TWENTY-FIFTH ANNUAL REPORT 45 



ALTERATIONS AT THE AQUARIUM. 



In order to provide sufficient space for the increase of the 

 collections at the Aquarium resulting from use of the collecting 

 boat, the Society authorized the enlargement of eleven tanks to 

 more than double their former capacity. The cost of this struc- 

 tural alteration to the Aquarium was $2,440. 



The deterioration of the roof of the Aquarium became so 

 marked that in the autumn of 1920 the Society was obliged to 

 take immediate action and make emergency repairs. These re- 

 pairs were completed before the close of the year at a total cost 

 of $900. 



At the same time, defects in one of the boilers at the Aqua- 

 rium developed and called for immediate repair at the cost of 

 $500. 



Both of these emergency items were paid for by the Society 

 and an application has been made to the Board of Estimate and 

 Apportionment for repayment by special revenue bonds. 



Being unable to obtain action from the Board of Estimate 

 and Apportionment for the structural alterations needed at the 

 Aquarium, the Society decided to proceed at its own expense v^ith 

 the removal of the boilers to the front of the building and to use 

 the space vacated for additional tanks. The work involved calls 

 for an expenditure of about $75,000, and plans have been pre- 

 pared by Mr. H. DeB. Parsons, which are nearly completed. The 

 contract for this alteration will be awarded by the Society in the 

 near future so that the work itself can be done during the 

 summer. 



Application will be made to the City for corporate stock in 

 a similar amount for the purpose of providing a new roof and 

 for the construction of an additional story for office space and 

 scientific research. 



MAINTENANCE. 



Park. — The sum of $250,544 was provided by the City for 

 the maintenance of the Zoological Park during the year 1920. 

 While this was a substantial increase over the amount allowed 

 for the preceding year and while it provided in most cases for a 

 proper increase in small salaries, no provision was made for in- 

 creasing the salaries of the staff officers, whose pay had remained
