disadvantages—traditional habits and dread of the contingencies of the future. There were very few who, in an unselfish love of the ideal, would devote themselves to the progressive cause. Instructed young men and women might be found to fill the gap; but how were we to train them ? Where could they pass their apprenticeship? Now and again I heard from workers’ or political societies that they had decided to open a school; they would find rooms and appliances, and we could count upon their using our school manuals. But whenever I asked if they had teachers, they replied in the negative, and thought it would be easy to supply the want. I had to give in. Circumstances had made me the director of rationalist education, and I had constant consultations and demands on the part of aspirants for the position of teacher. This made me realise the defect, and I endeavoured to meet it by private advice and by admitting young assistants in the Modern School. The result was naturally mixed. There are now worthy teachers who will carry on the work of rational education elsewhere; others failed from moral or intellectual incapacity. Not feeling that the pupils of the Modern School who devoted themselves to teaching would find time for their work, I established a Normal School, of which I have already spoken. I was convinced that, if the key of the social problem is in the scientific and rational school, it is essential, to make a proper use of the key, that fitting teachers be trained for so great a destiny. As the practical and positive result of my work, I may say that the Modern School of Barcelona was a most successful experiment, and that it was distinguished for two characters:— 1º. While open to successive improvements, it set up a standard of what education should be in a reformed state of society. 2º. It gave an impulse to the spread of this kind of education.
