In March the Carnegie Corporation of New York made a grant or $100,000 to the Carnegie Institution for the construction of an auditorium at Cold Spring Harbor, to be used jointly by the Biological Laboratory and the Department of Genetics.Later on, the Association received from the Rockefeller Foundation a grant of $45,000 for modernization of the Laboratory's present facilities. The Carnegie Corporation grant should have answered theurgent need for more comfortable quarters for Symposia, conferences, and evening lectures, as well as indoor accommodations for recreational activities; and the Rockefeller Foundation grant should have provided ample funds for modernizing our dining room and residences and improving our grounds. Unfortunately for us, however, the Korean conflict arose, and created condi- tions that have had a tremendous effect on our planning. The auditorium was to have been erected as part of a larger building program involving labora- tories for the Department of Genetics.Since the start of the Korean in- cident, building costs have increased about fifty per cent, and for a time it seemed doubtful that we would be able to go through with our building plans. Just as this report is written, however, the Executive Committee of the Carnegie Institution has approved plans for the construction of the laborator- ies; and it now seems probable that ground will be broken for the new build- ings in the very near future.The Rockefeller grant, also, will not go so far under present circumstances.
