Feet, don't fail me now. Do a little dancing if you like. Because there is reason, feet. Three hundred and fifty one reasons, to be exact. Our annual fund-raising campaign on behalf of Children's Hospital isn't heading for the stratrosphere. It's already there.

Our Week Six totals have just come churning out of the adding machine, and the news remains as good as it has been throughout the 1987-'88 campaign. The figures:

Grand Total to Date: $351,289.05.

Total Given This Week: $83,640.07.

Individual Donors to Date: 3,129.

Group Donors to Date: 714.

For those of you who like to compare numbers, the grand total is better than we ended up with in three of the last six campaigns, and we are only at the three-quarter mark of this one. The group donors total is the best we've ever turned in after six weeks. The total given this week marks the first time in the history of the campaign that we've logged three $80,000-plus weeks in a row. All in all, a tremendous performance.

Let's top off that tremendous performance with a tremendous Final Fortnight. Let's surge past last year's record of $429,000. Let's see if we can get close to half a million bucks (or perhapsd past it?) for the first time.

Our campaign depends on readers just like you, as it always has. As you can see above, group donations are doing well this year. But the backbone of the Children's drive is the $10, $20 and $25 check from the typical reader of Bob Levey's Washington.

We hope that you'll contribute -- and contribute generously -- if you haven't already. Please remember that all the money goes to pay the medical bills of sick kids whose families can't afford the care, or don't have insurance, or both. You will never meet a more worthy cause than that.

Thank you very much in advance.

Campaign addenda: :: An additional donation from the American Gas Association has pushed that outfit's contribution from the $345 I reported on Jan. 5 to $807. :: In reporting a $340 donation from the employees, National League of Postmasters and Postmasters Benefit Plan, Alexandria, I said that the money was Laurie Ruxer's. In fact, the idea to donate the dough was Laurie's. But the dough itself belonged to many, many generous employes of both organizations -- to whom large sorries for misrepresenting things.

TO CONTRIBUTE TO THE CAMPAIGN:

Make a check or money order payable to Children's Hospital and mail it to Bob Levey, The Washington Post, Washington, D.C., 20071.

THE CAMPAIGN ENDS ON JAN. 22.
