On page 100 of the Records of the Town of Brookhaven, 1856-1885 is recorded a "survey of a four rod public road from the road out of Fireplace Neck across the upper crossing of Beaver Dam Brook west to Marvins house in the Hollow -- Magnetic Course."  This road was the road now known as South Country Rd., and its right-of-way was 66 feet (4 rods).

This survey is useful as it indicates some of the residences on the road at that time, and their exact locations. The table below records the actual surveyor's dimensions, and the map below is drawn from these dimensions.   N. Miller, Jr. was the Surveyor.  While there is not a date recorded for the survey, it is likely conducted in July 1858, as its record immediately follows the one dated 20 July 1858 for Beaverdam Road.

There are some differences between the houses indicated on the survey and the houses indicated on the 1858 Chace map.  "Lodowick Riders" house is not indicated on the Chace map (although it may have been either the "Bartow" or "Smith" houses identified by Chace -- the "Smith" house being most likely.).  The house identified as Charles Emmons on the survey was identified as C. Emmonds on the Chace map.  And the "Joseph Marvins" house used as the anchor for the end-point on the survey is not identified on the Chace map, but is likely one of the unidentified structures near the house labeled "J. Rider."  It is interesting to note that Joseph Marvin does not appear on the 1850 or 1860 censuses, suggesting that he had but a brief sojourn in Fire Place.

The survey started "for the centre of the road from the S.W. corner of Timothy Ketchams main house, south 75° W. one chain & 34 links...."    A surveyor's "chain" is 66 feet (or 4 rods); each chain contains 100 links (7.92 inches).  Each "survey section" is labeled on the map.
