 board of managers is authorized to hold and administer trust funds, and 

 it is hoped by the aid of gifts or bequests for special or general 

 purposes to expand its usefulness in directing investigation. Already 

 it has been favored by a bequest of a considerable sum of money by 

 the late ex-Chief Justice Charles P. Daly, which may be devoted to any 

 purpose determined by the board of managers.
