5 8 Report of the President 



This will form a most instructive companion piece to the great 

 glacial groove slab that was secured on Kelley's Island in 

 1909 through the Dr. C. E. Slocum Fund. The Curator spent 

 the month of October in Arizona collecting the material already 

 mentioned as coming from Bisbee and Adamana. Messrs. 

 S. S. and I. S. Simons were employed for several weeks col- 

 lecting the Cambrian trilobites that came from near Lancaster, 

 Pennsylvania. Special assistants were employed in the sum- 

 mer, and much progress was made in overhauling and placing 

 catalogue numbers on the rock collections in the department. 

 The great Hitchcock series illustrating the lithology and gen- 

 eral geology of Vermont and New Hampshire is now in better 

 shape for study than ever before. Steady progress has been 

 made on the model of the Copper Queen Mine, three and 

 sometimes four men being employed upon the work at once. 

 The building of the wooden form for the surface and the 

 modeling of two sections thereof were completed. Several 

 experimental studies were made for the representation of the 

 underground portion of the mine, which is the part of the 

 work that presents the most difficult problems. 



For various reasons, the rearrangement of the hall men- 

 tioned in the last annual report has not been begun, but it will 

 be undertaken at an early date. A model of the proposed 

 gallery and floor cases was prepared and filled with specimens 

 to show different methods of installation. The specimens 

 illustrating historical geology present more difficult problems 

 regarding installation than do those of any other branch of 

 natural history, and an effort is being made to secure results 

 that shall be not only instructive but also pleasing to the 

 general public as well as to visiting scientists. 



The work of the department was interrupted somewhat 

 through the Curator's being detailed to service as Acting 

 Director of the Museum for three months of the year.
