From that time the growth of the city has been rapid. In 1860, there were 13,395 inhabitants; in 1870, 18,547; in 1880, 21,785; to-day there are probably 24,000. The Honorable Hosea Ilsley was the second mayor; he was succeeded by the Honorable Frank B. Fay, in 1861; by the Honorable Eustace C. Fitz, in 1864; by the Honorable Rufus S. Frost, in 1867; by the Honorable James B. Forsyth, M.D., in 1869; by the Honorable John W. Fletcher, in 1871; by the Honorable Charles H. Ferson, in 1873; by the Honorable Thomas Green, in 1876; by the Honorable Isaac Stebbins, in 1877; by the Honorable Andrew J. Bacon, in 1879; by the Honorable Samuel P. Tenney, in 1881; by the Honorable Thomas Strahan, the present mayor, in 1883. [Illustration: FIRST BAPTIST CHURCH.] In 1849, the railway connected Chelsea with Boston, and in 1857 the horse-cars commenced running. During the Rebellion, Chelsea responded loyally for troops. In the Union army there were sixteen hundred and fifty-one soldiers from Chelsea. Of that number, forty-two were killed in battle; sixteen died of wounds; seventy-five died in hospitals; nine died in Rebel prisons; besides one hundred and four who were more or less seriously wounded. The city also furnished one hundred and thirty-seven recruits for the navy during the war. The city has commemorated those heroes who died for their country, by a very appropriate monument in Union Park. The conservative character of the political fathers of the city may be judged by the fact that Samuel Bassett, who was first elected town clerk in 1849, has served the town and city continuously in that capacity to the present time. For the half-century before his election there had been only three incumbents of the office. [Illustration: Jonathan Bosson's house. Deacon Loring's house. EPISCOPAL CHURCH. Present site of D. & L.
