Virginia Lt. Gov. Charles S. Robb has finally found a resting place.

For weeks before and after his inauguration, Robb and his staff hunted about the Capitol area, looking for an office to accommodate him and his permanent staff of five.

Republican Gov. John N. Dalton did not take the lead in providing space for Democrat Robb, and House of Delegates Speaker John Warren Cooke, though a Democrat, frowned on suggestions that the lieutenant governor, an officer of the executive branch, be given a suite in the new General Assembly Building.

Robb's only duty is to preside over the state Senate. Yesterday, as Robb was asking the House Appropriations Committee for a two-thirds increase in his budget, he disclosed that Dalton had agreed to let him occupy the historic Bell Tower in the southwest corner of the Capitol grounds.

In recent years, the tower's three rooms, one on each floor, have been used by lowerranking aides to the governor.

Robb's plea for more money was based on his contention that his officially part-time office has become "a full-time responsibility."
