During yesterday's visit, all three "tack in lead" RMs were found as described, except that RM1, reported as 22.6 ft. from the station was measured at 22.9 ft.
This recovery was made possible by Curt Crow, the Massachusetts NGS coordinator from MassHighway (which now performs the functions of the former MAGS), who supplied me with the 1935 MAGS data cards, documenting the bearings and distances of the RMs, as follows:
RM1 distant 22.6 ft., bearing 187dT 17' 16" (but see above)
RM2 distant 20.8 ft., bearing 277dT 11' 28"
RM3 distant 8.2 ft., bearing 329dT 38' 23".
The carded bearings, given from the South under NAD 27, were 180d less than those reported above.
The azimuth mark for this station is HAYES HILL, 1891, which bears 182dT 21' 47.7" from the station.
Even with this precise information, the recovery was difficult, due to the depth of thatch and accumulated soil on top of the ledge (see photos) and the fact that the leaded drill holes had discolored quite a bit, after being covered for the past 74 years.
Given that the station is now surrounded by trees exceeding 70 ft. in height, it is unlikely that it will be useful in future. Its recovery, however, is now complete.
The station, monumented in 1891 when Benjamin Harrison was President, and last reported in 1935, was found today in good condition.
The station is now the property of Mr. Gerald F. Zecher, at #22 North Street, Lexington, MA and sits near the top of an extensive ledge outcrop above the northerly side of his house. It was searched for with his kind permission. The station lies about 5 ft. (NW) from the apparent highest point of the ledge outcrop.
The ledge was found heavily covered with thickly matted roots, moss, and decomposed pine needles. Given the difficulty of clearing the ledge, the three RMs in lead were not searched for. The Mass. Highway Dept. has been asked to check on the existence of additional data for these marks, since their distance and direction appears to have beem omitted from the Description.
In the meantime, three new references were established (see photos). (1) The westerly corner of the house's chimney bears about 192 dT from the station, distant about 45 ft. (2) A 12-inch oak tree bears about 12 dT from the station, distant about 22 ft. (3) The bark of the center of the westerly trunk of a four-trunked pine tree bears about 260 dT from the station, distant about 15 ft. All distances were measured with a hand-held laser measuring tool and bearings were taken with a hand-held baseplate compass.
A small cairn (see photo) was left over the station mark, since the property owner asked that it not be blazed.

The site was visited today, without success. The mark may well be there, however, and the hunt will continue.
The apparent "highest point" of ledge was found, but was heavily covered with pine detritus and tufts of turf. I will try to get the homeowner's permission to clear off the ledge and expose the mark, which apparently dates from 1891. If it's been hanging out for 117 years, it can age a few weeks more...
