PRESIDENT'S MESSAGE

Did you ever walk under an old bridge or into an old house and look up and see the sills and all rotted out and falling down? Tlmt's what this dub looks like. Today there axe five offices vacant One was never filled and four officers have or do not attend meetings. I can't fault those I can understand that circumstances could cause you to n~t be able to do the job ~U1y longer. I am sorry ~hmgs turned out that way and I thank you for giving It a try.

I looked through the roster and I don't know 75% of the members. I wonder why. I am sure it is as much my fault as your's. Most of those lhat I do know are old members. Some have decided that they have done enough in their time. Some can't remember their names. any longer and think they are not able to help (I am 111 that group), and the rest are just riders.

I, am going to t:t~ around asldng some of you to help. ;Some of these Jobs don't take much time; just a few ilours two or thrr--e times a month. Some will say they don't know how, but that's a pretty poor excuse. You hav.c been working, some years for a living and this is eaSIer than that. When I ask you how about giving me a hand, someone will give you instructions on wllat to do and help you for a while. This is too good a club to just rot and fall to pieces.

Some of you might not have noticed that the last two Petrographs did not have a President's Message in it Th~t's one of my duties, but I got to running around dUl1ng the summer and didn't get it done. ~I1lat's my "excuse". Remember what an excuse is (the skin of a reason stuffed with lies). Sadie and I tw.d a summer and you did too. Now it's time to back to wodc

Don't forget the spagheAti feed next month at the general meeting. Christmas is almost and

show is coming up before we know it There will be jobs available in all of these happenings. Be a volunteer ~- ask someone what you can do.

See you at the shop and around here and there. Elmer Snyder

Edna Antunovich has picked up the job. However, Edna is also the Junior Mentor and does the printing for the club, so she'll be needing lots of assistance. Good luck, Edna.

The 1991 ~Ulnual show could be off to a rip~roarin' start. It could that is, except for one little problem -- we don't have a Chairperson. If you are interested or if you know someone who would be interested in doing this slight las-ic (ha, l1a), contact Joe Hammond sometime this month.

The fem~like and branch effects of trees and grass come from fart that these tiny canals branch out from a common center. Technically, Montana known as "Dendritic" agate, and the moss axe called "dendrites". It is the third hardest stone. There can never be two pieces alike even though cut from the same stonc.

A management plan and environmental assessment for the Clear Creek area on the San Benito County-Fresno

has been prepared by the BLM.

'n1cm more than 100 semi-precious gemstones ,md rdnerals in the area. BLM proposes to withdraw from commercial private mining six miles of Clear Creek Canyon, the San Benito Mountain Natural Area, and other slA'X:ific collecting sites.

CollCl.;tible materials include jadeite, cinnabar, tremolite, melanite. topax-olite, barkevikite,

clinochlore, vesuvianite, artinite, natrolite, nepnmite, and benitoite.

Some minerals, such as benitoite, are extremely rare and the Cleax Creek area is practk:ally the only in the where can be found.

HINTS ON SETTING UP YOUR DISPLAY CASES (Hy Grader) ~ ~~~, ~~~<~

Be sure your liner is clean, pressed, and of a neutral color that won't detract from your cabs or specimens. DON't CROWD your case. A crowded case is a sure sign of a rank amateur. Wash your specimens at least two or three days before setting up. as the heat from the lights can cause moisture to steam up the inside of the glass.

A soft thin glove worn when placing specimens in your case will prevent finger marks on polished surfaces. Last-minute lint or dust can be removed using a piece of scotch tape on the end of your finger.

Place your best piece as the center of interest. Never place your larger pieces in front. Use risers, if nccessary. If you are displaying silver pieces, conceal a camphor bar in your case. This delays the tarnish time. Be sure to place it in a small dish, as it bleeds.

Your labels should be typed and spelling checked. Your name should be in your case.

A silicone cloth or paper used just as stones are placed in a case gives a last-minute brilliance.

SHOP HINTS (The Palomar Gem)

On a drum sander that is well worn, wet the paper and then turn on the machine. Use a chunk of obsidian to refresh the sander.

Do not tumble marcasite, as it will almost always come out irregular and pitted.

BurrON MOUNTING (Color Country Chips)

A simple button mounting can be made by flattening a bell cap and cementing it to a flat back: of a cab or baroque to use as a button.

WIND CHIMES (GOlden . SpIke News)

The best material for wirld chimes is solid Brazilian agate, Indi~Jl black skin agate, or India red~green moss agate. Picture jasper is also very good. Slice material 1/8" thick. DO NOT POLISH, as it has a deadening effect. l)!J not use slabs with cracL,>.

\Vhen cutting porous rocks under hardness of 5, soak materials in water for a 'week or more and you'll have no problem with stone soaking up the oil.

DOUBLET OR TRIPLET? (pegmatite) . .. ..

To detect a doublet or a triplet, hold the stone 'with tongs in a white porcelain container of water. When viewed from the direction of the girdle, the various layers are obvious.

TO CLEAN SILVER (Rocky<Review)·· .

Add a haJ1dful each of salt and soda to water in an aluminum bucket. Add silver. In a few minutes it's like new. You have only a plastic bucket? Add a piece of aluminum foil.

One way to polish material which will undercut, such as sagenite, moss agate, plume, porou..s wood, and wood with iron, is to nrst completely cover the slices with water in a flat pan with some detergent 311d shake of Comet, elevating the slice on a small object such ns a ja.r ring.

You start the rocks in lukewarm water, gradually bringing to a slow boil about 10 minutes, keeping the slices well covered with water at all times.
