Richard W. Ringgold, the principal of the school from 1832 to 1854, seems to have been a man of ability, and under him the number of students so much increased that in 1843 it was resolved to rebuild the college on the old site and to revive the college course. As a result, the present main building was erected, the corner-stone laid with imposing ceremonies on May 4, 1844, and the college was reopened in its own edifice on January 1, 1845. In 1849, a class of four was graduated, and in 1854, two additional buildings were erected; one for the Principal's residence and the other for dormitories and recitation rooms.
The college continued prosperous during the second administration of Rev. Dr. Waters from 1854 to 1860; but in the presidency of his successor, Rev. Andrew J. Sutton, came the Civil War, depriving the college of its Southern constituency and distracting men's minds from learning. After the Rebellion, an unfortunate selection of teachers and laxness of discipline caused the college to lose still more ground, and Wm. J. Rivers, Principal from 1873 to 1887, had much to do to build it up again. He was a faithful and diligent teacher, and under him the moral tone of the college was improved and the course of instruction enlarged. The present head, C.W. Reid, Ph.D., is still further advancing the cause of the institution and a new career of prosperity seems opening before Maryland's oldest college and the only one on the Eastern Shore of the Chesapeake Bay.
St. John's College, like its sister institution, founded on a non-denominational basis, started out under even fairer auspices.[9] It was granted, by the State, Governor Bladen's mansion and four acres of land surrounding it, was made heir to the funds of King William's School, and secured £9,000 from private beneficence in the first two years of its history. The Bladen mansion, now known as McDowell Hall, was repaired and enlarged and, on August 11, 1789, Bishop Carroll was elected president of the Board of Visitors and Governors and Dr. John McDowell accepted the Professorship of Mathematics. After unsuccessful attempts to obtain a principal from England, Dr. McDowell was chosen to that position in the following year and continued in office, until the State withdrew its aid to the college in 1805. He was a man of great learning and was very successful at St. John's and later at the University of Pennsylvania as provost. Under him, St. John's flourished greatly and many men of a national reputation were enrolled among its students, from the time the first class graduated in 1793.
