REPORT OP THE SECRETARY. 71 



As there has always been great difficulty in keeping the monkeys at the park 

 In a proper condition of health, it was decided to transfer all specimens of 

 quadrumana to this building and to add such others as would serve to represent 

 the order. Funds were lacking for purchasing any of the larger or anthropoid 

 apes, but there is a fair collection of specimens of both New World and Old 

 World monkeys, which attracts great attention, and is appreciated by the public. 



The grounds about the building have been graded, improved, and planted, and 

 contracts let for a concrete walk along two sides. 



ADDITIONAL BEAR YARDS. 



Contracts were made for the floors and steel work of two additional yards 

 in the series already begun. These yards will each have a width of 40 feet at 

 the front and a depth of 32 to 40 feet. They will be similar in all respects to 

 those already built, now occupied by polar bears and Alaskan brown bears. 



A concrete walk, with a width of 12 feet, will be constructed at the same time 

 that the pavement is put in for the yards. 



IMPORTANT REPAIR WORK. 



The flying cage was repainted throughout, a new roof was put on the llama 

 house, the aquarium roof was repaired, new supports put in for the tanks, and 

 other necessary repairs made ; the temporary building used for blacksmith and 

 carpenter shop and in which also the boilers of the central heating plant are 

 located was repaired and the walls ceiled on the inside, so that the building 

 might be kept at a reasonably warm temperature during the winter. 



Several of the old outdoor cages, which had become unsafe through decay, 

 were replaced by new ones. A considerable part of the wire fencing around 

 the American bison paddock had to be renewed and a large amount of other 

 fence repairs had to be made. The deer shed, which was so badly weakened by 

 decay that it was no longer safe, was removed. The site of this shed in the hill- 

 side near the creek was so damp that it was found to be unhealthy for the 

 animals. 



ADAMS MILL ROAD. 



Heavy, torrential rains almost completely denuded of surface layer the steep 

 portion of this road, about 1,700 feet in length, and the larger stone became so 

 loosened that the road was hardly safe for use. As this is one of the principal 

 driveways of the District, much used for pleasure driving, it was considered 

 imperative that it should be put in a safe condition at once. It was thoroughly 

 overhauled and resurfaced during the autumn of 1906. 



A new walk was built to connect the log bridge, by way of a picturesque 

 ravine, with the more important animal buildings. A rock work was built 

 with bowlders at the head of the ravine and the waste water from the aquarium 

 tanks and hydraulic pump carried there to form a cascade. 



PLANTING. 



Planting was carried on at suitable times throughout the year, as far as 

 available funds permitted. The whole park should be carefully gone over and 

 the forest be properly thinned so that the trees can have an opportunity to 

 develop. At present much of it is too thickly wooded.
