TITLE: GUADALUPE Large Increase Made in Mercury Output AUTHOR: ESTHER WALKER PUBLISHER:San Jose Evening News, January 11, 1944
That 64-foot long furnace the Laco Mining company has installed at Guadalupe mine cost the company's five partners about $90,000 but it's paying off in quicksilver.
Production since its installation three and a half weeks ago has jumped from seven and a half tons of ore processed a day to 80 tons which "isn't hay," what with quicksilver bringing $188 for a 76-pound flask.
It resembles a gigantic corn popper, that quicksilver furnace. Into one end goes the quicksilver-bearing cinnabar in reddish brown chunks, to be rattled around inside the huge rotating brick-lined, oil-burning furnace where it pops and crackles as it's roasted in the intense heat, throwing off quicksilver vapor into an adjoining condensing system and, when thoroughly burned out, dropping down into an underground hopper where it's later hauled away in man-propelled box-cars as slag, exhausted of its metal content but extremely useful in reinforcing the county's dirt roads.
Guadalupe employees don't fool around with that slag when it first leaves the furnace. It's been cooked to a sizzling 1100 degrees Fahrenheit and it's red-hot.
The quicksilver vapor, on the other hand, is in for a sudden cooling after it's blown out of the furnace. A fan heads it into a cast-iron condensing system; the temperature is reduced below that 358 degree Fahrenheit level at which quicksilver vaporizes and, presto, the Laco company has produced one of this country's most strategic war materials.
Not a drop of the only liquid metal known to man is wasted. Muddy residue from the condensing system is kneaded with a hoe and globules of mercury scamper away to slide down a pipe into a special container used in filling the steel flasks in which it is shipped. Flasks Exchanged
Even the empty flasks are valuable. They're interchanged by the various mining companies, much as railroad companies utilize one another's box cars.
At Guadalupe mine this morning there were the mine's own steel flasks, marked with a green "L." Others marked with red, yellow and other distinctive paint were from the Almaden mine, New Idria mine near Hollister and half a dozen other scattered quicksilver mines, and all were headed for Guadalupe's two main shipping points, San Francisco and Fresno.
Fifth in total production among America's some 50 operating quicksilver mines - the New Almaden, [part of article is missing]

Uses of that Guadalupe quick-silver, scientifically known as mercury, have expanded tremendously during the war.
It's valuable as a fulminate for detonation of explosives where high dependability is required. It's the basis for DuPont's famous mercurial paint used on ships as a [remainder of article is missing]
HEADQUARTERS FOR PAPER DRIVE CHOSEN
Storage headquarters for San Jose's salvage paper drive today had been definitely decided, following permission from the city council for the sponsoring Lions club to erect a tent north of the USO hut.
Approval of the headquarters site came from council members at their meeting last night after Cliff Gottwalls, chairman of the Lions committee on procurement of depots and storage facilities, explained that a central location was necessary to direct details of baling and assembling the city's wastepaper donations. City Manager Clarence E. Goodwin explained that the site had previously been approved by the Merchants association of San Jose.
Gottwalls asked also that the period from January 26 to February 9 be publicly proclaimed as San Jose's paper drive.
Plans for the drive call for a fanfare of publicity, including a downtown luncheon of drive leaders and street stunts by entertainers on the opening day, General Chairman K. W. Van Gundy has announced.
San Joseans are asked to save newspapers, magazines, cardboard, including cartons and packing boxes and general miscellaneous scrap paper. Wax paper will not be accepted.
INCOME TAX OFFICE IS BUSY PLACE
San Jose taxpayers are already appearing in large numbers at the local revenue office in the post office building to receive assistance in the preparation and filing of their 1943 income tax returns, and are apparently taking seriously the frequently published advice of the department that returns should be filed as early as possible, Remo N. Cipolla, division chief, stated today.
Since it is mandatory that subject employers give employees forms W-2 and or V-2, statement of earnings for the calendar year of 1943, on or before January 31, the local office particularly requests that this be done as soon as possible since the information together with income and victory tax withheld, is essential to employees in the correct preparation of their returns.
A generous supply of most of the forms required by taxpayers, accountants and lawyers has been received and it is believed that the office will be able to supply all requested. However, taxpayers should use as far as possible forms received [remainder of article is cut off and missing].

A downhill grade make the going fairly easy once the cars are loaded and started down the incline and the two miners usually "hop on and ride".
