are to be attacked, and the particular advantages for 

 such an attack that are offered by the proposed installa- 

 tion. (See Fronstispiece.) 



A tract of land, about 130 x 350 feet, has been pur- 

 chased, on the edge of the campus. It is proposed to 

 erect in the center of this plot a vivarium building with 

 greenhouse wings and to construct on the land in front 

 of the house a culture pond for fish work. An examina- 

 tion of the sketch plan given here will illustrate the essen- 

 tial features in the construction of the house. It is a rec- 

 tangular structure with a hallway running through the 

 center, from north to south and opening into four labora- 

 tories, one at each corner. East and west from the main 

 house project glass houses of ordinary greenhouse con- 

 struction, which will be utilized for growing animals, but 

 will of course hold plants although these are introduced 

 only for the purpose of furnishing food and shelter for 

 the animals, or to give to the culture animals as nearly 

 as possible the same conditions as they find in the outside 

 world. A similar greenhouse construction projects from 

 the rear of the laboratory structure. Considering the 

 division of space, one may see that each of the four large 

 laboratories has a greenhouse directly connected with 

 it. This plan leaves the north one-third of the block, 

 which lies next the interurban railroad track, to be util- 

 ized as a university storehouse, for unloading freight, 

 receiving supplies, etc. It has nothing to do with our 

 project. 



It is important to notice the general equipment of the 

 laboratories proper. Each one of them is to be supplied 

 with three sorts of water supply, — the city water (which 

 in this case is very hard) , rain water which will be drawn 

 from a cistern constructed on the property near the build- 

 ing, and sea water from an enclosed salt water system, 

 entirely within the building. Each of the greenhouse 

 extensions communicating with a laboratory is similarly 

 supplied, but with less permanent installations for hold- 

 ing the water, so that it may be possible to modify the 

 conditions when demanded by any new experiment. The 

 laboratories and greenhouses have also a supply of cold
