Vol. XXXX, No. 6 --- June 2003
Well, the way I see it . . .
I hope everyone recalls my letter in the April Newsletter about the AFMS/CFMS Gem Show, because by now you are either at the show or this newsletter is in your mailbox waiting for you to return home to read it. Or, you missed the letter as well as a great Gem Show and a chance to see some different things from what you have in your local area club shows, as well as the opportunity to attend some different field trip sites.
Which brings me to another subject. When was the last time you talked to your Senator or any government representative? If you are like me, you have been getting lots of letters from them lately. Strange how that happens when election time is coming up, they all want your money. Well, what better time to let them know how you feel about the way they have been managing our public lands? Let them know you believe that it is "Public Land" and meant to be used by all the public. So it is to be made accessible for our use and not closed off to access. We need access for field trips. If you are sending your money, let them know what you want them to do for you.
At this point, about all that is on my mind is that by the time you read this, I will be at the AFMS/CFMS Gem Show in Ventura and enjoying it. I also hope a lot of you will be there and thinking about putting on a Federation Show with your club and getting some good ideas to take home to your members.
Hoping to see you all at the Seaside GEMboree.

When you go to the CFMS website <http://www.cfmsinc.org>, the first page that comes into view is divided into two frames. The frame at the top of the page is a permanent navigation page. The frame at the bottom of the page is a temporary Welcome page that changes when a new page is selected.
The frame at the top of the page contains the following links:
Welcome - The Welcome page has a side bar for linking to changing events. Once a link is clicked, the Welcome page changes to the selected page. The Welcome page will have some of the following links to changing events: 2003 Forms I Current Federation Field Trips I In Memoriam I Slide n Video I etc.
About CFMS - Some of CFMS history. Bulletin Board - Current events.
The website is only as good as inputs from CFMS members. Needed .jpg Photos of events, field trips, etc. Needed Biographies of Past Presidents, and Golden Bear Awardees. Please check out club information and email addresses.
Adherance to the AFMS Code of Ethics assures compliance with most statutes and regulations governing collecting on public lands and encourages respect for private property rights and the environment. Clubs are urged to read the AFMS Code of Ethics in at least one meeting every year, to publish the Code frequently in the club newsletter, and to compel compliance on club field trips.
2. Individuals and clubs are urged to write their elected representatives and land use management agency supervisors regarding issues of rule making, legislation and enforcement affecting field collecting of minerals and fossils.
3. Individuals and clubs are urged to join and support activities of the American Lands Access Association (ALAA), a sister organization with responsibility for advancing the interests of earth science amateurs with legislatures and land use management agencies.
4. The AFMS will receive a report from ALAAA at its annual meeting.
5. The AFMS endorses the principle of multiple use of public lands as guarantee of continuing recreational opportunity.
6. Wilderness and monument designations are inconsistent with the principle of multiple use. In view of the vast amount of public land already designated as wilderness and monuments, future such designations should be minimal, taking into account the increased demand for recreational opportunities, including rockhounding, created by a growing population.
7. In furtherance of the principle of multiple use, the AFMS believes that laws, regulations and rules established by relevant governmental authorities should be designed to allow freest possible access to all public lands, coupled with minimal restrictions on the recreational collection of minerals, fossils, gemstone materials and other naturally occurring materials.
8. A right to collect minerals and fossils on public lands should be protected by statute.
9. The AFMS urges its members to work with any or all government authorities to achieve a good working relationship in order to improve the "Public Image" of recreational collectors.
(This policy was adopted by the AFMS Board of Directors in Summer of 2002.)
Because CFMS is affiliated with the American Federation of Mineralogical Societies, our members observe the following principles:
(Clubs are urged to publish this Code in their club newsletters and to compel compliance on club field trips.)
Partnering with Local Museums
In the March 2003 issue of Rock & Gem magazine, Steve Voynick had a great article entitled "Wanted: Paleo Volunteers: Great Opportunities for Fossil Fanatics." In it, he describes museum-sponsored programs that will train you in the basics of paleontology, fossil hunting and preparation. In an era of budget cuts, museums are forging links with volunteers that result in a win-win situation: volunteers get to learn about fossils from professionals and gain museumsponsored certification in field excavation and laboratory fossil preparation, and professionals gain invaluable assistance in collecting fossils from the field and in documenting, preserving, and curating collections. This looks like it would be a great opportunity for your older junior members to forge links with professionals and to "try out" a potential career as a paleontologist.
I encourage your junior leaders to get a copy of this issue of Rock & Gem and Voynick's article. He closes with a listing of museums from across the U.S. that sponsor volunteer programs, complete with mailing and web addresses for learning more about such opportunities. That list includes eight from our own home state:
Anza-Borrego Desert State Park, 200 Palm Canyon Drive, Borrego Springs, CA 92004; www.anzaborrego.statepark.org
Buena Vista Museum of Natural History, 2018 Chester Avenue, Bakersfield, CA 93301; www.sharktoothhill.com
George C. Page Museum of La Brea Discoveries, 5801 Wilshire Boulevard, Los Angeles, CA 90036; www.tarpits.org
Oakland Museum of California, 1000 Oak Street, Oakland, CA 94607; www.museumca.org
Orange County Natural History Museum, 28373 Alicia Parkway, Laguna Niguel, CA 92677; www.ocnha.mus.ca.us
Raymond M. Alf Museum of Paleontology, The Webb Schools, 1175 W. Baseline Road, Claremont, CA 91711; www.alfmuseum.org
San Bernardino County Museum, 2024 Orange Tree Lane, Redlands, CA 92374; www.co.san-bernardino.ca.us/museum
San Diego Natural History Museum, P.O. Box 121390, San Diego, CA 92112; www.sdnhm.org
If you have junior members with a burning passion for paleontology, check out these and any other museums near your own home town. Opportunities like these are a sure way to give junior members a hands-on feel for what a career as a paleontologist would be like while-as always-having fun!

The following article was given as a talk at the March meeting of the Carmichael G&MS by Jennifer Thomas-Anderson who is an 11-year-old Junior Member of CGMS.
Quartz is a common mineral that occurs in many types of rocks. Pure quartz is transparent. It is made of silicon dioxide and has the chemical formula Si02. Quartz has many uses in science and industry. Quartz can be found in several forms and in all three major kinds of rocks. These are known as Igneous, Metamorphic and Sedimentary.
Except for Feldspar, it is the most common rock forming material in the earth's continental crust.
Quartz is also one of the hardest minerals. Only Beryl, Spinal, Topaz, Corundum and Diamond are among the few harder minerals. Erosion does not wear away Quartz as rapidly as it wears away most other rock minerals.
There are many varieties of Quartz. Geologists often divide them into two general groups. Crystalline forms of Quartz included six-sided prismlike crystals and massive granular clumps in which the individual grains of Quartz can be seen. Rock Crystalline Quartz that occurs as colorless, transparent crystals. Granular forms of coarse crystalline Quartz include Rose Quartz and Milky Quartz, the colored granular forms.
Color change is due to trace elements that are not essentual constituents of the mineral species. First important shapes of crystals were made (identified) by Neil Stensen, a Danish Physician better known by his Latinized name Nicholous Steno. In 1669, Steno results were variable because relative sizes and shapes of the faces differ from sample to sample. Steno discovered the angle between any given pair of faces is always the same. This is known as the Law of Constancy of interfacial angles.
A few mineral species include varieties that are so common that they were given names. Color is the most common basis for naming diverse varieties; Rose Quartz, Amethyst, Smokey Quartz, Citrine and Rock Crystal. The colors of these gemstones are due to trace elements.
Minerals form whenever and wherever the appropriate temperature, pressure and chemical environment exist for a long enough period of time for the constituate atoms to become ordered in a crystalline structure. Some minerals form only within very limited ranges of temperature and pressure. Others from a broad range of conditions. Most minerals are formed as a result of one of the following processes.
When the conditions of formations are such that growth is relatively slow and not physically constrained by grains of other minerals, well developed crystals often result. These specimens are prized by collectors. If growth is impeded, only a few or none of the crystal faces will develop. The resulting grain shapes are termed subhedral or anhedral. Most rocks are made up largely of both. Lengthwise striated prisms with cross section that resemble spherical triangles, electrically charges on heating and cooling.
Large crystals indicate slow cooling and slow growth. Small crystals indicate rapid cooling and that large crystals did not have time to grow.
Going back to nature with camping means leaving behind some familiar conveniences. It means using some unfamiliar procedures. To make sure a camping trip is an enjoyable experience, be sure to follow safety rules.
Some tents are manufactured from cotton, which is a flammable substance. Sometimes the fabric treatment used to make tents waterproof actually increases the flammability, according to the U.S. Consumer Product Safety Commission. Buy a tent that is flame retardant. Remember "flame retardant" doesn't mean fireproof. A flying ember from a fire can land on a tent and ignite it in seconds.
There are other things that can burn-- such as sleeping bags, clothing and people. A tent should be sited upwind from any campfire or outside cooking or lighting devices. Create a three-foot clearing around the tent. Use only battery-operated lights near or inside it. Always refuel any heat-producing appliance, such as lanterns and stoves, outside a tent. Always store flammable liquids, such as gasoline, outside a tent.
DON'T COOK INSIDE A TENT!
When preparing a campfire, a site should be selected that is away from grass, trees and tents. An area ten feet around the campfire should be cleared of ground litter, twigs, leaves and organic material, down to the bare soil. The site should also be downwind from the sleeping area to prevent catching a tent or sleeping bag on fire from a spark or ember. Rocks should be placed directly aroung the campfire pit.
If weather conditions are especially dry and you don't really need a fire for cooking, don't build one. A small spark is all it takes to ignite dry grass and leaves. Be sure to pay close attention to forest conditions and warnings from the park service. Never use gasoline to light a fire. It is extremely explosive. A fire should be lit using kindling or a lighter stick. Keep a pail of sand or water nearby in the event it is needed to control the fire or extinguish it. Wear tight-fitting cotton or wool clothing while working near the campfire. Always keep a careful eye on fires and make sure children don't play near them.
Before you go to sleep at night or if you leave the campsite for awhile, be sure to extinguish the fire. Many forest fires are started each year from unattended campfires or those that are not completely extinguished. Douse the fire with water or sand, break up the coals, add more water or sand, stir it with a stick and cover the dead embers with dirt. Make sure the fire is completely out before bedding down or leaving the campsite.
If you're using a gas or liquid fuel camp stove or lantern, follow the manufacturer's directions. Make sure all connections are tight to avoid leaks. Never check for a gas leak with a lighted match. Instead, put a little soapy water on the connections. If the mixture bubbles, gas is seeping out. Don't try to use the appliance again until it's been checked by a professional. When using a camp stove or gas lantern, always fill it before each use. Do not refuel a hot stove or lantern. Wait until it cools off. Use a funnel to fill the appliances and wipe up all fuel spills before attempting to light it again.
When traveling with a camper or recreational vehicle, use only electrically-operated or batteryoperated lights inside. Maintain all appliances in a safe working condition and check them before use. Keep a fire extinguisher on board, preferably a multi-purpose one, and mount a smoke detector inside the vehicle.
When the vehicle is traveling down the road, shut down gas to stoves and water heaters by closing the fuel supply at the gas bottle. Never operate combustion type or catalytic heaters inside closed campers or RV's. This could result in asphyxiation from either fumes or oxygen depletion.
Don't cook while the vehicle is underway. A sudden lurching of the vehicle may result in spilling cooking grease, causing a fire.
Always fuel stoves or lanterns outside campers or RVs. Accumulation of vapors from volatile fuels could cause an explosion. Avoid storing combustibles such as newspapers and grocery bags in your vehicle.

My machine is a 20 in. rotary cast iron lap. I bond slabs as thin as 0.030 in. to plywood using a mixture that is half beeswax and half paraffin wax. Then, for a 5 inch diameter slab, I use a minimum of a 3 lb. weight glued to the plywood.
In the preparation phase, to remove saw cuts and bumps from the slab, do not use 80 or 100 grit, start with 220. I usually spend 4 hours each with 220, 400, and 600 SiC grit, cleaning up carefully in between each step. I spend 8 hours on polishing and have found that tin oxide is the best for lapping. Put some in a bottle and shake it up before applying. I use carpet for polishing, securing it to the lap with contact cement and hitting it with a mallet.
When it comes time to remove the slab from the plywood, put it in the sun or under a 250 watt bulb. The heat will soften the wax and the slab can be removed.
To handle small slabs or split nodules, make a cylinder from 0.010 in. thick aluminum sheet, set it on a smooth surface, set agates face down in the bottom, add lead weight, add plaster and let harden. After the plaster column is set, remove the aluminum and cut away a bit of the plaster around the agate faces (so it wouldn"t cause drag on the lap). Put innertube around the plaster column and secure with rubber bands, then add a bumper ring. Proceed as before.

(with thanks to Leslie Neff for passing it along).
There's no egg in eggplant nor ham in hamburger, neither pine nor apple in pineapple. English muffins weren't invented in England nor French fries in France. Sweatmeats are candies while sweatbreads, which aren't sweet, are meat.
We take English for granted but if we explore its pardoxes we find that quicksand can work slowly, boxing rings are square, and a guinea pig is neither from Guinea nor is it a pig... And why is it that writers write but fingers don't fing, grocers don't groc and hammers don't ham? If the plural of tooth is teeth, why isn't the plural of booth beeth? One goose, two geese - so one moose, two meese? If teachers taught, why don't preachers praught? If a vegetarian eats vegetables, what does a humanitarian eat?...
Sometimes I think all English speakers should be committed to an asylum for the verbally insane. In what language do people recite at a play and play at a recital? Ship by truck and send cargo by ship? Have noses that run and feet that smell? Park on driveways and drive on parkways?
How can a slim chance and a fat chance be the same, while a wise man and a wise guy are opposites? How can overlook and oversee be opposites, while quite a lot and quite a few are alike? How can the weather be hot as hell one day and cold as hell on another? And where are all those people who ARE spring chickens? You have to marvel at the unique lunacy of a language in which your house can bum up as it burns down; in which you fill in a form by filling it out; and in which an alarm clock goes of by going on.
English was invented by people, not by computers, and it reflects the creativity of the human race (which, of course, isn't a race at all). That is why, when the stars are out, they are visible, but when the lights are out, they are invisible.
And why, when I wind up my watch, I start it, but when I wind up this essay, I end it!
September 6 - 13 September 7 - 20
The Earth Science Committee
The Earth Science studies at Camp Paradise, that "Getaway in the Pines" will be coming soon. This is a wonderful time to relax with friendly people who enjoy learning more about the various skills that make our hobby fun. Registrations are being taken now. More details and Information is included on the following paragraph. Click here to view the Camp Paradise Form.
In an ongoing effort to improve the Earth Science Seminars The Committee has approved some changes. In addition to our ongoing classes i.e. faceting, wire art, silver fabrication, lapidary, glass bead making and soft stone sculpture; we will feature different techniques for each session. During week one - September 6 - 13 Bob Pevahouse will conduct classes in Copper Enameling, an art ignored by many artisans; but very compatible with Precious Metal Fabrication, wire art, bead making and as an accepted art form. Dick Freisen will be holding forth with sessions in Gemstone carving, which generally entails the use of machinery to create intricate designs on preformed shapes of Gem Quality Material. The Instructors will have basic supplies available at a nominal cost.
Week two: September 14 - 20; Bural LaRue and Betty Egger will return with their very popular Silver Casting Class. Cheri George will be teaching Glass Fusion. Please Note the above classes will be available ONLY during this period. Supplies will be available from the Instructors at a nominal cost. If you wish to supply your own material PLEASE contact the Instructors.
We have, for the most part, abandoned field trips due to a lack of collecting areas and participation.
Accommodations will be assigned as received with any special needs considered, and in so far as possible dietary needs will be accommodated.
We have maintained the cost at $220 per person per week with access to all facilities and classes. Early registration is recommended to ensure acceptance due to a limit of approximately 60 participants per week.
I plan on bringing six carving workstations with me to Camp Paradise this fall. This will be an "unofficial" class and may not be listed on the camp notice. I will be supplying everything (except optivisors) for a beginner to do a first carving. There will be a limited amount of better material available for additional carvings or advanced students. Students wishing to do advanced work should consider bringing material to work on with them to the camp. I plan on being at Camp Paradise both the first and second week.
