O o About 4J miles farther east, near the south end of Lake Quinsigamond, just east of the corner of Lake Avenue and Harrington Street, is a narrow sinu- ous gravel ridge that ex- tends south to the electric railway on Grafton Street and thence through the woods to the head of Dorothy Pond. In some places this ridge is 30 to 40 feet high; in others it spreads out indefinitely, blending with the swells of the morainal topog- raphy. About 3| miles north- east of North Grafton a sinuous ridge of gravel runs southward from the electric railway 450 to 550 yards and then branches into three distinct ridges 10 to 30 feet in height, which continue south about half a mile and merge into the morainal deposit at the head of Miscoe Brook valley. The easternmost of these ridges swings across the north-south road and extends up a slope 20 to 30 feet in height onto the south end of the morainal ridge east of the road. About 2| miles still far- ther east, another system of e s k e r s extends from the southern part of Westboro to Westboro Reservoir. Here there is an interesting association of eskers with drumlins (fig. 8). The foot of the east slope of the finely formed drumlin iust south o 'So.
