OCTOPUS, BERMUDA AQUARIUM.

The ventilation is excellent, each chamber 

 having air tubes extending above the general 

 level of the embankment. 



The Aquarium is furnished with sea water 

 from a reservoir of stone and cement holding 

 40,000 gallons and situated well above the level 

 of the tanks, to which the water flows freely. 

 The reservoir is supplied from a well dug in the 

 coral rock near the shore, the water being 

 pumped through a three-inch pipe, by a two- 

 horse-power oil engine. A 

 windmill is used as an auxil- 

 iary to the engine. The 

 water from the well is al- 

 ways clear. 



The Aquarium, as has al- 

 ready been stated, is an un- 

 derground structure. Viewed 

 from above it is a rectangu- 

 lar, flat-topped, grass-cov- 

 ered mound, or hill, there 

 being eight feet of earth on 

 top of the masonry. It is 

 situated on Agars Island 

 two miles from Hamilton, 

 and is reached by boat or 

 carriage, the latter involv- 

 ing a transfer of about 100 

 yards bv rowboat. 



There are several ordi- 

 nary buildings of masonry 

 on the island, including two 

 cottages as quarters for of- 

 ficers. The old barrack 

 room is now a well-lighted 

 biological laboratory, with 

 adjacent kitchens, wash- 

 rooms, photographic room 

 and library. Other build- 

 ings serve as warerooms, 

 boat houses and offices. The 

 island has a good dock of 

 masonry, and three fresh 

 water reservoirs. It is much 

 in need of a causeway across 

 the reefs, for the greater 

 convenience of visitors. 



The Aquarium is a pub- 

 lic institution conducted by 

 the Bermuda Natural History Society, in the 

 interest of science. The proceeds from the ad- 

 mission fees of the Aquarium are devoted to 

 the establishment and maintenance of labora- 

 tories for the use of scientists and students from 

 abroad. In 1907-08 there were twenty-nine 

 students of biology from the United States and 

 Canada in the laboratory. Funds are also de- 

 rived from membership dues and popular sub- 

 scriptions. The principal donors to the Society
