ordered to desist. Even then the raids continued. The poHce 

 captain of the Forty-first Precinct was appealed to, and promptly 

 doubled the force of policemen patrolling the Park. The raiders 

 cunningly dodged the policemen, and very defiantly went on. 

 Further reports to Captain Fitzpatrick resulted in the detailing of 

 two detectives in citizen's clothes, who promptly arrested a num- 

 ber of persons, and, for a time at least, checked the ardor of the 

 others. 



But even now the Zoological Park is by no means secure from 

 damage at the hands of miscreants. The setting of forest fires 

 and the destruction of valuable trees by tramps and boys engaged 

 in smoking out squirrels, has indeed been permanently stopped ; 

 but not until several of the Society's regular employees are com- 

 missioned as special policemen, and a sufficient number of depre- 

 dators caught red-handed and severely punished, will the Zoo- 

 logical Park be known as a good place for miscreants to avoid. 

 In view of this necessity the Executive Committee has already 

 secured the appointment of the Society's Chief Forester as a 

 special policeman. 



CIVIL ENGINEERING WORK. 



Ever since January i, 1897, Messrs. William Barclay and H. 

 de B. Parsons have been the consulting engineers of this Society 

 and furnished advice and services as occasion required. During 

 the year 1898 the most noteworthy service rendered by them was 

 the planning of a very complete and perfect, as well as economical, 

 system of water supply and sewerage for the whole of the Zoo- 

 logical Park that is to be devoted to collections. They also de- 

 signed a highly satisfactory system of plumbing for the Bear Dens 

 and the steel-pipe skeleton frame to carry the wire netting of the 

 Flying Cage. It is only just to add that because of the fact that 

 their services were required by a scientific society, and not by a 

 money-making concern, these gentlemen have voluntarily ren- 

 dered bills for less than half the sums that would otherwise have 

 been charged as a fair compensation. 



In addition to the valuable services of our consulting engineers, 

 Mr. George M. Beerbower was regularly employed as engineer 

 and draughtsman to stake out on the ground the various Hues of 

 the official plan of the Zoological Park, and perform general work 

 in his line. Survey work was prosecuted vigorously throughout
