Contributions came in this morning from 27 anonymous District Liners for Children's Hospital, where patients are never turned away because their parents might not be able to afford necessary medical treatment. The letters contained a combined total of $1,260 for the free-care fund.

Here's an interesting, painless way to raise a significant personal contribution, sent in by a concerned and generous young woman.

"I have a tip I would like to pass on to your readers on how to save money to send to the hospital. I am a college student who is on a very strict budget, but included in my weekly budget is a weekly contribution to Children's Hospital. Last year I put one dollar away each week. I put the money in a half-gallon milk container, along with all the pennies I receive as change. I don't think I've spent a penny in almost eight years; I would rather receive four pennies as change for the hospital than spend one penny and take it away from the children."

Next year our friend is putting away two dollars a week and collecting pennies daily. Her formula resulted in an $85 check for Children's.

Another writer gave thanks for the release of the hostages by sending me a $50 check for the hospital.

"Our contribution is . . . a token of gratitude for their release from Iran. We are challenging all Americans to do the same."

That's a challenge that I hope will be hard to resist.

Joining the fight against the "built-in deficit" were the following 13 area groups and organizations.

Members of the Joseph F. Barr Washington Ladies Auxiliary No. 58 of the Jewish War Veterans of the U.S. sent the kids $25. Also contributing $25 to the free-care fund were staffers of the General Legal Services Division in the Office of Chief Counsel at the Internal Revenue Service.

The folks at the Population Division of the Census Bureau collected $26 before Christmas. They hoped "it will be of some assistance to the 'hospital with a heart.'"

Once again the MG Car Club Ltd. of Washington balanced their books by contributing the "larger than normal surplus" of $27.72 to the shoebox. "Better late than never" was the message from the workers at Chemco Photoproducts of Rockville that accompanied their check for $40. The two employes that run "Antiques Uniques" from the basement of their home in Vienna sent in $50.

Housing sales may be down this season, but as usual, the kind people at Mike Casey Realty are up to their usual tricks. They collected $70.

Taking us into triple-digit territory with a contribution of $100 were employes of Jaynor Inc. in Falls Church. They sent a poetic message in with their check.

"Our slow reactions and procrastination, overtaken this day by our good intentions," they wrote.

Members of the staff of the Congressional Joint Committee on Taxation gathered $120 for the needy patients at Children's Hospital.

The Internal Affairs Division of the Metropolitan Police Department collected $125.75 for Children's instead of exchanging Christmas cards. Using the same method, the personnel of the Office of Safety in the Federal Highway Administration joined in our fund raising efforts with $127.

The "in lieu of" plan also worked for the staff of Wakefield High School in Arlington. Each member was requested to bring in just one Christmas card for the entire school staff and post it in the main office, where "Santa's stocking" was hanging to receive contributions for Children's. The staffers filled that stocking with $157.

"The employes of our firm again take pride in contributions to Children's Hospital in lieu of Christmas cards exchange," wrote a colleague at the Wm. E. Miller Furniture Co. "Enclosed find checks totaling $319.50." t

Those 13 groups added $1,212.97 to the $1,260 sent in by anonymous contributors for a daily total of $2,472.97. Last Friday the shoebox held $156,603.61, so with today's infusion of concern, it now holds $159,076.58.

Today marks the start of our final mail pipeline week. After next Saturday, only the letters still in transit will be counted in this season's grand total. Any checks arriving after Jan. 31 will count in the 1981-82 campaign.

So don't delay! Please send your tax-deductible check, made payable to Children's Hospital, to: Scott Chase, c/o The Washington Post, 1150 15th St. NW, Washington, D.C. 20071. Time is running short!
