The U.S. government is passing out 1 million multicolor pamphlets (estimated cost, $25,000) to its employes, advising them to wear warm clothes this winter.

Produced by the General Services yadministration, the four-color winter wardrobe guidelines, called Staying Warm, pick up where your mother left off. w

Uncle Sam says, for example, that long-sleeve shirts are warmer than short-sleeve shirts; that thick socks and sensible shoes keep your tootsies toasty, and that if you open a window in the dead of winter you will let cold air inside. Workers are also advised to eat well-balanced, hot meals. To warm the inner G-man, the federal pamphlet suggests a bowl of hot chili, rather than a martini, for lunch.

The new brochure is part of the GSA,s energetic and imaginative energy conservation program. It has encouraged car-pooling and engineered the hot water shutoff in federal restrooms here, among other things.

Earlier this year, back when it was hot, GSA put out a bulletin telling federal workers how to stay cool. It was almost exactly like the Staying Warm message, except it told people to do just the opposite, since staying warm is different from staying cool.

Since only 1 million of the pamphlets have been produced, many of the 2.7 million federal workers anxious to absorb the advice will have to share copies. m

Although some of the pamphlet's advice (..."take special care to keep your neck, arms and feet warm" or that slacks for women are "warmer than a dress") is rather basic, U.S. officials think much of it is worth repeating, 1 million times. For example, the pamphlet says:

Heavy socks and loose shoes are warmer than thin socks and tight shoes.

A three-piece suit, or suit with a sweater, is warmer than a two-piece suit.

Lightweight sweaters make you two degrees warmer.

Heavyweight sweaters make you foru degrees warmer.

Wool is warmer than lots of other stuff.

Close doors to avoid drafts.

Although some federal workers are amused, or incensed, at the don't-stick-beans-up-your-nose logic of the pamphlet. GSA's energy office believes it is a good thing and that there is no harm in putting the government's official seal of approval on horse sense in this day and age.
