With the appearance of still another of the State Department's bill of particulars against Congress {''Wrecking State'' by Elliott Abrams, op-ed, Oct. 19}, we'd like to shed light on one point that has been conspicuously absent to date: namely, that the department itself shoulders substantial responsibility for the conditions it currently bemoans.

For those who have read recently of supposed crippling cutbacks at the State Department, we offer these facts:

In FY 79, total State Department spending was $1.6 billion. In FY 86, total spending was $4 billion -- a 250 percent increase. Just last year Congress provided a $2.1 billion multiyear embassy-security program to upgrade the physical, technical and perimeter security at more than 200 of our missions aboard.

The House-passed State Department bill for FY 88 contains an effective 3.5 percent increase over FY 87, at a time when federal agencies are scrambling for funds.

As to the complaint that the department has to cut back on jobs, readers should know that the number of American employees at State jumped from 10,900 in 1981 to the current 12,200.

With its mission so critical to our national interest, State more than any other organization should ensure that it is spending its appropriated tax dollars wisely. Yet, last year, it resorted to fiscal gimmickry in order to produce some budget ''savings.'' For example, the department pushed the purchase of furniture from one fiscal year into the next to yield reductions on its balance sheet that did nothing for real and serious long-term savings. At the same time, last year and again this year, the department fiercely guarded the pay bonuses that regularly boosted some employees' salaries over $100,000 -- an improper effort to circumvent the existing cap on executive and congressional pay.

Moreover, the department has been criticized for spending $5 million last March for Secretary George Shultz and 205 aides to take a trip of dubious purpose to China, a six-day venture during which a grand total of eight hours of meetings were held. This trip was taken at almost the same time the department proposed closing eight consulates, saving an effective $900,000 total per year.

We will concede one point in Elliott Abrams' article, however. He is entirely correct in recognizing the strained relations between Congress and the Department of State. And the tone of his article well represents the attitude and level of cooperation that has produced such a strain.

Consider one, not-so-isolated example, which occurred on the State Department authorization bill, for which our subcommittee is responsible. Assembling this legislation took more than three months. Yet, it was not until some 20 minutes prior to appearing before the House Rules Committee, the last step before scheduled floor action the following day, that we received word that the department opposed the bill -- although the department never told us directly.

We did not consider that to be in good faith. Further, the department's lack of understanding of Congress was displayed when the bill eventually went to the House floor. After the department opposed our amendment addressing the Moscow embassy and Mount Alto issues, the House approved the amendment by 414-0. This is a sad commentary on career diplomats for whom reading the other fellow's intentions should be a strong point.

If there is any chance that this situation will improve, the State Department must come to two realizations. First, pared-down budgets are a fact of government at this time. State thinks it performs an essential function, and that is true, but no agency of government today receives the amount of money it thinks it deserves. Thus, it should be a priority of all agencies, State included, to develop the wisest, not the most alarming, savings.

Second, the department must realize that its seeming distaste and disdain for Congress' traditional and legitimate role have taken their toll and must begin to repair the damage. Money won't fix what ails the State Department. The cure will require Abrams' superiors to visit Capitol Hill and make a sincere effort to work with Congress at solving the problems that concern us all. Reps. Mica (D-Fla.) and Snowe (R-Maine) are chairman and ranking Republican, respectively, of the House Foreign Affairs subcommitee on international operations.
