84 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1913. 



A bridle path was laid out near the bank of the creek throughout 

 its entire length in the park, and a rustic walk, mainly parallel to the 

 roadway, was built from the concrete bridge to the north entrance. 



Early in the year the first section of a retaining wall was built 

 in the ravine opposite the point at which Ontario Koacl reaches the 

 park, and later a second section was built above this, giving the wall 

 a total height of 18 feet. 



A small retaining wall was built, also, at the mouth of the little 

 rvni at the northern edge of the park near Klingle^ Road to prevent 

 further erosion there and protect valuable forest trees which are 

 being undermined. 



A small amount of riprapping was done at three places on the 

 banks of the creek. 



Just before the close of the year work was begun on the old ele- 

 phant bam to fit it and the adjoining yard, then occupied by tapirs, 

 for the temporary accommodation of the two young African ele- 

 phants wdiich had been secured from the zoological garden at Giza. 

 A new yard, Avith a pool, for the tapirs was built next to the new 

 elephant house, the work on this being well under Avay at the close 

 of the year.

Food house (from 1913 appropriatiou) $3,050 



Inclosure and shelter for ostriches 450 



Inclosure and pool for wood ducks 200

Through the generosity of Mr. John B. Henderson, jr., there was 

 completed in the autumn of 1912 an outdoor cage for parrots which 

 had heretofore been confined in the bird house. The cage is 24 by 

 40 feet, and about 26 feet high, has a steel framework and is covered 

 with strong wire netting of special construction. Several species 

 of cockatoos and macaws, and one species of Amazon parrot, in all 28 

 specimens, were placed in the cage, and, with few exceptions, have 

 been thrifty and appear to enjoy their outdoor freedom. 



MAINTENANCE OF BUILDINGS, INCLOSURES, ETC. 



It was necessary to make quite extensive repairs during the year, 

 so that the expenditures for upkeep were somewhat larger than usual. . 

 New concrete floors were laid in two of the largest bear yards, and 

 the pools rebuilt. The concrete base of the partitions between the
