Professor Walling (1825-1888) was an accomplished land surveyor and mathematician.  He joined the firm of Samuel Barret Cushing of Boston and in 1846 became a partner.  In 1850 became a surveyor of towns in New England and established his own company in 1852.  One of his first publications was this map of Middlesex County. Used by land development companies, the map has 69 inserts of towns, 7 vignettes of public buildings, 5 inserts of town directories and statistical tables.  Names of land and homeowners are provided, e.g. notable individuals such as Emerson and Hawthorne in the town of Concord. The maps condition is rated Good [see our rating criteria on the Home Page].  Still attached to its rollers, the map has some damage to the upper right portion caused by the cracking of varnish covering from the cloth backing.  The remaining sections of the map are in good condition.  It measures approximately (61.8"x 61.8"  - 157.0 x 157. 0 cm).    $950.   ($26 shipping / handling / ins.)         New Item
