1. Introduction
===============

Here it is: the first "issue" of FrOg on-line for 1999.  The initial invitation
to subscribe was e-mailed to 15 individuals.  The message to two (Mark Leger
and, ummmm, wellll, me!) bounced.  Three other recipients did not reply, and
therefore are not receiving this issue.  So to the 10 subscribers: Welcome and
enjoy.

I have no interval at which I plan to publish these, nor any schedule.  I will
publish them when I have enough material to justify an issue, or when I receive
something that cannot wait.  Follow-ups will be published when appropriate.

Since FrOg on-line is distributed solely by e-mail, it must be written in a
form readable by all e-mail programs on all operating systems.  This means I
cannot use boldface, italics, varying fonts, attachments, or html.  So to
achieve emphasis, I stretch words out like this: e-m-p-h-a-s-i-z-e-d
w-o-r-d-s.  When you see stretched out words, mentally convert to italics.

One new feature I'm adding: the featured specimen.  I've seen several great
FrOg collections and numerous memorable FrOg specimens over the years.  I hope
in each issue to describe one special specimen: a specimen that is unique in
some way (pattern, assemblage, geology/mineralogy illustrated, etc.), and yet
is simple enough to be well described and mentally pictured without, well, an
actual picture.  These featured specimens can be from any collection, and the
write-ups can be done by anyone.  I will not reveal who owns the specimen
without the owner's permission.  I hope y'all enjoy this section of FrOg
on-line, and I invite everyone to e-mail me a description of a special specimen
from his collection.

2. Picking Table
================

I talked with Dick Bostwick recently about the Picking Table.  Here is what I
learned.....

One FrOg subscriber asked whether or not the spring 1999 issue of the Picking
Table has been mailed out yet.  Answer: no.  Some delays have been experienced
preparing the spring 1999 issue.  The fall 1999 issue is planned to be a color
issue, which is considerably more expensive than a regular issue.  The fall
1999 issue is planned to be a special 40th anniversary issue.  All things
considered, it was decided to be best to combine the two 1999 issues into a
single, special, color, 40th anniversary issue, hopefully to be out in time for
the Franklin Show in late September.  Since the FOMS consists mainly of
collectors, this issue will have a strong emphasis on collector stories.

Starting with the first Picking Table for the year 2000, the journal staff will
be as follows:

     managing editor             Peter Chin
     assistant managing editor   Wellington Chin
     associate editors           Gary Grenier, Earl Verbeek, Dan Mikletz
     senior editor               Dick Bostwick
     production manager          Tema Hecht
     history editor              Lee Lowell
     events editor               Steve Kuitems

Last year, Gary was the "editor" of these FrOg news group messages; now,
associate editor for the Picking Table.  Hmmmm.  Gary, should we consider you
to have been promoted?

In a late spring phone conversation with one of the new Picking Table staff,
there were indications that the Picking Table may evolve into something more
casual, more helpful and educational to the non-professional majority of the
FOMS membership, and easier for members to publish in.

3. Misc. News
=============

I asked Steve Misiur about the spring 1999 show.
Steve wrote:
-------------------------------------------------------------------------------
Dear Bill,
    We had just over 2400 visitors coming to the Spring
Show. There were about 60 dealers for the outside portion of
the show. Next year's theme is going to be a Million Dollars
in Gold and the show will expand into the Hardyston School
across the street so there will be two locations but with
the outdoor area only at the Littell Center.

Steve
-------------------------------------------------------------------------------
Dick Bostwick provided some financial information on the spring 1999 show by
phone.  Hopefully, I understood him correctly:
     $3000 "seed" money per sponsor
   + dealer (both inside and pond) fees
   + admissions
   + auction proceeds
   - show expenses
   - $3000 "seed" money per sponsor for next year's show
   -----------------------------------------------------
   about $1800 profit per sponsor.
The spring show had three sponsors: SHMM, FOMS, and NJESA.  Concessions
proceeds went to scouts, not show sponsors.  My effort to get this confirmed or
corrected by someone else was unfortunately unsuccessful.

Currently under consideration for the 1999 Franklin Show is a "dark pond".
This would be a swap-and-sell much like the "pond", but at a place and/or time
such that there will be sufficient darkness to make viewing fluorescent mineral
specimens easy and comfortable.  Most likely, this event will be in the GeoTech
Center at the Sterling Hill Mining Museum.  Still wide open is the day and
time, with Friday afternoon and Sunday morning being the main candidates.
Electrical power is expected to be available for UV lamps.  Stay tuned for more
news on this.  Thoughts anyone?

The Passaic and Noble Pits will be opened for collecting during the Franklin
show.  I was not able to get details.

4. Featured Specimen
====================

What first caught my eye about this specimen is the unusual but attractive
combination of rich pink Rhodonite and silvery Sphalerite in ordinary room
lighting.  The specimen comes from Franklin, and consists of Calcite,
Franklinite, Rhodonite, Sphalerite, Willemite, and other un-identified
minerals.  It measures about 10 cm x 13 cm x 5 cm.

In ordinary room lighting, the Calcite is translucent white, with its surface
being classic rhombohedral cleavage planes all over.  The Calcite is mostly
concentrated in a 7 cm x 4 cm roughly triangular area and a 3 cm irregular
area.  Additional Calcite occurs as grains a few millimeters across scattered
among Rhodonite grains.  The Franklinite is in grains a few millimeters across
mostly scattered in the Sphalerite, with the grains more concentrated around
the two primary Calcite areas.  The Rhodonite varies in transparency and ranges
in color from pink to deep pink.  It occurs in grains ranging in size from a
millimeter to about 1.5 cm, and distributed irregularly throughout the
specimen.  The Sphalerite is translucent, almost transparent in some grains,
and is silvery in color.  It is the dominant mineral in the specimen, occurring
primarily as a granular mass, with grains ranging from a couple millimeters to
nearly a centimeter.  The Willemite is not visible in ordinary room lighting
without magnification.  Finally, there are minor amounts of an un-identified
translucent dark green-brown granular mineral.

When illuminated with short wave ultraviolet, the Calcite fluoresces bright
orange-red.  The Willemite shows up as bright green coatings or inter-grain
fillings, a small fraction of which has a short-lived moderate intensity green
afterglow.  The Sphalerate fluoresces a rather weak to moderately strong
pinkish orange color, with a moderate intensity, long-lived, orange afterglow.

When illuminated with 312nm ultraviolet, the Calcite's fluorescence is a
moderate intensity orange-red.  The Willemite does not fluoresce.  The
fluorescence and the afterglow of the Sphalerite appears to be the same as with
short wave.

When illuminated with 352nm or 368nm ultraviolet, the Calcite fluoresces a
rather weak purplish red.  The Willemite does not fluoresce.  The Sphalerite
fluoresces a moderate intensity orangy pink, with a strong, long-lived, plainly
orange afterglow.

After the attractive pink and silvery combination in room lighting, the other
features of this specimen that stand out for me are the gemminess of the
Sphalerite, and the brightness, longevity, and strong color of the Sphalerite's
afterglow after exposure to long wave ultraviolet.

I never cease to be amazed at God's creativity as manifested in FrOg mineral
specimens.  This specimen certainly has served to enhance that amazement.

5. End Notes
============

There was extensive discussion about the "list" in one of last year's FrOg
on-line messages.  In both that discussion and in the fall 1998 issue of the
Picking Table it was disclosed that both Pete Dunn and John Baum have resigned
as "keepers" of the list.  I have neither seen nor heard anything about who now
keeps the list.  Questions:  Who is/are the new keeper(s) of the list?  Is Dick
Bostwick still the keeper of the FrOg fluorescent mineral list?  Who is/are the
keeper(s) of the list of minerals unique to the FrOg area?

Wanted: discussion of FrOg minerals, specimens, and science.  Also wanted: FrOg
related news and announcements about shows and other events; clubs, museums,
and other organizations.  E-mail to:
   mattison@thunder.nws.noaa.gov
The success of FrOg on-line depends on my receiving contributions.  It is my
hope that future FrOg on-lines will consist mainly of mineralogical and
geological discussion, and will be mostly a collection of e-mail from others
(like last year) rather than my own writing.

Feel free to pass this on to anyone you believe would like a copy.

If you know anyone who would like to receive future FrOg on-line messages,
please have them send their request to me by e-mail.
