SUMMER A GRAB BAG OF FACTS AND ANSWERS ABOUT THE WARM SEASON

SUMMERTIME, AND the living is . . . queasy. You're perched on the very cusp of the season - rocking in the hammock, sipping a cool something - but deep inside, you're not quite as calm as you'd like to be. There are summer questions you still can't answer, riddles and puzzlers that have been gnawing at you for years like so many blood-crazed mosquitoes.

Relax.

Summer's no time for you to be worrying. Here at the Institute for Barely Relevant Information, we've done your worrying for you. We've plumbed the depths of human knowledge, circled the globe (well, the block) seeking facts and figures that make the whole hot-and-sticky thing a little more understandable. Summer's biggest issues and some of its most trivial pursuits - a few information-filled sentences can make all the difference, you know.

Or you can use the paper to swat bugs. HEAT BY THE BAGFUL

Where does charcoal come from? Glad you asked. The driving force, so to speak, behind the modern charcoal briquet is none other than Henry Ford, father of the Model T. A waste-hater from way back, Ford was looking in the 1920s for a way to turn wood scraps from his auto production line into money. His answer? Turn them into briquets. He teamed up with one Orin Stafford, who had developed a ``retort charring'' technology, and by the 1930s was selling those little pillows of fuel through Ford auto dealerships.

Ford's charcoal operation, by the way, was based in the town of Kingsford, Mich., and Ford Charcoal was eventually renamed. (You've seen the name.) In case you were wondering. WHAT'S ON THE GRILL?

According to the Kingsford folks, who keep track of such things, it's chicken leading the pack, showing up on the grills of 64 percent of barbecuers. Hamburgers and steaks check in with 57 percent and 56 percent, respectively, while hot dogs lag behind at 25 percent. Fish? Just 11 percent.

But wait! The latest numbers from the Barbecue Industry Association (of course there's a Barbecue Industry Association) put burgers on top, followed by steak and chicken in a virtual dead heat, and hot dogs. HERE COMES A TREND

The Barbecue Industry Association lists 1995 U.S. charcoal sales at 823,712 tons. That works out to - don't we make it easy for you? - 164,742,400 10-pound bags.

But don't turn up your nose at gas; if charcoal briquets had heels, LP gas would be nipping at them. The latest BIA survey finds charcoal grills in 56 percent of American households and LP gas grills closing fast at 55 percent. (That comes to more than 100 percent? Simple: Some people are multi-grilled.)

Meanwhile, the most popular ``aromatic wood'' is? Hickory, with

5.5 million pounds shipped in '95, followed by mesquite, with 3.9 million pounds. Are you an alder fan? You're a niche, Mitch: a mere 200,000 pounds. AND HOW MANY IN THE TRUNK?

Would summer be summer without a trip to the drive-in? Apparently. At their peak in 1958, there were 4,063 drive-in screens in the United States. By the end of 1995, there were only 848.

The state with the most screens? California - no surprise - with 131. But how about No. 2? It's Ohio with 63, followed by New York (44), and Indiana and Missouri (42 apiece). SING A SONG OF SUMMER

Everyone's got a favorite summer song; there are hundreds of them. But did you know: In the 40-odd years of the rock era, only two - count 'em, two - songs with the word ``summer'' in the title have ever been No. 1 on Billboard's Hot 100 or Top 100 charts. Can you name them? We'll tell you later. (Hint: One of them isn't even a rock song.) I'M HOT (AND I'M SMELLY)

If sweat came in a package instead of dripping off your nose, the ingredients list might read: water, salt, potassium, urea, ammonia, sugars, proteins and iron. Most people have two types of sweat glands. Eccrine glands react mostly to heat and show up all over the body, although they're concentrated in the armpits, soles and palms. Apocrine sweat glands react to emotional stimuli - stress or sexual arousal, for instance - and are concentrated in the armpits (busy place, those armpits), the groin and around the navel.

Eccrine sweat doesn't react with bacteria, so it stays odorless. Apocrine sweat, on the other gland, does react with bacteria, so you'd better be standing downwind. ARE WE THERE YET?

You thought you were the only one who's crazy about Triptiks, those hold-in-one-hand, personalized travel maps from AAA? Wrong. In June, July and August of 1995, the auto association issued 2,141,691 of the things - and they're predicting an 11 percent increase for the same period this year.

Do all roads lead to Disney World? It only seems that way. Actually, AAA travel managers project that this summer's most popular auto travel destination is indeed Orlando. The rest of the top five? Grand Canyon, Los Angeles/Anaheim, Williamsburg and San Diego.

AAA's domestic ``hot spots'' - this summer's destinations with a sudden surge in popularity - are Atlanta; Cleveland; Foxwoods Casino, Conn. (there's gambling there); Metropolis, Ill. (there's more gambling there); and Philadelphia. YOU'D PUCKER TOO

It's light, it's comfortable, it's perfect for summer. Wear it outside and some people will still laugh at you.

It's seersucker, the dimpled star of a million summer strolls. The secret? Alternating yarns woven at normal and slack tension. The slack yarns start to buckle during processing, and presto: a puckered stripe that won't cling to clammy skin.

Maybe the funny name accounts for the giggly reaction; what kind of a word is ``seersucker'' anyway? It's a Hindi word, actually - sirsaker - which came from a Persian word - shir-o-shakar - which literally means ``milk and sugar.'' Oh. WHY ME? WHY NOT YOU?

``Exactly what attracts mosquitoes to man or to one human being instead of another is not understood,'' says the Encyclopedia Americana.

Not quite, says Wisconsin entomologist Phillip Pellitteri. ``It's a body-chemistry kind of thing.''

The two biggest determining factors, he says, are a particular person's levels of carbon dioxide and lactic acid. The more of either you give off, the more attractive you are to mosquitoes. AND HOW DOES THAT WORK?

Carbon dioxide levels are generally similar among people at similar activity levels, but the more active you become, the more you'll produce. (On the other hand, the better shape you're in, the more efficiently you'll use oxygen, and the less carbon dioxide your exercise will produce.

Lactic acid levels, meanwhile, vary plenty from person to person. It's lactic acid that many insect repellents are designed to counteract, says Pellitteri; an effective repellent basically neutralizes the mosquitoes' lactic-acid receptors. The buggies may come close but then they get their signals crossed.

``The mosquitoes can't tell what you are,'' Pellitteri explains. ``And that's why they don't bite.''

Other, less important, factors? Body heat. Perfumes or shampoos that resemble the nectar mosquitoes imbibe when they're not drinking blood. And even, perhaps, hormonal changes - Pellitteri cites studies suggesting that women's susceptibility to mosquito bites varies during their menstrual cycles. SPEAKING OF WOMEN . . .

Only female mosquitoes bite; they need the blood to nourish their eggs. And it's not really a ``bite.'' Mosquitoes can't even open their jaws. Instead, they pierce a victim's skin with six needle-like ``stylets'' in the center of the proboscis. Mosquito saliva keeps the human blood from clotting while it's being sipped, and it's our allergic reaction to the saliva that causes the welt with the incorrect name. AND THE WINNERS ARE . . .

The second-biggest rock-era hit with ``summer'' in its title is ``Summer in the City'' by The Lovin' Spoonful, which held Billboard's top spot for three weeks in August 1966.

And the biggest ``summer'' hit? ``The Theme From `A Summer Place','' Percy Faith's instrumental and one of the top-charting songs of all time. It spent nine weeks at No. 1, starting in February 1960. February.
