Statements to the effect that the station may have been named for Ivan Kesterson, connected with a local sawmill enterprise, are wrong. In June, 1948, Irving E. Kesterson wrote from Atherton, California, ruling out any connection between the station name and that of his brother Ivan. The two Kestersons were at one time associated in the operation of a sawmill near Ivan station. Irving Kesterson says that he bought the mill in 1917 and his brother Ivan joined the enterprise in 1918. The station had been named some years before. Ivan post office was established November 18, 1926, with Andrew J. Hanan postmaster. The name of the office was changed to Worden in March, 1930. The office was doubtless moved several miles to Worden at that time. There had been a post office at Worden some years previously.
IVISON, Lane County. Ivison was a post office on Wildcat Creek west of Eugene and a few miles east of Walton. The office was established March 3, 1893, with Isaac S. Day first postmaster. Thomas T. McGlynn was appointed postmaster May 11, 1909. The office was discontinued September 15, 1909, with mail to Elmira. In February, 1947, Mrs. C. A. Stephens of Eugene wrote the compiler that she was the daughter of Isaac Day, the first postmaster, and at the time the office was established, Day was asked to submit a name for the place. There was a school. teacher boarding at the Day home, and the teacher was given the selection of the name, and she chose Ivison. She was with the impression that Day's given name was Ivison and not Isaac, and she selected Ivison in supposed compliment to Day. By the time the error became apparent, postal authorities had established the office with the name Ivison.
Ivy, Clatsop County. This railroad station east of Astoria was so named because of a heavy growth of ivy over the remains of a building south of the track.
IZEE, Grant County. In 1927 J. E. Snow of Dayville told the compiler that this post office was so oddly named because a local stockman, M. N. Bonham, used the letters I Z for his cattle brand. Postal authorities inform the compiler that Izee post office was established November 6, 1889, with Carlos W. Bonham first postmaster.
Jack CREEK, Klamath County. Jack Creek is in the northeast part of the county. It heads east of Walker Mountain and flows generally southward to Klamath Marsh and Williamson River. It was originally Jackass Creek. but the passage of time has shortened the name. Dr. Thomas Condon on July 31, 1877, wrote while on a trip to Fossil Lake: "Finally we reached water (at Jackass Gulch), where we camped." See Thomas Condon, by Ellen Condon McCornack, page 199. Despite the fact that there are more than a dozen Jack creeks in Oregon, it is improbable that the original name of Jack Creek will be revived.
JACKKNIFE CANYON, Sherman County. Mrs. Lulu D. Crandall of The Dalles told the compiler that her father, Z. Donnell, named Jackknife Canyon because of the circumstances connected with losing a jack knife near the canyon in the fall of a year in the late '60s. He found the knife the following spring and named the canyon on that account.
JACKPOT MEADOW, Clackamas County. Jackpot Meadow is about ten miles south of Mount Hood and drains into Salmon River. It was named because after periods of wet weather it was easy to get into and hard to get out of.
Jacks BRIDGE, Clackamas and Marion counties. Jacks Bridge is on Butte Creek about a mile southwest of Marquam. The name commemo who was the
