This friction may be of two kinds—the friction
of metal on metal, due to the failure of the oil
to preserve a lubricating film between the bear­

internal, molecular friction of the lubricant
Too heavy an oil, or an oil lacking in "oiliness”
— the quality that makes it cling to the bearings
while at the same time offering a minimum of
internal or fluid friction—constitutes a direct
drain on the available horsepower of your

Mad» from carefully selected crudes and scientifically
refined by our patented high-vacuum process, Zerolene
has great “oiliness.” It clings to bearing surfaces, while
offering in itself a minimum of frictional resistance to

OBITUARY
Ida Mercy Martiny, daughter of
Mr. and Mis. W. N. Vaughn, was
born July 15, 1860, in .be old log
cabin on the Donation Land Claim
of her parents, on bleb claim the
present town of Idaville, in Tilla-
mook County, ls now situated. She
died July 27, 1922, being then 62
years and 12 days old. Her mother
was the first white child born on the
Clatsop Plains, South of Astoria,
and she herself was the first white
£hild born and still living lh Tllla-
iiook County. ,
She came of the old, sturdy pio­
neer stock, and of parents whose
opeuhearted hospitality and liber­
ality were widely known throughout
the country.
She was married to Edward
Walker in the year 1891 at Tilla­
mook, Oiegon, und to this union
was born one daughter, Harriett,
on December 19, 1893. They later
moved to a farm at Oretown in this
county, where they resided for sev­
eral years, ofter hlch they returned
o Tillamook and Mr. Walker in­
gaged in busin«-s as a harness
maker. Mr. Walker died in the win­
ter of 1903. Shortly after his death
rhe purchased the property Hi Tilla­
mook City which has ever since been
er home.
In the year 1908 she muiiied Mr.
David Martiny. who is now the
owner and operator of a garage In
. ilamook City, and who, together
with her daughter Harriett, survive
her.
Beside her busband and daughter
she leaves four brothers and seven
sisters: Amos Vaughn, Lydia Hos­
