The well-boat Seahorse was of the greatest service to the 

 Aquarium during- the summer in keeping up the collections and 

 in supplying food. The boat made fifteen trips, gathering 935 

 fishes of forty-one different species in addition to invertebrates 

 which were placed on exhibit or used for food. 



ALTERATIONS AT THE AQUARIUM. 



As stated in the last Annual Report, conditions at the Aqua- 

 rium became intolerable so that plans and specifications were 

 prepared by Mr. H. de B, Parsons for the removal of the boilers 

 from the old, insanitary quarters which were inundated at high 

 tide to a new waterproof basement under the front of the build- 

 ing. The Society owes Mr. Parsons a debt of gratitude for his 

 painstaking and sympathetic work in planning and supervising 

 this work. 



On April 30, 1921, a contract for excavation of the basement 

 and construction of a new pump and boiler room was awarded to 

 Spencer, White & Prentis for $24,500. The total cost, with ex- 

 tras, amounts to $26,650.25. $38,691 have been spent on new- 

 boilers, machinery and refrigerating compressor. The main con- 

 tract for this work, with extras, was given to James McCullagh, 

 Inc. The old high-pressure boilers and steam pumps have been 

 replaced with small, low-pressure boilers and electrical pumps. 

 The work is nearly completed and will involve a total expenditure 

 of $65,341.25, $53,635.02 of which have been paid, leaving a re- 

 mainder of $11,706.23 to be paid. 



The cost of these alterations has been charged against the 

 Sage Endowment Account. It is intended to spend an addi- 

 tional $10,000 in building a memorial entrance to Margaret 

 Olivia Sage. The Society desires, in this way, to express its 

 appreciation for the noble benefaction of Mrs. Sage which made 

 possible these much needed changes. 



Owing to the generosity of one of the Board of Managers, 

 Henry D. Whiton, Esq., $10,000 have been provided for the con- 

 struction of large exhibition tanks to fill the space formerly occu- 

 pied by the machinery. This will increase by one-fifth the ex- 

 hibition space of the Aquarium. 



The foregoing work will involve a total of about $75,000 

 and will constitute a gift from the Society to the City of New 

 York. The Society is glad to be able to state that this gift was
