This community and Abington, MA (where I live) were the source of most CD 134 amber T-H.E. Co. insulators known in our hobby. These were used upon fire alarm circuits in both towns. In the early 1970s I and another collector (lineman) retrieved what was left among these neat Brookfield-made insulators (probably from leftover end-of-day beer bottle glass) with about 40 or 50 known to this day in various states of condition. Without doubt there is one of these deep amber insulators somewhere within the vantage point of this photo.

The Southern Massachusetts Telephone Company also operated in Rockland (and within other southeastern MA towns). New England Telephone purchased SMT's Abington and Rockland's subscribers the latters' earlier days, so few glass insulators marked So. Mass. Tel. Co. have been located in this vicinity.
