Land grant colleges of agriculture -- The Morrill Act of 1862 granted federal land to states to sell, and instructed each state to use the proceeds to endow a college to teach 'agriculture and the mechanical arts.' States not having any federal land within their borders were given 'land in scrip,' permitting them to sell federal land located in other (usually western) states in order to establish an agricultural college. The original schools are called the 1862 Institutions. Subsequently, the Morrill Act of 1890 created the black colleges of agriculture, called the 1890 Institutions. The Elementary and Secondary Education Reauthorization Act of 1994 then gave land grant status to 29 Native American colleges, called the 1994 Institutions.

Land grant university -- The term used to identify a public university in each state that was originally established as a land grant college of agriculture pursuant to the Morrill Act of 1862. In most states the original agricultural colleges grew over time into full- fledged public universities by adding other colleges (e.g., arts and sciences, medicine, law, etc.); in states where a public university existed prior to 1862, the first Morrill Act resulted in a college of agriculture being added to the university. USDA funds go only to the original land grant colleges of agriculture within the so-called land grant universities
