TOWN WILL CHANGE ITS NAME DEC. 1
Northdalles Residents Petition to Have District Termed Dallesport, Report Says

     Word was received by The Sentinel the fore part of the week stating that Northdalles will be known as Dallesport after December 1.
     The official word was sent The Sentinel by Mrs. Hessie R. Mann, Northdalles postmistress, who said: “Please be advised that the name of the post office here at Northdalles will be changed to Dallesport effective December 1.”
     The short letter aroused considerable interest and a Sentinel staff member investigated further to find the how and why of the change.  It was learned that a development which is now under way along the flats across the Columbia from The Dalles would point toward the time when an orderly laid out city would be thriving there.
     The man who is caring for the development recently met with those interested and suggested a change in name.  He went further and suggested Dallesport to replace the more widely known Northdalles.
     The idea seemed to catch on and the suggestion was released in a quiet fashion.  It was Mrs. Mann, the postmistress, who receives the actual credit for the change, The Sentinel learned.  She circulated the petition for a change.  A percentage, thought to be 60, of the patrons of the post office must acquiesce if the name is to be changed.  The names were obtained with little effort a few weeks ago and the petition forwarded to the federal authorities.
     The answer back was favorable and Mrs. Mann sent out her official announcements this week.  The area was originally known as Grand Dalles, later as Northdalles, and after December 1 will appear on the official records as Dallesport.
