LITCHFIELD, a county of Connecticut, United States, bounded on the north by Massachusetts, on the east by Hartford, on the south-east by New Haven, on the southwest by Fairfield, and on the west by New York. The face of the country is rough and mountainous; but the soil is good, yielding excellent crops of wheat and Indian corn, and affording fine pasturage. From the inland situation of the county, no maritime commerce can be carried on, and the inhabitants are almost wholly engaged in agricultural and manufacturing pursuits. The population amounted in 1830 to 42,855.
