It's actually a rendering of 'etc.'. '&' is 'Et'. I know Nokia's corporate font always used to have an ampersand which was clearly a ligature of the two letters, for example, similar in proportions to the second step in the following:

(which, of course, is latin
'Et alii/aliae/alia' are 'and others'; 'etc.' is 'and the rest'. Thus repeated etc.'s are redundant.
The ampersand symbol is derived from 'et'. as in 'et cetera'. If you look _closely_ at one, you'll even see where the 't' is crossed on the stroke that goes up-right from the bottom of the figure.
Care to guess what the 'C' stands for?
This is a _standard_ abbreviation in older writing.
Think of the tanks in "tank farms" -- where a bunch of fuel tanks are kept in a large compound -- the kind where the tank trucks go to fill up prior to delivering to the local fuel stations.
Nope -- it is for fuel tanks -- serious sized ones.
That is how it is used -- but for fuel oil or gasoline.
Not sure that I would lower a steel tape into a water well -- even assuming that the light could shine far enough down a well pipe.
Such a cluttered page, took forever to find what you were referencing-- reproduced here for convenience:
"A sign over a fireplace mantle in New Hampshire has this puzzle on it. I saw it in a charming old Inn while having dinner with friends in the late '70's, and it caught my eye. The last line seemed clear enough, but how about the rest?
If the BMT put more : If the B . putting : Never put more : over a - der You'd be an * it
So I scribbled it down, and when I got home tried to figure it out. Turned out that the terminology was kind of archaic, but then it was a puzzle from some word-playing "Yankee" made up over a hundred years ago. At first it's harder than it looks. Eventually it dawns on you what it's all about. Simple stuff, and kind of corny, too. Think of where the sign is located, near the grate of a roaring fireplace, where strangers might have helped out fueling the flames-- IF they knew their English!"
Answering your question, it's a two letter word which has 28 separate meanings in contemporary English. homophonic with the name for a 3 letter insect.

"If the grate be empty, put more coal on. If the grate be full, stop putting more coal on. Never put more coal on over a - der You'd be an ass to risk` it
'-' has me stumped so far -- should work out to something like 'hot cin(der)' I _think_. can't make 'dash', or 'hyphen' fit
"B" -> (archaic for upper case) "Great B" -> grate be ":" -> "colon' -> coal on ".' -> (older _British_ usage) "full stop" -> full, stop "*" -> "asterisk" -> ass to risk
Hey, it's not easy being a grammar policeman. It's like a lot of hard-won skills. Just when you really get the hang of dropping the pin in those little holes in a rotary indexing table, along comes CNC. d8-)
I guess I haven't been close to many big oil tanks. I guessed they weren't more than 30 feet deep.
This says the State of Kansas uses steel tapes to measure down to the water table in 1,380 wells each year:

the USDA recommends using a steel tape:

tapes pictured ought to work fine for water wells, but for water they recommend putting chalk on the tape so you don't have to worry about just how far to lower it.
