THE Summer Daily Vol. LXXXIII, No. 13-S Ann Arbor, Michigan-Friday, May 25, 1973 Ten Cents Sixteen Pages Gray: Nixon informed about staff isi Oyalty Implicated congressman kills self Thumbs up A jubilant President Nixon shows his enthusiasm at a dinner held last night at the White House for 450 former POWs and their guests. Nixon drew cheers when he lashed out at "those who make heros of people who steal secrets and give them to news- papers." WATCH YOUR STEP: Pigeon droppings'P stil Diacue 'U structures WASHINGTON UA - Former FBI acting director L. Patrick Gray III said yesterday that he warned President Nixon last sum- mer "that people on your staff are trying to mortally wound you." Gray made the disclosure before a closed session of a Senate ap- propriations subcommittee and was quoted by the subcommittee chairman, Sen. John McClellan, D-Ark.). GRAY TOLD the subcommittee, accord- ing to McClell-n, that he spoke to Nixon list July 6 after agreeing with Lt. Gen. Vernon Walters, deputy CIA director, that confusion had arisen about the investi- gation of Mexican aspects of the Water- gate case Former CIA Director Richard Helms has said that last dine 23, White House chief of staff H. R. Haldeman instructed Walters to tell Cray that the FBI should quash its Mexican investigations for fear of uncovering covert CIA operations in Mexico. Gray testified yesterday that the mes- sage was delivered and the FBI investi- gation was curtailed for a time, but that he went to Clark McGregor, director of Nixon's re-election committee, and asked MacGregor to inform Nixon that Halde- man's orders were causing a lot of con- fusion. ON JULY 6, Gray said, Nixon called him and .Gray told him, "Mr. President, there is something I want to speak to you about. Dick Walters and I feel that people on your staff are trying to mortally wound you by using the CIA and FBI and by con- fusing the question of CIA interest in, or not in, people the FBI wishes to interview. McClellan said Gray reported Nixon paused and then replied, "Pat, you just continue to conduct your aggressive and thorough investigation." In another development yesterday, a two-term congressman from Maryland's eastern shore apparently shot himself to death after newspaper disclosures that he received a $25,000 contribution from sec- ret funds of Nixon's campaign finance committee. The contribution to Rep. Wil- liam Mills was not reported to the Mary- land Board of Elections, an apparent vio- latlon of state law. Mills, 48, a Republican from Easton, Md., was sent to Congress in a special 1971 election. MILLS' LAST .KNOWN public act was a call to a Maryland radio station Wednes- day night when he recorded a statement: "I wish to assure everyone that I've done nothing improper." In Washington, U. S. Attorney Harold Titus announced yesterday that one key figure in the Watergate case will plead guilty without 'immunity and testify for the prosecution. Titus would not identify the mystery person. See NIXON, Page 12 By JUDITH RUSKIN The University has once again entered into battle with its age old enemy the pigeon. The battlefield has shifted this time from the lofty peaks of the law school to the steps of the University Art Museum in Alumni Memorial Hall. Apparently area pigeons had taken a liking to roosting on the lights above the museum entrance. This in turn created a hazard for all those entering the build- ing, as the front steps were covered with pigeon droppings. "Our porch was a mess!" said a mu- seum spokeswoman, Esther Allen. "We had a tremendous time keeping that porch clean. You can't wash that stuff off, you have to scrub it off," In a dramatic change of strategy, the University dropped the chemical war- fare plans it had previously used against the pigeons. Instead the Museum had the Plant de- partment encase the lights in a stainless steel wire mesh. The $700 charge for the pigeon protection also included the instal- lation of a bed of wire prongs along all the building's ledges, preventing the birds from making even a brief rest stop on their journeys across campus. But the attempt to roust the unwanted visitors was not completely successful. After installing the anti-pigeon fixtures, the plant department left its scaffolding on the museum's steps. The pigeons flocked from all over the city to make their new home atop the scaffolding. "There are dozens of them living up there," Allen lamented. Three weeks after the scaffolding had been erected, "our porch is still a mess," she said. The base of the steps was almost en- tirely covered with pigeon droppings. "I couldn't even sit down, it was so awful," one passerby complained. But all was not lost. A belated -call to the plant department by Allen remedied the situation. According to Walter Enners of the sheet metal division, the plant de- partment didn't know until yesterday af- ternoon that the scaffolding was still there. Evidently while the museum was wait- ing for the workmen to collect their equip- ment, the crews were waiting to be re- minded that it was still on the hall's front door step. "We'(the sheet metal people) didn't put it up and won't take it down," Enners said. "But I guess it's our responsibility to see that it's down." Within two hours of Allen's complaint the scaffolding had been removed, de- priving the pigeons of yet another home, The birds, however, had 'flown the coop and were unavailable for comment.
