She bade us adieu, and we went to work to master the language. As Iola and MacNair had informed us, we found it remarkably easy. We had been well trained from childhood in distinguishing all these sounds, and our eyes soon became familiar with the characters by which they were represented, and before we retired to rest after our first day's study, we were practicing the pronunciation of words, and committing definitions to memory. We soon had quite a vocabulary of words at our command, which we introduced into our ordinary conversation. This could be the more readily done, because of the grammatical construction of the language being so similar to the English. Associated as we were, with a number of highly educated people, who understood both languages, our progress was very rapid, and in a short time we could express all of our wants in the language of the country, and when we did not have the right word we substituted English, knowing it would be understood, and also, that some one would supply the right word. We determined from the beginning, to use no language but the Altrurian, just as rapidly as we could acquire it. We used it in reading, writing and conversation, and soon we scarcely thought of our mother tongue, except when we heard it spoken. MacNair and Iola were engaged with their classes an average of two hours a day, and we ordinarily spent our leisure and recreation time together. Our home was also District Headquarters, and here we were continually meeting with representatives from every home in the district, and our acquaintance was rapidly extended. We often visited other homes, sometimes by electric carriage or airship, and sometimes we would walk for miles. When tired, we could always hail a car or carriage. Thus, we were by our associations continually improving in the use of the language, while we were adding to our fund of knowledge concerning the country, by observation and conversation with the people. I carefully studied the economy of the home in which we lived, being assured that this was a sample of a multitude of others. The same thing was true of the district. So in a general way, we were making a study of the entire concave by having a sample submitted to our inspection. At least, I could get a very clear idea of agriculture, the great basic industry that sustains the race, and hence, I am condensing into this chapter the results of a long and careful investigation under exceptionally favorable conditions.
