Most of the county's soil is glacial deposit, except that in the valleys of the rivers. Those streams include the Wabash River which flows west across the county, dividing it into two almost equal portions; what is known as Little River joins it west of the center of the county; another Small river, the Salamonie, cuts off a small portion of the southwest corner of the county and joins the Wabash River soon after leaving Huntington County. Because of the fertility of the soil farming, fruit growing and stock raising are chief occupations of the people.. Due to its very fertile soil, Huntington County is another of the essentially agricultural districts. Located in the northeastern section of the state, it comprises 386 square miles and is divided into twelve townships.

The first organization of a library for Huntington occurred in the year 1874. It was called the Public School Library Association. The yearly membership fee was $2. The Central School building gave space for the books constituting the library, which in a short time possessed over 1,200 volumes, many of which had belonged to the famous Mechanics' and Working Men's Library, established by William McClure, who founded the New Harmony Library. A number of these books, bound in sheepskin, and bearing on the cover the words, "Mechanics' and Working Men's Library," may still be seen in the present library.

In 1889, the library was reorganized under state laws, making it a free library, thus reaching more people. In January 1902, the school board formally accepted Mr. Andrew Carnegie's offering of $25,000 for the erection of a library building and donated the site. This building as it now stands, represents the sum of about $29,000. This includes recent additions and improvements. The building was first open to the public February 21, 1903 and in 1915 contained about 24,000 volumes.

Outstanding among the personages of importance to the county have been John Tipton, who owned much of the land; Tipton's agent, the Elias Murray; and later, Major General James Richard Slack, Great Civil War soldier and Circuit Judge.
