The D.C. branch of the well-known Ruby Foo’s chain opened in 1942 at 728 13th Street NW. Ruby Foo Wong (1904–1950) had opened her first Ruby Foo’s Den in Boston in the late 1920s to great acclaim. More sprang up in New York City before Wong’s brother opened the Washington restaurant. More a supper club than just a restaurant, Ruby Foo’s featured dining on the first floor, dancing and entertainment on the second and “exotic” Chinese décor throughout. In 1943, the second floor was remodeled as a Tahitian Room featuring Hawaiian dancers and jungle greenery. The restaurant suffered a setback in 1950, when cases of colorful Ruby Foo’s matchbooks like this one caught fire in the rear, starting a blaze that resulted in injuries to 13 firemen. The club closed in the late 1950s.

Ruby Falls, located 1,120 feet underground inside Lookout Mountain with a height of 145 feet, is one of the tallest underground waterfalls in the world.
The falls were discovered by Leo Lambert in 1928 and named them after his wife, Ruby. Earlier this year, the cave was closed for 3 days after heavy rainfall flooded a portion of the caves.
If you haven't visited here, you need it. It's quite the experience.

Notice the spider web (or is it a sticky situation) streaming from the beak of this female Ruby-throated hummingbird to the lily's stigma. They use spider web as "glue" to hold their nesting material together.
Experience is never limited, and it is never complete, it is an immense sensibility, a kind of spider web of the finest silken threads suspended in the chamber of consciousness, and catching every air-borne particle in its tissue". ~Henry James
Cool Facts From: www.hummingbirds.net
The walnut-sized nest, built by the female, is constructed on a foundation of bud scales attached to a tree limb with spider silk; lichens camouflage the outside, and the inside is lined with dandelion, cattail, or thistle down. The nest will stretch to contain the growing nestlings, and may sometimes be reused (rebuilt) the following year.
The rain stopped for a moment this afternoon and the birds noticed. Birds singing everywhere. This Ruby-throated Hummingbird (Archilochus colubris) female hovered around the feeder and rested a few times on a nearby twig.
The light was still poor: ISO 1000 and f/10 only gave 1/60 sec exposure. Handheld, no flash, 500 mm focal length, cropped by about 40 %.

RUBY-THROATED HUMMINGBIRD-08211712
Bunkhouse; Mining began in the area, a short distance north of the border with Mexico, during the 1870's leading to the formation of the town. Ruby became one of the largest mining camps in the area, with a population of 2,000 residents, and prospered until 1940 when the ore in the mine played out. The mine was closed in 1941 and the town almost immediately became a ghost town.
In the Northeast, our only breeding hummingbird is the Ruby-throated Hummingbird. Their nest is hard to find (it's a little bigger than a quarter), but is a sight to behold, made entirely of spiderweb encrusted with flakes of lichen -- a masterpiece of engineering and design! For safety from predators, they seem to favor building their nests on branches overhanging water.

Kinglets are tiny insectivores that actively forage for insect and spider eggs on the undersides of foliage. They weigh less than an ounce and are among the smallest of songbirds. They often hover in front of a branch, gleaning food from its tips and undersides. Kinglets often flick their wings as they move about.

You rarely see the "ruby" color on their little heads, so I was tickled when I got a tiny glimpse of that on this Ruby-crowned Kinglet. Look very closely.
FOV: 6" wide.
This experiment was an attempt to recreate the fluorescence of chromium activated corundum (aka 'ruby'). Aluminum hydroxide was mixed with 1-4 drops of Cr(III) oxide in a basic solution. This was placed on a small amount of aluminum sulfate in an aluminum foil container and a bit of water was added.
The sample was then heated, first with a propane torch until the water was removed and then with a MAPP gas torch until the aluminum sulfate expanded into foam, trapping the aluminum hydroxide which was calcined into aluminum oxide by the torch's flame. (at least that was the plan)
Shown also is a natural ruby from Mysore, India.

Ruby resides on my refrigerator. She is a magnet.....for attention!
She came with a bikini, and some type of pajama/summer outfit.
She loves her new golfing clothes. I told her not to accept any text messages from a man named Tiger!
Merry - Merry Happy - Happy!
