A trolley line also is seen here serving within this Maine community. On the left is a pole line with an "add-on" pole top wood bracket (sidepin) construction that I believe was for local fire alarm telegraph service. The latter were typically placed upon pole tops through around 1910 at least here in New England. Poletop fire alarm circuits installed as such physically and electrically protected them from the mazes and clutter of potentially falling electric and telephone wires.... if otherwise strung beneath. Gamewell and many others installed such lines atop poles as standard practice owing to the fact that fire alarm calls via boxes throughout communities served were of the utmost, vital and often...the only...means of immediate emergency connection in those days since telephones were not yet all that commonplace (albeit still a bit expensive). When phone service became much more affordable and thanks to enclosed-paired-cable (lead sheathed) and standardized local electric distribution construction, many pole lines were more reliably (safely) rebuilt commencing in the teens with fire alarm circuits typically re-lined just above the then-new telephone cables with electric service above them.
