NOTE TO MAP OK CO\( ORI) 



The material used in tins Mai) "f ("oneoid has been derived from a 

 variety of sources. The town Ixniiids, streets, and residences liave Ihcii 

 taken from a township map of MidcUesex Connty made hy II. F. WalUnp 

 in 185(), reference also being had to a local maj) of Concord by the same 

 engineer, dated KS.VJ, on which credit for the surveys of ^\'hite Pond and 

 Walden Pond is given to " II. 1). Thoreau, ("iv. Eng'." The course of 

 the Concord River is drawn from an elaborate manuscript plan of Tho- 

 reau's, based on earlier surveys, showing the river from East .Sudbury 

 to Billerica Uam. This plan, on which Thoreau has entered the results 

 of his investigation of tiie river in the summer of l.S.7.1, is now in the 

 Concord Public Library. Tlie outlines of Walden and White Ponds 

 have also been taken from Thoreau's original surveys, now in the Con- 

 cord Library. Loring's and Hateman's Ponds are according to surveys 

 by Mr. Albert E. Wood of Concord, and Flint's Pond is from a survey 

 for the t^oncord Water Works by Mr. \\'illiani Wlieeler, also of Concord. 



All names of places are those used by Thoreau, no attention being 

 given to other names perhaps more current either in his own time or at 

 ])resent. Only such names of residents are given as are mentioned in 

 the Journal. 



A few old wood roads, pasture lanes, etc. (Thoreau's preferred high- 

 ways), are indicated, as to their general direction, by dotted lines. 



The irregularity of the northeastern boundary of Concord arose from 

 the fact that when Carlisle was set off from Concord in 17.S0, the farmers 

 living on the border were given the option of remaining within th« 

 bounds of Concord or of being included in the new town. In 1!M);< the 

 Massachusetts Legislature abolished this old division and continued 

 the straight line forming the western half of the boundary directly to 

 the river. 



The identification of localities which were named by Thoreau ai)par- 

 ently for his personal u.se alone has been accomplished, so far as it has 

 proceeded, by a careful study of all the .lournal references to each local- 

 ity, an examination of a large number of Thoreau's manuscript surveys, 

 and an extended personal investigation on the ground. Many of these 

 locjilities are given more than one name in the Journal, and in a few 

 cases the same name is given to different localities. Where doubt exists 

 as to any particular location, the name is omitted from the map. 



Hon. F. B. Sanborn, Judge John S. Keyes, Dr. Edward W. Emerson, 

 the Misses Ilosmer, and others among the older residents of Concord 

 have been consulted in the invjiaration of the map, and have kindly 

 supplied helpful information from their personal accjuaintancc! with 

 Thoreau.
