A sealing system for a pump having a plunger includes a housing having an internal chamber adapted to receive a portion of the plunger. Primary and secondary seals are located within the internal chamber and adapted to sealingly engage the plunger. The primary seal communicates with the fluid being pumped. A barrier fluid chamber contains a barrier fluid in contact with the primary seal and the secondary seal. A pressure referencing device has an inlet port in communication with the pumped fluid and an outlet port providing fluid at a pressure magnitude equal to a peak pressure of the pumped fluid. A pressurizing device is in communication with the fluid at the peak pressure and the barrier fluid to maintain the barrier fluid pressure at a magnitude greater than the peak pressure of the pumped fluid such that the pumped fluid is restricted from leaking past the primary seal.

Activists in the Black Lives Matter movement recently published a 10-point plan to reduce police violence. Rockford leaders are responding to the proposal. It’s called "Campaign Zero." National activists want stronger guidelines limiting the use of force. They also want to ban police quotas for tickets and arrests , and end the sale of military weapons to police forces. Rockford Mayor Larry Morrissey: “I don’t know that it’s intended to be a one-size solution. It lays out a series of agenda items. We are already moving forward on a vast majority of what I think those items are.” Morrissey says new measures at the state level are also intended to address interactions during field interviews, or a so-called “stop-and-frisk.” “The next step will be, starting next year, we will have to give a receipt to the individual so they know who is the officer-- and their badge number. If they have a complaint to file, they will have more information to do that.” Matthew Simpson co-leads My Brother’s

Look what I found!

Some time ago, I posted every page of the Image Notebook I created to help me imagine the world and people of Industrialized Faerie for The Iron Dragon's Mother. What I didn't mention was that it was actually the second such notebook I'd made. The first notebook I lost--forever, I thought. But as it turned out, it had been misfiled in my office.

This is why you should clean your workspace at least once a decade.

The Zero Notebook, as I think of it, was begun all the way back in 2009. I pasted images from magazines and newspapers into it, created collages, some of which I altered, sought inspiration from the uncanny but visualizable. The end result is something very close to (but not identical with) outsider art.

I'll spare you the bulk of the images. But starting today I'll be posting ten images from the notebook. One on each weekday when I don't have any other news to pass along. This is the first one: the notebook's cover.


And what, you ask, does it mean . . . ?

The eye, of course, represents the eye of a dragon. It's slashed across the oval to create a zero.  The dot to the lower right is meant to suggest that the glyph represents the letter Q.,  though, of course, not exactly. That's because I wasn't looking for Answers. Just Questions.

There are a few (not many) words in the notebook. Here's an entry I ran across that begins with (almost) the cover glyph:

Q. What does the Goddess want?
A. Wrong question.

All of the above carried through into the novel and became a major, if close to undetectable, theme. The Iron Dragon's Mother would have been a very different book if I had started it with a different image.

The crinkly stuff is wide transparent tape, used to seal the image onto the cover. If this notebook ever winds up in somebody's collection, that's going to be a major conservation issue. Not my problem.


Above: First image. Nine to go.

Here on the inside cover of the Zero Notebook is a first glimpse of Caitlin. It's a photograph of a young Russian doctor and, although it misrepresents Caitlin's ethnicity entirely, it does capture her innate seriousness. Added to which are birds in flight, because flight is in her nature, and a miniature of a painting by Lucian Freud. This last was included for its lack of glossy magazine glamor but also, with a touch of irony, because I knew that the novel would be going deep into Carl Jung territory.


And what, you ask, does it mean . . .?

It doesn't. The page is a first, fumbling-in-the-darkness attempt to find the heart and soul of the novel.


Above: Second image. Eight to go.

Excerpt 3 from the Zero Notebook for The Iron Dragon's Mother.  Jinx is a pretty neat character. I'm sorry I couldn't find a place for her in the novel. She looks like trouble, doesn't she?


And I have to apologize . . .

I promised to post these on every day I didn't have news and then got so caught up on writing chores I lost track of the blog entirely. My bad. I'll do better, I promise.

For a while, anyway. 


Above: Third image. Seven to go.

Another character that didn't make it into The Iron Dragon's Mother. Industrialized Faerie is a rich world. The three novels I've set in it can only only hint at how rich and strange it is.

This image, for a rarity, was hardly altered at all.


And where, you ask, did I find this. . . ?

The image came from the Body Works show that toured the world some years ago. A large number of corpses were flayed and then carefully preserved, in order to display the wonders of anatomy. The show was controversial at the time because the corpses came from China and there were those who claimed the bodies hadn't been voluntarily donated but those of criminals who had died in prison. The truth of the matter was impossible to ascertain.

The show, however, was extremely popular. My son, Sean Swanwick, worked for a summer as a guide when it was displayed at the Franklin Institute and he told me that they had to watch the people touring it like hawks... Every now and then, someone would try to snap off a finger or other appendage to take home as a souvenir.


Above: Image five. Five more to go.

She never appears in person in The Iron Dragon's Mother, but Mother Eve is central to the entire enterprise. Unsettling, isn't she?

Judith Berman once told me that most of the First People have Trickster tales. But of the hundreds of tribes in North America, only two--and they small tribes--have a female trickster. The female trickster is, apparently, difficult for people to imagine.

So you can imagine my delight when I found one right inside my own culture.


But what, you ask, does it mean . . .?

Trickster is a strange and difficult character, neither a good guy nor an evil one. She exists somewhere in between, a creator of chaos and a provider of a special Something that it seems human beings require. It might be corn and it might be fire. Trickster gets blamed for a lot of the woes of existence, but it seems that without him/her, we're skunked.

I wonder if Pandora was originally a Trickster,  before they allegorized her to hell and back? It bears thinking on.


Above: Image Six. Four to go.

Introducing Helen. There's more to her than meets the eye.

Written upside-down--so they won't necessarily be taken as gospel by any readers are three quick notes scrawled to myself:

Mother as Mind Spider

Storyteller as Spider & Weaver

Chrone as Spider

I apologize for the misspelling of "crone." But I was writing (and thinking) too fast to care much for accuracy.


But what, you ask, does it mean . . . ?

The influence of Louise Bourgeois is pretty obvious here. Late in life, she created those wonderful, terrifyingly realistic giant spiders with long steel needles at the end of their legs and said that they were all about her mother. Who made a living repairing tapestries, using long steel needles. So it's not the slap in her face it might seem.

I liked the spider representing the archetypal woman-as-maker, which fit Helen right down to the ground. I was also fighting a fight all the way through with received archetypal images of women were were almost all pretty or dainty or passive. I wanted to get at that primal fierceness that lurks inside us all.

And, ounce for ounce, you don't get much fiercer than a spider.


And tomorrow and Friday . . .

There will be news.


Above: Seventh image. Three to go.

Originally, this was going to be a character named Frog--one who never materialized in The Iron Dragon's Mother. A wood-fey, obviously, and possibly a marsh-weller.

But look at that wistful, lost expression. I think this guy eventually became Fingolfinrhod. I really do.


Above: Image Eight. Two more to go.

Dragons are, as everybody knows, half fighter jet and half fire spirit.

Here's the skull of one.


Above: Image Nine. One more to go.

Our revels now are ended. These our images, as I foretold you, were all spirits and are melted into air, into thin air...

But before we go, one more page, the back inside cover to be specific. It contains two more images of Helen. One is a publicity shot from a period she was going to leave out of the autobiography she never wrote, when she made a brief, ill-fated stab at acting. The other is from a dark period in her middle age.

She was far better-looking than she'd ever admit to being.


And what, you ask, does it mean . . . ?

To find that out, you're just going to have to read The Iron Dragon's Mother, now aren't you?
