livery of public free lectures on aquatic animal life. The 

 building in which the temporary aquarium was installed 

 is unsuited for exhibition purposes, and the tanks avail- 

 able not proper for a good or permanent display of fishes. 

 They had belonged to the State and were used by it at 

 the Expositions of Chicago and St. Louis. 



The temporary aquarium was installed by me in three 

 weeks, and it is still in operation and visited by about 

 6,000 people weekly. The first year of its existence there 

 were over 260,000 visitors. Twenty-seven tanks and 

 about that many species of fresh water fish comprise the 

 exhibit. 



No work has been done towards the completion of the 

 permanent aquarium since October, 1912, when the sea 

 water house was within about six weeks of completion. 

 The funds provided for the completion of the sea water 

 house and possibly the fresh water house are embodied in 

 a municipal loan authorized last winter, but which will 

 not be available until about October, 1913, perhaps not 

 then. 



The tanks in the sea water house will be made of con- 

 crete and the majority of them will be seven feet long 

 each, and one 12yo feet. 



Lead lined pipe or hard rubber pipe is almost univer- 

 sally in use for conveying sea water to and from tanks, 

 but lead lined pipe very frequently does not give perfect 

 satisfaction, and hard rubber pipe is exceedingly expen- 

 sive. After mature deliberation I determined to try the 

 experiment of testing the utility of wood pipe. A four- 

 inch pipe of that material for the supply pipe is now in 

 place, and five-inch wooden pipe for the out-flow will be 

 used, together with terra-cotta. 



I can see no reason why wooden pipe should not be as 

 efficient as hard rubber and much better and safer than 

 lead lined pipe. It certainly will not corrode, nor leak, 

 and it has been in successful use for more than 30 years 

 in the oil regions for conveying salt water from the oil 

 wells and it is used almost exclusively in the coal mining
