Report of the President 63 



fite (from Professor A. La Croix, Paris), Cebollite, Creedite, 

 Hodgkinsonite, Parahopeite, Seartesite, Shattuckite and Wiik-

 able private collections of minerals will form one of the com-

 culture. A bust of Mr. John Muir, executed by the same artist, 

 has been offered to the Museum by Mrs. E. H. Harriman. 



Studies for the mural for the east end of the hall were made 

 during the summer by Mr. Hobart Nichols, and a quarter-size

 and between the trees in the distance the forest-covered moun- 

 tain slopes of a watershed. 



The department counts itself fortunate in having secured 

 the artist, Mr. Milton D. Copulos, to carry on the work of 

 preparation of sprays of flowers, fruits and leaves for the trees 

 of the hall. The quality of work now being done reaches
