chief <>t construction ol tiii^ exhibit, described the difficulties 

 encountered in the handling and supporting of so much massive 

 coral, .iikI of the methods used in representing truthfully a 

 scene under seas. 



Dr. Clark, in charge of Preparation, gave us a general ac- 

 count of the intricate variety of work required in order to re- 

 produce realistic groups of animals in their natural habitats. 

 This comprises the collection of the animals required for the 

 group, and of botanical specimens and other accessories, the 

 making of field color sketches and of plaster casts of leaves and 

 other parts of plants, and then, in the laboratory, designing and 

 constructing small models of the scene chosen, which serve to 

 visualize the group to be completed. 



In the laboratory where the accessories for the groups are 

 being prepared, Mr. Albert E. Butler, who has charge of this 

 delicate and important part of the preparation, told about the 

 making and coloring of wax flowers, leaves, and other parts of 

 plants, and of rock work, and of the assembling of other ma- 

 terial required. 



The mounting of the mammals themselves was explained 

 by Mr. Saunders, who also took us to the unfinished Akeley 

 African Hall to show us how the beautiful and comprehensive 

 plan of Carl Akeley is becoming a reality. Several of the groups 

 are already installed and now nearing completion, while the 

 work on the building and other groups is steadily progressing. 



Lastly we were conducted by Mr. Chubb to his Osteological 

 Laboratory in the Department of Comparative Anatomy and 

 to the Osteological Exhibition Hall where he is expressing action 

 and animal mechanics in mounted skeletons. In explaining his 

 manner of procedure, he told of the methods of obtaining 

 necessary photographic studies of animals in action, of the care- 

 ful study during dissection of the specimen to be mounted, the 

 cleaning and preparation of the bones, and then the reassem- 

 bling of these bones in life-like pose to express a specific action.
