"By degrees I made a discovery of still greater moment. I found that these people possessed a method of communicating their experience and feelings to one another by articulate sounds. I perceived that the words they spoke sometimes produced pleasure or pain, smiles or sadness, in the minds and countenances of the hearers. This was indeed a godlike science, and I ardently desired to become acquainted with it. But I was baffled in every attempt I made for this purpose. Their pronunciation was quick, and the words they uttered, not having any apparent connection with visible objects, I was unable to discover any clue by which I could unravel the mystery of their reference. By great application, however, and after having remained during the space of several revolutions of the moon in my hovel, I discovered the names that were given to some of the most familiar objects of discourse; I learned and applied the words, 'fire,' 'milk,' 'bread,' and 'wood.' I learned also the names of the cottagers themselves. The youth and his companion had each of them several names, but the old man had only one, which was 'father.' The girl was called 'sister' or 'Agatha,' and the youth 'Felix,' 'brother,' or 'son.' I cannot describe the delight I felt when I learned the ideas appropriated to each of these sounds and was able to pronounce them. I distinguished several other words without being able as yet to understand or apply them, such as 'good,' 'dearest,' 'unhappy.'
