Editor's Notes

[Letterhead: The Wyoming] Writes from Scranton for TAE's aid in securing a contract for the Gamewell Co. fire alarm system worth $10,000 to $13,000; in competition with the Richmond Fire Alarm Co. of Richmond, Ind.; encloses pages from Richmond Co. catalog and is certain TAE will see the flaws in their systems; asks TAE to send an autograph letter giving his expert opinion and answering four questions: 1) Is the open or closed circuit system the correct plan for a municipal fire alarm system and on what do you base your opinion? 2) Do you know of a reliable non-interfering system and is the non-interfering feature of value? 3) Is a gravity battery suitable for use on a line normally open and only closed when giving signals at extremely long intervals? Why or why not? 3) Which is the better system Richmond's or Gamewell's; notes that Gamewell is offering the same system being constructed in Orange.
