In 1851, the 23d of February, the Cleveland, Columbus and Cincinnati Railroad was opened for travel; and on the same day forty miles of the Cleveland and Pittsburgh Railroad was likewise completed. These circumstances produced great rejoicings, for during the period of their construction the city had been almost daily adding to the number of its inhabitants, so that it had nearly doubled in the last six years, its population being now 21,140, and in the following year (1852) it added eighty-seven persons per week to its numbers, being then 25,670. In 1858, the new court house was built and the old court house on the Public Square was taken down. We have thus glanced at a few of the leading incidents in the history of the city. A more full and exact account will be found in the historical sketches prefacing each department in the body of the work, and still further details will be found in the biographical sketches. There only remains to be added here a few data in regard to the population, government, and officials of the city. The population of Cleveland commenced in 1796, with four persons. Next year the number increased to fifteen, but in 1800, had fallen back to seven. The subsequent figures are: 1810, 57; 1820, about 150; 1825, about 500; 1830, United States census, 1,075; 1832, about 1,500; 1833, about 1,900; 1834, city census, 6,071, or with Ohio City, 7,648; 1845, 9,573, or with Ohio City, 12,035; 1846, Cleveland 10,135; 1850, United States census, 17,034, or with Ohio City, 20,984; 1851, city census, 21,140; 1852, 25,670; 1860, United States census for combined city, 43,838; 1866, 67,500; 1869, not less than 100,000. The village of Cleveland was incorporated in 1814, and the first president of the village, elected in 1815, was Alfred Kelley. Twelve votes were cast at the election. In the following year he resigned his position, and his father, Daniel Kelley, was elected by the same number of votes, retaining his position until 1820, when Horace Perry was made president. In the following year he was succeeded by Reuben Wood. From the year 1821 to 1825, Leonard Case was regularly elected president of the corporation, but neglecting to qualify in the latter year, the recorder, E. Waterman, became president, ex-officio. Here the records are defective until the year 1828, when it appears Mr. Waterman received the double office of president and recorder. On account of ill-health he resigned, and on the 30th of May the trustees appointed Oirson Cathan as president. At the annual election in June, 1829, Dr. David Long was elected president, and during his presidency a fire-engine was purchased. Forty-eight votes were cast at this election. For the years 1830 and 1831, Richard Hilliard was president, and for the following year John W. Allen was chosen, and retained the position until 1835, one hundred and six votes being cast at the last named election.
