The whole or nearly the whole of the eight months when I was not employed was not lost. I read many volumes in history, voyages, and travels, politics, law and Philosophy. Adam Smith and Locke and especially Humes Essays and Treatises, these latter I read two or three times over, this reading was of great service to me, it caused me to turn in upon myself and examine myself in a way which I should not otherwise have done. It was this which laid the solid foundation of my future prosperity, and completed the desire I had always had to acquire knowledge.
