April 2, 1967. The Johnsons are on their way from San Antonio to Austin:
“While flying over San Marcos, the President had the chopper divert off regular flight pattern and circle over the college (Southwest Texas State College)…
Arrive Balcones Research Center, landing in a field of bluebonnets which afforded much delight to the President and Mrs. Johnson.”
They are shown possible materials for the exterior of the LBJ Library, on the University of Texas campus. One type is emerging as a favorite:
“Several buildings are made, around the University and Austin, of the shellstone — the museum of history, etc. Mrs. Johnson said she favored this, for it has such as interesting texture and history since ‘it once lived on the floor of the ocean.’ Mrs. Johnson seemed to lean toward a shellstone with the Italian travertine floors….
The President said that all three — the shellstone and the New Mexico and Italian travertine—should be bid for the sake of good business. Thus also it could be justified that the reason a foreign product was imported was for economies sake, since a State Institution (The University of Texas) must take the most economical route.”
