Brunton Compass

Brunton Pocket Transit, folded for carrying.

This is a Brunton Pocket Transit.  Probably most people who know of them just think of them as the Brunton Compass.  It's an old, old design, having been first made in 1894, although the patent date on the compass references 1896.  I'd be curious to know when  they really started to be common, if we can consider a specialized instrument like this as ever having been common.

I ran across my Brunton compass recently as, for some reason, I'd taken it out of the carrier this fall in order to use it for something.  At this point, I frankly don't know what that something was, as I very rarely use it anymore.  I have a nice Garmin GPS with the topographic map software loaded into it, and I use that now, even though its a model that's now discontinued, and the last software up data makes it a little slow

Brunton Pocket Transit, opened for use in the geologists fashion.

I sure remember getting the compass, however.  It was in 1986, during my last year at the University of Wyoming, when I was a geology student. We had to buy them for our summer field course, which took us all over Albany and Carbon counties, mapping, and all the way down to New Mexico, where we did field work, as well.  At that time, having a compass of this type was an absolute necessity, and they saw 100% employment by geologists who did field work.  I'm told that at one time, graduates of the mining engineering school at the Colorado School of Mines could be identified by the short brim Stetsons they all acquired upon doing their field work (back in the sensible headgear days).  If so, graduates of any geology program anywhere could be identified by the fact that they all owned Brunton compasses.

Brunton compass opened up with mirror facing to catch the sight, in the fashion used by geologists in the field.

The reason for this wasn't fashion, it was necessity.  The compass is a precision instrument, and the official name of "transit" is accurate.  A transit is a surveying instrument, and so is a Brunton compass.  Extremely precise, the location of about anything can be accurately determined by triangulation or even just flat out using it in concert with a drawing compass (the plastic device) and a topographic map.  But we made topographic and geologic maps with them, which requires not only the compass, but more work.

Compass opened, showing the interior device for measuring angles, for determining elevation.  This one is not set, as the level clearly shows.

The reason that the compass can do this is that it not only features the typical magnetic compass feature, but it also has the ability to sight elevations with the use of an internal scale.  And when set on a Jacob's staff, a pole of a known size, distance on the ground may be measured over any sort of terrain while using that feature, with the compass attached to it, while the mapper walks over the ground.  A marvelous instrument.

My first exposure to this instrument didn't come in a geology class, however.  It came at Ft. Sill Oklahoma.  The Brunton Pocket Transit, to soldiers, is known as the artillery compass, and that's where I first learned how to use it, in basic training.

Compass set to site in the Army fashion.

I was actually surprised to learn, while a geology student, that my old friend the Brunton Compass, was used as a geologist's tool.  I just thought it was a marvelously precise Army compass.  Adapting to geology use was, therefore, very easy, even though the Army uses the sights differently.


Compass set to sight in the Army fashion.

Artillerymen used the compass as it is so much more precise than the conventional infantry compass, and artillery needs to be spotted accurately.  Even so, we never used it to the same degree of precision that geologists did.

Combined geology use and artillery use made me glad to have one, even when it turned out that I was never going to be a field geologist, that occupation having entered one of its cyclical slumps at that point in time at which I graduated from the University of Wyoming.  It's just been a field companion since then, which I used for many years when out in the sticks.

But not so much lately. As noted, I've gone to the GPS, although I was a late adapter of that technology.  Indeed, I hadn't looked at the compass for quite some time.

In looking at it, and then determining to post, I thought that it was probably a thing of the past now, but I see that this is one of those many things to which Yeoman's Second Law of History apply, they're still being made today. And they're still pretty pricey, although all in all I actually think they aren't as expensive in real terms now as they used to be.  Indeed, my recollection on this may be inaccurate, but I think the Classic model with the Aluminum body is now cheaper than the plastic cased variant shown in these photos.  It pleases me, frankly, so see that such a useful item is still in use.

I don't know if they're still in Army use or not, but I did learn the following, thanks to Gordon Rottman who sent me the text from his book on World War Two equipment:
M1 and M2 compasses with M19 carrying case This sophisticated compass was based on the William Ainsworth & Sons-made D. W. Brunton’s Pocket Transit dating back to 1894, but adopted by the Army in 1918. The M1 designation was assigned in the 1930s. The “artillery compass” combined a highly accurate surveyor’s compass with a clinometer (for measuring vertical angles and slopes), tubular horizontal level, and circular bubble plumb (vertical level). The circular level was for leveling the instrument before the azimuth values were read and the tubular level for measuring horizontal angles. There was an angle-of-site mechanism and an azimuth scale adjuster assembly making this a complex instrument requiring specialized training. It was used by artillery forward observers. It had a dustproof and moisture proof, dark OD-painted brass case (smooth or crinkled finish), squarish in shape with rounded corners, 2-3/4 x 3in and 1-1/8in thick; 5-7/8in long when  opened exclusive of the sights. A mirror was fitted inside the lid with a black sighting wire. The mirror also proved useful for shaving. There was a black folding front sight on the lid’s top edge. On the rear was a black hinged rear sight holder with a folding sight on top. The compass card was black with white markings. The M1 compass was graduated in degrees only and was phased out before the war by the M2 graduated in mils. M1s may have seen limited use. The mil scales was graduated at 20-mil intervals with 10-mil intermediate tick marks divided into 1-mil ticks. The angle of sight scale was graduated in mils in the same manner, 1200-0-1200 mils. On the compass card, north was indicated by a star and the other cardinal directions by W, S, and E. The radium-painted white end of the needle indicated north. The light brown leather M19 case had a rigid rounded pocket with a snap-secured lid and a trousers belt loop on the back. The rigid dark OD  plastic case (10543560) is post-WWII. Today it is known as the “M2 unmounted magnetic compass.” 0.5-b.
Pretty impressive.  Showing that the test of a tool is its usefulness, not its age.

What you reall need is a Holley Carb. . .



I've come to the conclusion that those who work as computer geeks today are drawn from the same section of the population that once went into small shop mechanics.

Back in the 70s and early 80s, before computers invaded the automobile world and changed auto repair from a trade into a computer lab project, there were many small auto mechanic shops staffed by men in their 20s who wanted to mess with your car.  No matter what your problem was, when you contacted them about the repairs to your car, you were soon confronted with the "performance" changes that they wanted to make to it, or worse, already had.  "Man. . . this baby needed a Holley Carb!  I just ripped that old stock carburetor off and . . ."

At that point, you were doomed.  No aftermarket performance part so installed ever worked, and at best, with enough tinkering, your car might get back to the original state of performance, more or less.

Computerization of automobiles ended that.  So now, the same people go into computer programming.

If you work in an office, you know this is true. The moment your system is really working well, you are going to face an "upgrade", or worse, and entire new system.  If you are lucky, after days of messing with it, and hours and hours of lost work, you'll get a system back that is close to what you had.

Office machinery and the written word.

Just recently, I resumed using the Dragon voice recognition system for dictation. For those not familiar with it, it's a program that jacks into your computer, and you speak into a microphone
which then processes the spoken word immediately into print. This is the second time I've experimented with. The first time, I grew frustrated with it and, after the system collapsed, I abandoned using it and simply typed things out on my computer. I'm a pretty fast typist, so this was working well, but any way you look at it, it's slower than speaking. This time around, the Dragon system seems to be working very well, so I've very happy with my resumed use of it.

Anyhow, what a revolution in the process of generating pleadings and letters this is. When I first started practicing law, some 21 years ago, we were using Dictaphones. Now those are practically a thing of the past. For those not familiar with them, a Dictaphone is a specialized tape recorder that allows the speaker to dictate the document. This ended up, at that time, in an audiotape which was handed over to the secretary, who then listened to it and typed out the document. The secretary handed that back to you, and then you manually red lined it for changes. This process could take some time.

This, of course, was an improved process of dictation as compared to the original one, which entailed calling a secretary in to your office and dictating the document to her. She took it down in shorthand. My mother, who had worked as a secretary in the 40s, 50s and 60s, could take excellent shorthand as a result of this process. Now, shorthand is nearly as dead of written language as Sanskrit.

Even earlier than that, legal documents were processed through a scrivener, a person whose job was simply to write legibly. That person wasn't normally the lawyer.

I'm not sure if this entire process is really quicker than the older methods, but it is certainly different. My secretary only rarely sees a rough draft of anything. That rough draft goes on my computer, and I edit it from there. About 80% of the time, by the time I have a secretary proof read a document, it is actually ready to go. Those entering the secretarial field, for that matter, generally no longer know how to take shorthand or even how to work the Dictaphone machine. They're excellent, however, on working the word process features of a computer.


All this also means, fwiw, that the practice of law, at least, is a much more solitary profession than it once was, at least while in the office. Generating a pleading, in a prior era, was more of a community effort in a way. The lawyer heard the pleading for the first time, in many instances, as the same time his secretary did. Over time, most secretaries were trusted to make comments on the pleadings. In the case of letters, they were often simply expected to be able to write one upon being asked to do so, something that still occurs to some degree today. But for pleadings, today, a lawyer tends to wall himself off by himself while drafting them, and any outside input tends to start after a relatively complete document has been drafted. Of course, with computers, it's much easier to circulate drafts and to change documents as needed.

The Speed of Cooking

I received an unexpected and surprising of how much things have changed even in my own lifetime this week, and in the kitchen at that.

Last week I happened to have to go to Safeway to buy some odds and ends, one of which was breakfast cereal. I'm bad about buying the same kinds again and again, so I decided to add some variety. It's been fall like here, so I decided to go with hot cereals for a change.

But not only did I decide to go with hot cereals, but I bought Cream of the West and Irish Oatmeal. That is, I did not buy instant Cream of Wheat, instant Oatmeal or quick oats.

Cream of the West is like old fashioned Cream of Wheat, except its whole wheat. Frankly, the taste is identical to "regular" Cream of Wheat. Irish Oatmeal, however, is really porridge, and it has to be cooked. It actually has to be cooked and allowed to stand, so it isn't speedy.

Anyhow, my kids have never had "regular" Cream of Wheat. They like "instant" Cream of Wheat, which has an odd texture and taste in my view. Sort of wall paper paste like. Anyhow, my son cooked some Cream of the West the first day I did, with us both using the microwave instructions.

He hated it. He's so acclimated to the pasty instant kind, he finds the cooked kind really bad.

Both kids found the porridge appalling. They're only familiar with instant oatmeal, and they porridge was not met with favor at all. I really liked it. It's a lot more favorable than even cooked oatmeal.

Anyhow, the point of all of this is that all this quick instant stuff is really recent, but we're really used to it. During the school year my wife makes sure the kids have a good breakfast every day, which she gets up and cooks for them. But it never really sank in for me how much our everyday cooking has benefited from "instant" and pre made. Even a thing like pancakes provides an example. My whole life if a person wanted pancakes, they had the benefit of mixes out of a box. More recently, for camping, there's a pre measured deal in a plastic bottle that I use, as you need only add water. A century ago, I suppose, you made the pancakes truly from scratch, which I'll bet hardly anyone does now.

A revolution in the kitchen.
