EACH CLUB-EACH YEAR
-ONE ROCKHOUND

by Margaret Pearson,
AFMS E.C.E.Y.O.R. Chair

The following rockhounds are being recognized for their outstanding service by the AFMS through its program: EACH CLUB-EACH YEAR- ONE ROCKHOUND. The names of rockhounds honored by their fellow members for their contributions to their club and the hobby are in no particular order. The AFMS congratulates these hardworking club members!

MARGARET'S MUSINGS

by Margaret Heinek
President, AFMS

So much has happened, weather wise this winter and spring, especially in the Dakotas and lately in Canada. I sincerely hope all of our members are O.K. My heart goes out to all that have lost their homes to the floods. Here in Indiana and Michigan we have had "interesting" weather, snow in late April and early May! I am looking forward to a good "summer".
The show committee in Jackson, Miss. promises us real good weather. Have you made your plans for the AFMS 50th Anniversary Celebration? The information on the Convention, to be held October 13-19, 1997, has been sent, and the committees have been busy with the plans. If you have not received your copy of the forms, let someone know, or write to Mary Jane Boutwell at 367 Virlillia Rd, Canton, Miss, 39046-9001 and ask for the information, or contact her E-Mail at vboutwel@mail.netdoor.com.
Have you thought about items you would be willing to donate to Charles Leach for the Endowment Fund Auction? Glenn Lee, Ways and Means Chairman, has asked for three good items from each Federation (they will take more!). As of April 20th, Charles had received 3 items, all good ones. Charlie always has many items that are worth bidding on at his auction at the AFMS Federation's conventions, so plan on being there with your extra money.
For those that send me your bulletins, Thank you. There are so many good ideas in them. My husband (Bob) and I read them, then they are passed down to our club editor, and then taken to the club meetings for the members, finally they are taken to our shows for any of our attendees to take home. Talk about re-cycling!

MEMORIES -
SILVER ANNIVERSARY TREASURES

by June Culp Zeitner
Chair, Silver Anniversary Cabochons

In all, 1,309 cabochons of American gem materials were collected to present to the Smithsonian where the AFMS Silver Anniversary party was held. These were all cut by American lapidaries.
The amazing array of well-cut cabs of wonderful gem materials ranged in size from a 5 carat moonstone to a half-pound agate. The Midwest Federation sent the most cabs, followed by the Northwest Federation. At the time of the party, no cabs had been received from Delaware or Hawaii. The Idaho County club sent more than any other club. Slides of the cabochon decorated cake and some of the stones will be shown at the Golden Anniversary show at Jackson, Mississippi, October 17-19.
Here is a list of the cabs used to decorate the cake. One was chosen to represent each state sending cabs. They were selected for size, color, beauty, workmanship, variety and quality as well as being a true example of the state's gemstones. They were not necessarily the rarest or the most valuable. They made a stunning display!

IN THE SPOTLIGHT -

by Betty M. James

The American Federation of Mineralogical Societies celebrates its 25th Anniversary at the Smithsonian Institution in 1972. A tiara was fashioned for the occasion by Henry O'Sullivan. It had a prominent "76" topped with a quartz stone cut to resemble the flame of the Statue of Liberty. The gold vermeil tiara featured state stones of many shapes, colors, and sizes, including a diamond from Arkansas, donated by dealers and friends.
Mr. O'Sullivan presented this tiara to June Culp Zeitner in a ceremony at the White House Rose Garden. Among those present were First Lady Betty Ford, the Mayor of Washington, and an honor guard. Ms. Zeitner received the cup in appreciation for her work in getting 45 states to adopt official stones. Some pictures of the occasion include a reproduction of Mt. Rushmore in the background. Ms. Zeitner continues to work with the states that have not yet adopted official stones. She hopes there will be at least 47 such official state stones by October, when the 50th Anniversary of the American Federation is celebrated in Jackson, Mississippi.
June designed a matching gem collar of gold vermeil set with the full variety of colored state stones. The collar was crafted by Wayne Olson (deceased) who was then a member of Ms. Zeitner's home club. Although June has worn the tiara several times, even on field trips, she has never worn the collar.
Many rockhound clubs around the country asked for pictures and information about the tiara and collar. In response to this tremendous interest, June put together slides and developed a program to be shared with clubs. The tiara and collar will have their own special exhibit at the joint AFMS-EFMLS Show Oct. 17-19 in Jackson, Mississippi. At the show, June will give a full and complete history of the items and show the slide program.
June Culp Zeitner was a member of the editorial staff of Lapidary Journal for 38 years and published 9 books during that time. From her experiences, she can relate anecdote after anecdote of shows, field trips, and club activities. Her work as a writer and speaker has been a major factor in the advancement of our hobby. Don't miss your opportunity to hear this outstanding rockhound and see the historic tiara and collar!

OXALIC ACID LIGHTENS TIGER EYE as well as cleaning iron oxide off quartz and the like. Use 1 tablespoon per cup of water. OXALIC ACID IS A POISON, so do NOT use cooking utensils if you decide to boil to speed up the reaction. A bit of aluminum foil or nail will speed things up. Green water means it's working. It's best to work with a finished, but unpolished cab. Petrograph via Breccia et. al.
It is reported by several publications that Apache Tear Caves in Superior, AZ is now closed to collectors and is being commercially mined for perlite.

EDITORIAL
OLDER AND SLOWER?

by Mel Albright

Are you all getting older and slower? No, not you individuals. Your club! Are you getting "sot" in your ways? Do you ever venture new things? Are you running out of members? Are all your members retired or nearly so? Do you sit around and wonder where the new members are and why they drop out? If you answered yes to many of the above, it's time to stir the pot.
Through e-mail comments and swap bulletins, I realize that many of our clubs are "fading into the sunset". They are static and rarely get new members and seldom keep those they get. What kind of way is that to run an organization?
The big question is "Why" Why are we not getting new, young members? Why can't we keep those we get? Why are we happy with a fading club?
First - let's consider today's young family. First, we must recognize that they are busy, busy, busy and are scheduled day and night for family, child, church, and civic activities. So, if we want their attention, we must offer something unique. Many clubs do this - they have lots of field trips, they have lessons, they have special youth programs, they talk at schools and to the scouts and who-ever else they can. They recognize that kids love rocks and fossils and are the key to their parents attention. Second - and this is VERY important - we must plan our activities WAY ahead of time, so that we can get on the young family's schedule. If there's an exciting field trip announced for 3 weeks from now, that's too late. They are already scheduled for that Saturday. Try 6 or 8 weeks or more. Then, we must stick to our schedule. They'll soon drop out if they plan a club activity and then we change it at the last minute. Your old members may be worn out on a collecting site, but the new ones surely are not!
Now, what do most new folks find interesting? HOLD ON! It is NOT shows, swaps, contests, show cases, rock shops and the like. It is field trips. It is show and tell - touch and feel. It is teach me how. It is hands-on workshops. It is "gee whiz" like dinosaurs, and sea fossils and beautiful minerals and interesting crystals and glowing fluorescents and plate tectonics and "why" things are as they are. And - how rockhounds fight pollution!! Your club better be an active environmental protector. (Read the AFMS field trip rules) Just watch the places where non-members stop and spend time at a show and the places they leave soon. AND it is variety. If every meeting is just like the last meeting, they'll soon disappear.
Maybe you don't agree with everything I've said. Fair enough. BUT, please take a close, critical look at what your club is doing and how they are doing it. If need be, I hope you find ways to liven things up and keep the hobby glowing and growing in your part of the world. This is a great hobby and a wonderful, unending, fascinating education! AND IT IS FUN!!!!!

My face in the mirror isn't wrinkled or drawn,
My house is not dusty, the cobwebs are gone.
My garden looks lovely and so does my lawn.
I think I shall never put my glasses back on.

SAFETY-
SNAKES!!!

Mel Albright - AFMS Safety Chair

I. SNAKE BITE!!!!

RULE NUMBER 1: DO NOT PANIC! Medical records indicate that the odds are that you have NOT received a fatal bite. Also, snake venom is a relatively slow acting material. You have two to six hours to get to help. Also, strenuous physical action will make the venom act faster!
RULE NO. 2. DON'T! Our first impulse is to do something - quick - give first aid. You should not. No tourniquets. No compresses. No cuts into the bite. No medicine or stimulants like alcohol. No sucking the venom out - it may actually cause more harm. No elevation of the affected area.
RULE NO. 3. DO! Transport the patient immediately to a medical center for care. Walking is OK if no severe symptoms have appeared and is faster than carrying. Expect swelling and remove anything that constricts the area around the bite - shoes, rings, clothing, whatever. Rinse and disinfect the wound while transporting if over an hour is involved. Apply a cool, moist dressing to slow swelling. If there are signs of shock, elevate the patient's feet about a foot. Try to identify the snake, but don't risk another bite trying to do so.
II. BACKGROUND
The best way to treat snake bite is to prevent it. Almost every bite occurs because the snake feels threatened by the person. Usually snakes are shy and will leave if given a chance. So, leave them alone!
Let the snake know you are coming. Walk "heavy" so they'll feel the vibrations. If you encounter one, (and jumped up instead of away) stay calm, back off, and do NOT threaten it. A stick or a tool or rocks are a BAD idea. Don't go barefoot in your camp area. Don't turn over rocks or brush with your hands - use a tool and look first even then. Remember, snakes often have company (I ran into a nest while plowing that had 17 rattlesnakes come out and more were in the den hole!). Do not put your hands or feet anywhere without looking first - particularly around rocks! Wear boots and long pants while in snake country.
There are 4 poisonous US snake families. Copperheads and cottonmouths are the most dangerous because they are more likely to bite. A copperhead is 2-5 feet long, copper, orange or pink tinged, has bold reddish brown crossbands on the back midline. The cottonmouth (water moccasin) is 18 inches to 6 feet long, has a broad head, is olive, brown or black, patternless with crossbands, and has a white mouth interior.
Coral snakes are not very dangerous and are mild natured. They look similar to a lot of other snakes with bright red, yellow and black bands. Remember "red touch yellow - kill a fellow; red touch black, venom lack."
Rattlesnakes come in several varieties. They are, of course, identified by their rattles. But, they do NOT always rattle before striking. The 3 most dangerous are: 1. Eastern diamondback with dark brown or black diamonds outlined by a row of cream or yellow scales and 2 to 8 feet long. 2. Western diamondback with brown diamonds on the back and sides, peppered with dark spots, and 2 1/2 to 8 feet long. 3. The Mojave rattlesnake has well-defined gray to brown diamonds, ovals or hexagons with light edges down its back and a tail with contrasting light and dark rings. Other rattlesnakes include the speckled, and the timber.
For comparison of the relative risks from bites - remember first that the bigger the snake, the more dangerous the bite. As to venom, here's a list showing relative danger - (snake name, milligrams of venom injected by a typical bite and lethal human dose from the venom) Eastern coral snake, 1-15 mg., 2-4 mg.; copperhead, 40-70 mg., 100 mg.; cottonmouth, 100-150 mg., 125 mg.; Eastern diamondback, 400-700 mg., 100 mg.; Western diamondback, 200-200 mg., 100 mg.; timber rattler, 100-150 mg., 75 mg.; Mojave rattler, 50-90 mg., 15 mg.
If you are traveling out of the country or just want more information, check the references.
NON-POISONOUS SNAKES BITE, TOO. If they do, there is danger of infection and tissue damage. Their bites should receive disinfection and professional care if they don't heal rapidly.

PYRITE PRESERVATION

by Sally Shelton*
Director,
Collections Care and Conservation,
San Diego Natural History Museum


Some of the most popular specimens for amateur collectors are pyrite. Often, these specimens deteriorate with time and become unattractive. The natural reaction is to ask "What do I do to clean this up and make it pretty again?" Unfortunately, curing the pyrite "disease" is not a matter of a simple polish job.
Pyrite "disease" is a misnomer, though, like Byne's "disease" in marine mollusk shells, there have been misguided attempts to link it with bacteria. It is a humidity-driven oxidation of pyrite that affects the microcrystalline or framboidal forms far more that it does the large crystals. The damage is preventable but irreversible once it has happened. DO NOT USE ANTIFREEZE<!> Your informant got it all wrong. It is possible to clean the reaction products off a the surface of a specimen using a "very" specific procedure developed by Lorraine Cornish and Adrian Doyle at The Natural History Museum, but this uses ethanolamine thioglycollate in a closed chamber. It is not something you do casually with no training, as removing the specimen at the precise time is necessary to prevent its destruction. The only way to slow the oxidation is to lower the relative humidity. If the reaction has not started, keep it at 45% or lower; if it has, get it to 30% or lower. Desiccants will work -IF- you know how to use them. It's not a matter of throwing silica gel into a case and walking away. Anoxic enclosures also help a lot, but, again, this is not something to do casually.
DO NOT SEAL THE SURFACES WITH ANYTHING. If you have an active reaction, coatings will not only not stop it, they may well
make it worse by forcing larger areas to spall. DO NOT REFER TO OUTDATED LITERATURE. There is some amazing garbage out there about pyrite disease. The best work on this is done by Frank Howie, Rob Waller at the Canadian Museum of Nature (who has done the best work on the specific mineralogy of the reaction) and Cornish and Doyle.
So my advice is: 1. If it ain't broke, don't fix it. If you don't have problems, don't do anything except keep an eye on things. 2. If you can't keep the RH below 45% and you think you may have problems, start with a preventive approach. There are published descriptions of macro- and micro-climate control for collections in storage. Museums have the directions for making anoxic enclosures and some advice on using and reconditioning desiccants For a large collection, you may wish to consider installing climate-control equipment for an entire case or cases; again, there are references for this. 3. If you know you have a problem, the first step is to remove the specimen from its storage environment to a work area. Brush away and discard the dry powdery reaction product. (That's a DRY, soft brush). You may not wish to do anything more other than rehousing at this point. The Cornish/Doyle method is not for the untrained, and often not for the trained. There is no magic chemical or technique that will make the damage go away. There is no disease to be cured. Low RH is the answer. 4. If you have a collection of known reactive specimens, go ahead and make anoxic film enclosures anyway even if you've slowed the reaction (it never stops). Reason: The reaction liberates sulfuric acid that can damage other specimens and storage materials. And, encapsulate (NOT laminate) the specimen labels so that they are not in contact directly with the specimen. (Yes, there are encapsulation directions, too.)
Less really is more.
I strongly recommend that you get a copy of "The Care and Conservation of Geological Material: Minerals, Rocks, Meteorites and Lunar Finds", edited by Frank Howie of The Natural History Museum (London) and published by Butterworths. To find out more: Chris Collins of the Geological Conservation Unit, Sedgwick Museum, Cambridge University has started a newsletter for this subject. For more information, you can contact him at the GCU, Madingley Rise, Madingley Road, Cambridge CB3 0EZ, UK, or at cjc1001@esc.cam.ac.uk.

PORCUPINE PROBLEMS
by Daryl Fuller

By the way: porcupines LOVE the taste of brake fluid. They eat through anything rubber and even metal brake hoses, and often don't leave an obvious sign that they have visited. There is nothing more hair-raising than getting half-way back down a switch-back dirt or gravel road high in the mountains only to have NO brakes. I always take a roll of chicken-wire fencing with me if I am leaving my vehicle out in the back-country. I leave my vehicle surrounded (corralled??) by the wire. I have also used creosote soaked around my vehicle, as porcupines don't like the smell. This latter method is much less environmentally friendly so I haven't used it for 20 years or so.

Virtue is it's own reward - but most of us want a better deal.
