Candidate passages:
East Florida was a colony of Great Britain from 1763 to 1783 and province of Spanish Florida from 1783 to 1822.
East Florida was established by the British colonial government in 1763; as its name implies it consisted of the eastern part of the region of Florida, with West Florida comprising the western parts.
Its capital was St. Augustine, which had been the capital of Spanish Florida.
Britain formed East and West Florida out of territory it had received from Spain and France following the French and Indian War (the Seven Years' War).
Finding its new acquisitions in the southeast too large to administer as a single unit, the British divided them into two colonies separated by the Apalachicola River.
East Florida comprised the bulk of what had previously been the Spanish territory of Florida.
Britain ceded both Floridas back to Spain following the American Revolutionary War, and Spain maintained them as separate colonies, though the majority of West Florida was gradually annexed by the United States.
Spain ceded East Florida and the remainder of West Florida to the US in the Adams-Onís Treaty; the United States organised them as a single unit, the Florida Territory. 
In February 1883 the West Florida Seminary became part of Florida University, the first state university in Florida.
Under the new university charter, the seminary became the institution's Literary College, and was to contain several "schools" or departments in different disciplines.
However, in the new university association the seminary's "separate Charter and special organization" were maintained.
Florida University also incorporated the Tallahassee College of Medicine and Surgery, and recognized three more colleges to be established at a later date.
The Florida Legislature recognized the university under the title "University of Florida" in Spring 1885, but committed no additional financing or support.
Without legislative support, the university project struggled.
The institution never assumed the "university" title, and the association dissolved when the medical college relocated to Jacksonville later that year.
However, the act recognizing the Tallahassee institution as the "University of Florida" was not repealed until 1903, when the title was transferred to what had been the Florida Agricultural College.
However, the West Florida Seminary, as it was still generally called, continued to expand and thrive.
It shifted its focus towards modern-style post-secondary education, awarding "Licentiates of Instruction", its first diplomas, in 1884, and awarding Bachelor of Arts degrees in 1891.
It had become Florida's first liberal arts college by 1897, and in 1901 it was reorganized into the Florida State College with four departments (the College, the College Academy, the School for Teachers and the School of Music). 
 University of Florida: Numerous works within what was recognized in 1989 on the National Register of Historic Places as the University of Florida Campus Historic District, bounded by W. University Ave., US 441/SW.

Anderson was recognized by the United States Congress in 2003 as one of two official visual artists for the Year of the Blues. 
As early as 1912, the area surrounding Crane Creek was being advertised as prime real estate for agricultural development, and efforts were already underway to enact drainage projects in the area.
By 1919, Chapter 298 of the Florida state statutes was enacted, allowing for the creation of drainage improvement districts.
Two year later, on April 5, 1922, the Crane Creek Drainage Improvement District was officially filed by the Secretary of State of Florida, and bids were sought in the summer of 1922 to begin canal development.
Through 1927, the initial canal construction resulted in the building of what would become the Crane Creek Canal (M-1), along with various feeder canals.
The new canals drained an area previously part of the St. Johns River basin (west of the low Atlantic Coastal Ridge), redirecting the flow of water eastward into Crane Creek and ultimately the Indian River.
The interbasin canal diversions are estimated to have added 5,040 acres to Crane Creek's watershed.
Presently, the Crane Creek Canal (M-1) runs from Sarno Road south along I-95 to just north of US 192 before heading east and eventually merging into Crane Creek on the campus of Florida Tech, just west of SR 507 Babcock Street.
The Crane Creek Canal is fed by multiple secondary and leveling canals designated L-1 to L-16.
