  • History of New Haven County, Branford Chapter, by J.L. Rockey
    HISTORY OF NEW HAVEN COUNTY, 1897 VOLUME II, Chapter I, The Town of Branford J.L. Rockey Settlement and Early History—Civil Government—Town Officers—Town Buildings—Branford Borough—Probate District—Public Highways—General Industrial Interests—Branford Village—Beach and Shore Resorts Branford is one of the shore towns of the county. It is between seven and eight miles, along the sound, between Guilford on the east and East Haven on the west. From North Branford south to the coast line the distance is between four and five miles. The surface is uneven, there being in some localities high hills. Many of these having a smooth surface, are tillable to the summit. In the western part some of the Branford hills attain considerable elevation and are designated by local names. In the southeast outcroppings of granite are manifest and the soil is less fertile than in other localities. Along Stony creek that rock has been extensively quarried for building purposes. That stream empties into the sound at a cluster of numerous islands, several hundred in number, large and small, called Thimble Islands. Farther west is still another cluster, called Indian islands. The streams are small, Branford River, flowing through the central part, being the most important. Near the sound its course is winding, and for several miles it is a tidal stream, admitting vessels of from 50 to 75 tons burden. In the vales and lowlands the soil is strong and very productive. It has been found, with proper fertilization, to be admirable adapted for garden crops, and a number of inhabitants have lately engaged in that pursuit.
