Maynard Bixby took a trip to England in 1884, returning to the U.S.
aboard the City of Rome, which sailed from Liverpool and docked
in New York on 28 Oct 1884. He took a similar trip 5 years later
in 1889-- perhaps these were mineral collecting trips. On that occasion
he returned to the U.S. aboard the Servia, which sailed from Liverpool
and arrived in New York on 13 May 1889. It seems possible that this
latter trip might have been a honeymoon trip as well, but Katherine
is not listed with him on the passenger list (wherein he is listed
as a "miner"). According to the 1910 census for Salt Lake
City, he and Katherine were married ca. 1888, but according to the
1930 census they had married in 1890 when he was 36 and she was
31.
In any case,
they were in Denver by 1890 and had moved to Salt Lake City shortly
thereafter. Maynard explored the Thomas Range in Utah for minerals
and staked several claims for topaz. One, the Maynard claim, is
still being mined for specimens. The mineral bixbyite, which he
discovered there, was named in his honor by Penfield and Foote in
1897. The red beryl also found there was named bixbite in his honor,
but was later discredited as a variety. Bixby also wrote articles
for The Mineral Collector, including "A collector in Colorado"
(1894), "A description of topaz crystals, their localities
and occurrences in Utah" (1895), "Idaho opals" (1894),
"Montana sapphires" (1896), "Notable minerals in
western mines" (1894-1895), "Notes on Collecting in Utah"
(1897), "Notes on western minerals"(1896), "Pseudomorphs
from Utah" (1895), "Rambles in Montana" (1896), "Topaz
and other western minerals" (1896), "A trip to Globe,
Arizona" (1897), "A trip to the Utah desert" (1897),
"A Trip to the Old Jordan and Galena Mines, Bingham, Utah"
(1896), "Utah notes" (1894). In the December 1896 issue
of The Mineral Collector Bixby published his first ad, full-page,
saying: "For several years I have collected the very finest
of the Utah minerals and have concluded to offer them direct to
collectors at the following low prices ..." In 1902 he published
the first edition of his authoritative A Catalogue of Utah Minerals
and Localities, and by 1916 had issued a fouth edition.
Maynard and
Katherine Bixby had four children between 1888 and 1900, but only
one of them (Ethel, born in New York in 1889) was still living in
1900, the others having died young. Maynard's occupation is listed
as "mining" in 1910 and he was self-employed. The 1890
census was destroyed by fire, but Maynard is listed in the Denver
City Directory in 1890, so at least we know where he was. On the
1900 census for Salt Lake City he listed himself as a "mining
broker."
Maynard Bixby
appears again on the 1920 census for Salt Lake City, but in 1925
he and his wife Katherine "M. S." Bixby and unmarried
daughter Ethel moved to San Diego, California. And it is there that
they both died: Katherine died on 11 Sept 1931 and Maynard Bixby
died on 18 Feb 1935, at the age of 81. It's unfortunate that Katherine
predeceased Maynard, because she would have been the best one to
write his obituary (none has been found in the California newspapers).

Notes for Collectors
of Minerals
Tintic District--This
district is noted for its fine specimens of the rare copper arsenates,
as well as for its great variety of mineral species. Pearceite in
crystals has been one of the rarest noted, and the specimens seen
have been most remarkable in size, the largest being a half an inch
or more across. The crystals are of tabular habit, coated with a
bluish substance, and were associated with small brilliant crystals
of enargite and anglesite. The crystals also show the peculiar triangular
markings noted by Prof. S. L. Penfield in describing pearceite from
Montana. Less than a half dozen specimens of this mineral have been
preserved. Zeunerite also occurs with exceeding rarity, the crystals
varying in color from yellowish to a deep olive, almost emerald
green. They are of thin tabular habit, the largest being less than
one fourth of an inch across. Olivenite has been abundant at times,
but the red tinted specimens have been quite rare. The red crystals
are usually very minute, and range in color from a light reddish
brown to a deep blood red. They afford beautiful mounts for the
microscope, and are usually found densely lining small cavities
in a hard silicious ore, occasionally with enargite, also with anglesite,
and included in the latter mineral. White olivenite occurs sparingly
in very delicate felted bunches of capillary crystals. Scorodite
occurs in crystals of fine quality, the largest nearly one fourth
of an inch in size, of a bluish green color, also of brown tints.
Leadhillite has been observed rarely, but the crystals seen were
of good quality, nearly colorless, and averaged possibly more than
a half an inch across. Anglesite occurs in a great variety of form,
and its crystallography would be well worth careful investigation.
Many fine translucent and transparent crystals have been collected,
ranging in color from colorless and white, to dark grayish, and
a fine yellow. Crystals measuring about two inches in length have
been preserved and larger specimens have been reported. Cerussite
has been seen rarely in beautiful nearly transparent twin crystals.
Cuprite is rarely seen crystallized. A small quantity of mimetite
was found, occurring in very delicate white, grayish and yellow,
long slender hexagonal crystals. Brilliant small crystals of enargite
have been observed at the mines of Eureka, also in large crystals
of dull luster at the Homestake Mine, near Silver City, and of smaller
size at the mines of Mammoth. Very fine crystallizations of this
mineral have been obtained at the Commercial Mine, Bingham. Mixite
has been collected at various mines of the Tintic District, but
of finest quality at the Carissa Mine, where it frequently occurs
in minute acicular crystals forming beautiful pale green velvety
surfaces, largely in a barite gangue. Notable crystals of brochantite
were found at the Eureka Hill Mine, the largest a half inch or more
in length, and of the wedge habit. No other locality has furnished
such crystals of this mineral. A very few remarkable crystals of
linarite have been seen. A few specimens of Utahite in good sized
crystals have been collected. Pseudomorphs in great variety occur
in the Tintic mines.
Topaz Localities--The
Thomas Mountain localities are situated in Juab County, about nine
miles in a northerly direction from Drum Springs, in the Detroit
District, or about 55 miles in a northwesterly direction from Desert.
The topaz crystals occur in cavities and seams of a light gray rhyolite,
a great belt of which has been pushed up for 20 miles or more in
both northerly and southerly directions from Thomas Mountains. The
loose colorless crystals are found on the hillsides, and in the
sands of the dry gulches, where they glitter in countless numbers.
The sherry colored crystals are obtained by blasting the richer
spots in the rhyolite, where the crystals are found attached to
the sides of the cavities, and frequently loose in them, with a
soft kaolin-like material. These colored crystals bleach very rapidly
on exposure to the light, and particularly when exposed to the direct
rays of the sun, losing nearly all color in a day. The writer has
been unable to find any explanation of this fact. The largest topaz
crystals have been found at the bixbyite locality in the Dugway
Range, about 15 miles from Thomas Mountains, and several miles southerly
from the Dugway grade. Opaque crystals of much larger size than
any of the transparent kinds, filled with quartz, and occasionally
with black cubes of bixbyite attached, have been found here sparingly.
The curious groups of opaque gray topaz from Thomas Mountains are
of exceedingly rare occurrence, in perfection, though many imperfect
specimens are seen. The more imperfect crystals of the gray topaz
appear as if eroded by some solvent. These topaz localities are
exceedingly interesting to the mineralogist, and good specimens
are obtainable at any time.
Tiemannite
and Onofrite--The locality near Marysvale has produced the only
crystals of tiemannite known, and many fine specimens have been
obtained, the largest probably one fourth of an inch across. They
are generally of the tetrahedral habit and highly modified. No crystals
of onofrite have been reported. These minerals occur in a limestone
gangue the crystals appearing in open trains. Crystallized specimens
are reported unobtainable now.
Orpiment
and Realgar--Probably the finest and largest known crystals
of these minerals have been found in the gold mines of Mercur, mainly
in the Mercur, Golden Gate and Brickyard mines. Crystals of great
perfection and an inch or more in length, have been collected from
these mines. The discovery of perfect crystals of orpiment including
many of twinned habit enabled the classification of this mineral
in its proper system of crystallization, viz.: in the monoclinic
system, the crystals hitherto found being so imperfect that it was
placed in the orthorhombic system. Groups of orpiment crystals occur
with realgar crystals rarely among them. Beautiful crystals of realgar
occur with crystals of calcite, and often penetrating the latter.
Variscite--Variscite
in large nodules associated with bluish wardite, has been one of
the notable finds in Clay Canon, near Fairfield. Large specimens
of fine green color, eight inches or more across, have been mined,
which, sawed into sections and polished, made showy specimens for
the collection.
Martite--The
largest crystals of this form of hematite known have been collected
at Twin Peaks, Millard County. Octahedral crystals, showing but
one termination, and five inches or more across, have been collected.
Groups of martite crystals are also sparingly seen associated with
crystals of augite and apatite. These specimens were collected in
the soil, and consequently somewhat bruised, but smaller crystals
are found in place in the eruptive rock of the mountains.
Rare Minerals--Among
the rare minerals, bixbyite, luckite, mallardite, wardite and utahite
have not been reported outside of Utah. A mineral, however, giving
the reactions and having the appearance of utahite, has been found
near Morenci. Arizona. Zeunerite is exceedingly rare at the mines
of Tintic but a half dozen or so having been preserved. It is possible
that a small percentage of uranium runs through some of the Tintic
ores. About two dozen specimens of lettsomite have been found, while
chalcophyllite has been reported in but one or two specimens. Carnotite
occurs in sandstone, near Richardson, also SE of Emery, Emery Co.,
and in other localities. Uraninite occurs in very small quantity
at the localities. Dufrenoysite and binnite are probably unobtainable
at present. The best specimens of covellite have been obtained at
the O. K. Mine, but the mineral is rather friable. Copper arsenates,
similar to those of Tintic have been found at mines near Clifton,
and with development of the prospects there interesting finds may
be made. The less rare molybdenite, which seems to be coming into
commercial use, has been found in several localities, but no crystals
have been reported. Utah has been and will continue to be an interesting
field for the mineralogist, and it is to be regretted that no institution
exists as in some neighboring States, to which the mines would be
obliged to furnish good specimens of the various minerals discovered,
for preservation in the interests of science.
