 capped with cut stone, on which the iron fence will be erected by 

 May 15. 



Excavations havle been made for the walls and stone work of 

 eight Wolf and Fox Dens, and the walls have been laid ready for 

 the cage work. 



About five hundred cubic yards of sandy earth have been hauled 

 to the Pheasants' Aviary, to make dry ground for the runways. 

 This was removed by necessity from the Bear Dens, at no cost to 

 the Aviary. 



The excavation for the Beaver Pond has been completed, and 

 all the grading necessary thereto ; the iron fence has been made, 

 and a suitable foundation wall to support it is now being con- 

 structed. 



The excavation necessary for the Buffalo House has been com- 

 pleted, and the foundation and side walls are ready for the wood- 

 work. 



Stone walls have been laid, with proper drainage, at the Burrow- 

 ing Rodents' quarters, to carry the fences. Total length of walls. 

 643 feet. 



A considerable amount of grading has been done on the eastern 

 side of the hill for Mountain Sheep in properly exposing the rock ; 

 and a great quantity of loose stones and rubbish has been removed 

 from the base of the hill to increase its height. 



One thousand feet of plank and 500 feet of macadam road have 

 been built to enable teams hauling materials to reach the Reptile 

 House and Bear Dens ; and about 1000 feet of plank walks have 

 been built for temporary use. A large temporary wooden shed 

 28x96 feet has been erected for use as a general storehouse, stable, 

 tool-house, etc. 



Several thousand cuttings of willow and other species of trees 

 and shrubs have been prepared for planting during the spring, and 

 several hundred indigenous shrubs and tree sprouts have been 

 gathered into a small nursery. A three-acre nursery has been 

 established in the Northeastern portion of the Park, on ground 

 that has previously been used for agricultural purposes, and is well 

 screened from observation.
